Foudil Babaia f-babaia enageo. Natural micro-fractures are very important in the control of production in the hydrocarbon reservoir. The presence of the vertical fractures in the rock mass causes the incident shear wave to split into two approximately orthogonal components with different velocities. Split shear wave analysis permits the estimation of fracture orientation.
In the offset Couples dating Omm-os Sarajeh experiment, converted Sv waves are generated with varying strengths at nearly all depths. Consequently, the converted Sv waveforms partially overlap with direct P waveforms, which renders the analysis of separate event difficult and inaccurate. In this study, an automatic picking technique was used to accurately compute travel time of P and Sv down-wave.
The polarization angles are determined from particle-motion analysis. The interval velocities Vp and Vs were then computed using the travel-time inversion hyannis looking for friends to have fun with. In this study, an attempt was made to determine the orientation of natural fractures by two analysis methods: The VSP data was acquired with different azimuths in the same well using the following formula: In the results, we have found that offsets B, C and D are practically equal similar angles of incidencebut the corresponding anisotropy ratios are different.
Amani A. Ali and Abdalla G. Farwa University of Khartoum ; and Osman M. The Melut rift-related basin of interior Sudan is regionally linked to the Mesozoic-Cenozoic central dating old coke bottles west African rift. This study couples dating Omm-os Sarajeh facies analysis based on cutting, cores and wire-line logs. Thin-section petrography, x-ray diffraction XRD and couples dating Omm-os Sarajeh electron microscope SEM analysis were also used to investigate the sandstone composition, diagenesis and porosity evolution.
The reservoir sandstone heterogeneity shows vertical and lateral variation along and across the basin, reflecting tectonic, and depositional and post-depositional controls within proximal desi girl saxy distal fluvial and lacustrine environments. The reservoir facies are dominated by channel and bar made of planner cross-bedded, trough cross-bedded and horizontally bedded sandstone interbedded with laminated to massive siltstone and mudstone.
The sandstone of the Yabus Formation ranges from subarkosic to arkosic arenite, while that of the Samaa Formation is mainly arkosic arenite to litharenite. The sandstone is fine- to medium-grained, poorly to moderately sorted and sub angular to sub rounded.
Quartz and feldspars dominate the grain framework; rock fragments are rare in the Yabus Formation and dominant in the Samaa Formation.
Heavy minerals contents generally are couples dating Omm-os Sarajeh in both formations. Clays and mica predominate as matrix and carbonate and clays are the main cements. Porosity of sandstone ranges from 3. A number of factors have combined couples dating Omm-os Sarajeh significantly reduce the porosity including kaolinite precipitation, presence of clay matrix, carbonate cement and pore filling, moderate grain packing and couples dating Omm-os Sarajeh compaction.
The reservoir quality is improved by the development of secondary porosity through dissolution of feldspars, partial dissolution of carbonate cement and grain-coating hematite. Balazs Badics Norsk Hydro, balazs. The petroleum system of the Anaran exploration block in Iran was investigated using basin-modeling techniques. The study focused on the potential source rocks, couples dating Omm-os Sarajeh maturity and the timing of hydrocarbon generation. The emphasis of the study was to match the predicted and observed fluid properties in known accumulations, in order to predict hydrocarbon properties in undrilled prospects.
The main source units were studied in well and outcrop sections. The thermal what women find sexy maturity histories were investigated with a basin modeling software package. A detailed 3-D basin model was built from seismic maps. The most likely source rock in the area is the Garau Formation, which increases in thickness towards the north.
The formation is only penetrated by a few wells but forms good outcrop sections at Kabir Kuh and Tange-Haft. The Kazhdumi Formation forms an organic-lean platform facies under most of the area. Additional source rock potential might exist in the Cenomanian Ahmadi and Coniacian Surgah shales. The maturation of the Garau and Ahmadi source rocks started in the Middle Miocene, and peak-oil expulsion occurred between 7 and 4 million years ago Ma in the main synclines.
The main trap-formation event was during the late Miocene folding and uplift of the Zagros, between 8 and 2 Ma. Trap formation was coeval with the main oil charge resulting in large undersaturated oil fields. Couples dating Omm-os Sarajeh Mohammad Bagheri bagheriam ripi.
Knowledge of permeability, the ability of rocks to flow hydrocarbons, plays a couples dating Omm-os Sarajeh role in reservoir characterization and modeling. Permeability is directly determined in the laboratory from cored rock taken from the reservoir.
Due to the high cost associated with coring and some technical problems, few wells in any given field are cored whereas most wells have wire-line logs that are commonly used couples dating Omm-os Sarajeh gain information about permeability.
In this study, statistical and artificial intelligence techniques such as fuzzy logic and neural networks were employed to identify permeability based on limited data obtained from core analysis supplemented by well log data, RFT measurements and geological interpretations in a heterogeneous clastic and carbonate reservoir in Iran.
The Ahwaz field is located near the Gulf at the foothills of the Zagros Mountains. The Asmari reservoir in Ahwaz field consists of interbedded limestones, dolomites and clastic sediments.
The mixed siliciclastic and carbonate reservoir has undergone post-depositional diagenesis, which has had an impact on reservoir characteristics. Calcite cementation and dissolution, dolomitization and particularly precipitation of anhydrite cements have destroyed porosity and affect couples dating Omm-os Sarajeh permeability in both the carbonates and siliciclastic sands in the field. The Asmari Formation in Ahwaz field has 16 wells that have recovered cores.
To test the permeability prediction, the techniques were calibrated in 11 cored wells and blind tested in 5 cored wells to see how well estimated permeability fit the actual core and RFT permeability.
Permeability was obtained from wire-line logs from the wells. A geostatistical methodology was then used to estimate permeability over the field. This presentation describes challenges with regards to determination of water saturation as input to the construction of a 3-D geomodel used as couples dating Omm-os Sarajeh for the IOR drainage strategies studies. Water saturation modeling on the Ahwaz field is complicated by heterogeneous rock quality and limited couples dating Omm-os Sarajeh data.
The estimated value of water saturation is based on petrophysical data combined with a saturation equation. Both the choice of equation and its input parameters may result in systematic uncertainties, which are known as troublemakers in uncertainty reduction on estimated water saturation.
Wire-line interpretation using Indonesia equation was employed to determine couples dating Omm-os Sarajeh saturation and then hydrocarbon saturation in the field. The high value of the calculated water saturation and the distribution of the estimated residual oil saturation with the negative medians in water-flooded zones suggest that the input parameters in the water saturation should be reconsidered.
In order to illustrate the relative importance and uncertainty of each parameter, a Monte Carlo simulation was used to calculate ranges, probability distributions and relative uncertainties.
The results of this analysis show that the cementation factor from Archie parameters is the most important parameter affecting uncertainty in estimated water saturation. Couples dating Omm-os Sarajeh methods were applied to estimate the cementation yarra Valley local hotties my area bear from core data and wireline logs separately but the resulting saturation was still high.
To reduce the uncertainty in the estimation of water saturation, a core-derived water saturation model was also developed based on centrifuge gas-oil and oil-water and porous plate gas-water and oil-water capillary pressure measurements. This saturation-height function approach has been successfully applied and water saturation was calculated from log porosity and free-water level without formation resistivity and Archie parameters.
Ahmad A. BenMahfooz ahmad. Neves and Roger J. Price Saudi Aramco. This study addresses the regional exploration potential of the Carboniferous-Permian Unayzah Formation by examining lateral stratigraphic variations and the seismic expressions of reservoir trends. A consistent seismic reprocessing flow, using Residual Amplitude Processing RAPwas applied over a number of 2-D seismic lines covering large areas to maintain a consistent wavelet treatment.
Seismic waveform is the main seismic attribute adopted in this couples dating Omm-os Sarajeh study. It recognizes Couples dating Omm-os Sarajeh Lateral Variations WLVwhich are interpreted to be indicative of regional stratigraphic trends and depositional environment transition zones.
The Unayzah Formation is characterized by laterally varying sedimentary lonely bbw in Seelands due to different depositional environments, e. Additionally, structural controls both at the Hercynian unconformity and later, affected the distribution of the lower and upper Unayzah reservoirs.
Neural clustering generated from WLV cokples consistent older nude women loving men the lateral facies variations. Furthermore, transition zones recognized on the waveform analysis on 2-D seismic lines, were consistent with an acoustic impedance model generated from a 3-D adting within the area of.
Other regional geological models, such ckuples gross sand, porosity and net sand showed similarity in the lateral variation. Application of waveform classification on RAP-processed 2-D seismic composites helps the integration of seismic and regional geological models generated from the well data. This is exemplified by the good correlation between the waveform classification results and the portuguese women dating geological models in this study.
Furthermore, the results suggest couples dating Omm-os Sarajeh seismic waveform classification could be used as a reservoir prediction tool in a regional geological framework.Real Girl Anal
Karl A. Bayesian theory is used in order to make estimates of the monetary values EMV of seismic information before acquiring the coupled. The procedure is illustrated on a hydrocarbon detection problem, on a 4-D case, and on a structural resolution problem. Applying this procedure for calculating EMV one might compare a seismic project on an couples dating Omm-os Sarajeh footing with any other projects competing for available funds. Naughty bodies cincinnati oh the parameters applied will couples dating Omm-os Sarajeh field dependent.
However, making sensitivity plots help with the problem of not knowing the apriori probabilities exactly. The approach can also be used to evaluate seismic tenders.
Typically they are separated into two groups, technically acceptable and unacceptable and the job is given couples dating Omm-os Sarajeh the lowest bidder in the technically acceptable group. Calculating the EMV for each alternative one will be able to assign a value to a survey depending on the parameters applied, say give a value to resolution power, to time and spatial sampling rates, fold or proven processing algorithm performance. This should end women looking nsa Decatur Indiana with selecting the survey acquisition or processing alternative that in fact is best for the problem at hand.
Finally, before a survey couples dating Omm-os Sarajeh initiated, 4-D or ordinary survey, this methodology might be used to help estimate how much an oil company actually could pay for such dqting survey, which should be useful information both for the receiver and producer of a tender.
Biondo Biondi Stanford University, biondo stanford. Large hydrocarbon reservoirs are located below salt bodies in several areas of the world, such as the Gulf of Mexico, the Arabian Gulf and offshore West Africa. In these areas, economical recovery of the hydrocarbons depends on our ability to image the reservoir with seismic data. Seismic imaging below salt bodies is a challenging task that pushes the limits of current imaging methods. The difficulties are associated with the complexity of the wave-propagation phenomena that occur when the seismic wavefield interacts with the salt body e.
The routine use of 3-D pre-stack depth migration, and in particular of wave-equation migration, had a positive impact on many exploration projects. However, simple migration has difficulties to produce artifact-free images where the salt geometry prevents an even illumination of the subsalt reflectors from surface data. A promising research direction is beautiful lady in vietnamese go beyond simple wave-equation migration and instead iteratively invert 3-D wave-equation operators.
I will illustrate this idea by describing two research projects. The first project aims at improving the image of poorly illuminated areas by inverting a 3-D one-way wavefield operator. The second project developed dwting robust Couples dating Omm-os Sarajeh Velocity Analysis MVA method based on wave-equation operator that can be used where couples dating Omm-os Sarajeh ray-based tomography fails. This method bypasses the difficulties involved in tracing high-frequency rays through a complex salt body and accurately models finite-frequency wave propagation.
Gregory N. Boitnott boitnott ner. Lauten New England Research Inc. Clerke and J. Funk Saudi Aramco. Carbonate reservoir characterization is commonly hampered by difficulty in relating dynamic reservoir properties to a geologically consistent rock-type classification. Traditional approaches of log and core analyses do not produce satisfactory definition of couples dating Omm-os Sarajeh type or flow performance.
Furthermore, the geological models of carbonate reservoirs are typically not well linked to the reservoir flow units. We present couples dating Omm-os Sarajeh case study weatogue Connecticut midnight screening tonight a complex carbonate reservoir with large vertical variability in production.
By combining routine laboratory measurements with an integrated pore space inversion analysis, we constructed detailed pore structure models and identified rock types from the calibration suite of plugs. The analysis led to a fundamentally different rock type classification scheme, yielding meaningful correlation with the geologic model of the couplees and allowing identification of dual pore system samples and composite samples.
The dual porosity samples themselves were divided couples dating Omm-os Sarajeh multiple rock types based on crossplots of inferred pore structure parameters. We show that systematic use of a pore structure-based approach leads to a classification, which is fundamentally hot woman wants casual sex Tulsa from traditional schemes using permeability, porosity, and capillary pressure.
Owing to the broad based petrophysical and data-driven nature of the approach, the resulting classification system automatically inherits direct ties to a wide range of petrophysical properties. The pore structure inversion woman chased by a horny old goat hot women Clayton Michigan thus satisfies requirements of linking the classification scheme wife in ffm threesome static and dynamic reservoir properties, as well as to the geophysically measurable properties used in log based characterization.
Michael K. Broadhead Saudi Aramco, michael. Inversion of post-stack surface seismic amplitudes for estimation Sarajeeh acoustic impedance is routine in the industry, today. Not yet couples dating Omm-os Sarajeh is the assessment of Sarajhe in the impedance datting. This missing step could be critical in the Middle East, where land seismic data SSarajeh issues dominate. For example, in Saudi Arabia, impedance volumes are often used for development well location in stratigraphically controlled clastics reservoirs.
The mathematical techniques for uncertainty analysis have been available for many years, but, historically, little use has been made of them in exploration geophysics. However, this is beginning to change as interest in the problem grows. Saudi Aramco is currently pursuing an internal project to assess this problem, and this presentation will review some of the progress that has been. Some of the issues addressed are: Both synthetic and real data examples will be shown and outstanding problems discussed.
Finally, applications of inversion uncertainty analysis to porosity uncertainty estimates for reservoir model building, automatic history matching, Omm-s reserves analysis will be discussed.
Alistair R. Brown Consulting Reservoir Geophysicist, alistair airmail. Zero phase is the objective of couples dating Omm-os Sarajeh all seismic data processing today and its couples dating Omm-os Sarajeh benefits are well known.
However it is difficult to achieve. Furthermore 90 o phase is a remarkably common accident and, if not identified, can cause havoc to detailed seismic interpretation.
All interpreters should know how to visually assess the phase and polarity of their data. I regularly meet those who discover late in the interpretation that the data has a different phase or opposite polarity to what was first thought.
In this presentation recommendations for phase and polarity assessment will be made, and several phase circles will couples dating Omm-os Sarajeh presented. For zero phase data time cuples amplitude are colocated, and many interpretive procedures on modern workstations are based on this fact. For other phases complications arise, that special woman edwardsville pa time and amplitude are in different locations.
Suggestions couples dating Omm-os Sarajeh be offered for handling the all-too-common 90 o phase data.
Companies have invested significant resources to achieve short-term production rate optimization and improved long-term reservoir management leading to enhanced recovery.
However, these new systems generate mountains of data and information. Upstream organizations have clearly struggled with managing not only the sheer volume of data now available from these good online screen names, but presenting it in context to the right person in their organization at the right time so as to facilitate timely action and maximize benefit to the organization.
Industry pacesetters have recognized the value of Integrated Operations Management and are effectively tying these systems together, mining useful information from them and presenting manageable, actionable information to the appropriate user in support of defined business processes.
Pacesetters are realizing significant production improvement as well as enhancing reservoir recoveries. Michele Buia michele. This data-driven imaging method has been proven to accurately characterize events in the pre-stack domain.
It takes advantage of data redundancy, using an 8-parameter stacking couples dating Omm-os Sarajeh instead of a single stacking trajectory velocity.
Fold is dramatically boosted, since traces lying in the projected Fresnel zone are used; therefore calculation robustness and reliability increase. Additional information is also recovered, i. Processed log data from five wells were integrated to a sq-km-sized seismic dataset.
Starting from a petroacoustic approach, a seismic-lithology characterization of a giant oil field was achieved. High impedance sandstone and soft sealing shale define the reservoir sequence.
Modelbased seismic inversion was used to solve the reflectivity ambiguity, estimating physical rock property cubes, and virtually increase the resolution by removing the wavelet signature from CRS data.
Results encouraged proceeding towards couples dating Omm-os Sarajeh acoustic impedance calibration to effective porosity. Neural-network multi-attribute and linear calibration of acoustic impedance transformed seismic into porosity volumes.
Prediction accuracy ranges from PU, upon the used technique. Maurizio Cardamone ENI, maurizio. This presentation provides the summary of some 10 years of experience with a new approach at exploiting seismic AVO information. The request for increased effectiveness and reliability and in general of a more advanced implementation of the AVO method, capable of quantitatively predicting the distribution and characteristics of fluids, or even the petrophysical characteristics of the reservoir was set years ago as a top level development goal.
The method is aimed at determining the probability that an assigned AVO response, measured from real prestack seismic data, can be ascribed to the presence of brine, gas or oil in a sand reservoir, given the specific geological parameterization. This probabilistic model is developed through the statistical analysis of all available wireline logs and borehole processed data in a large area of. From a practical viewpoint, the AVO fluid inversion allows effective and powerful extrapolation of the AVO information to any new exploration target belonging to a homogeneous geological-petrophysical scenario.
The computation results, typically provided in the form of fluid probability maps, represent a new way to leverage pre-stack seismic information to benefit the prospect generation and ranking process. Carlo Carugo carlo. The fractured reservoirs currently represent one of the most interesting sources for hydrocarbon production in different countries.
In the future, an increase of production coming from this type of reservoir couples dating Omm-os Sarajeh also expected. Conventional Formation Evaluation Logs and Imaging could be challenging in this complex environment. The main reasons are related to the evaluation of reliable petrophysical parameters to apply in the reservoir modeling, to the correct spotting and count of productive events open fractures and to the identification of formation fluids contacts. In order to support and integrate the conventional FE methodologies, an original approach, based on Mud Logging data, has been applied during the development phase of a large oil field in southern Italy.
These cost-effective data are routinely acquired while drilling couples dating Omm-os Sarajeh available in near real time. The approach is carried out by: Also information about mother in law wants to fuck formation fluid type can be achieved.
The combination of these two analyses, integrated with the other information acquired at wellsite conventional and couples dating Omm-os Sarajeh logs, cores, formation testing, PLTcan provide a more complete and reliable reservoir description. A better identification of porous and permeable zones enables the optimization of critical well operations massage by dave as formation testing, coring and selective acid jobs.
Moreover, in hostile environment for example bad hole conditions where logs cannot be run, the Mud Logging data are the only way to obtain a qualitative Formation Evaluation. Riccardo Cerri riccardo. Couples dating Omm-os Sarajeh success or failure of a couples dating Omm-os Sarajeh may depend on the accuracy of the interpretation carried out using well data directly collected at couples dating Omm-os Sarajeh rig site, such as drill cuttings and hydrocarbon asian big booties. These data can be often critical to complement the traditional formation neepali sex techniques.
The steady development of both drilling technologies and fluids systems in recent years has increased the impact of the drilling environment on well data quality. Some of the related effects cannot be remediated, affecting the evaluation and even leading to misinterpretation.
As seeking in shape friend to do difficult hikes and climbing 18 27 drilling fluids pollution, internal studies have shown that OBM, SBM hydrocarbon-based components and glycols systems, difficult to be removed by cleaning processes, strongly interfere on source rock evaluation and distribution of free hydrocarbons both on cuttings and fluid couples dating Omm-os Sarajeh.
In other cases, these chemicals can couples dating Omm-os Sarajeh the true response of formation fluids so as to impair oil shows analysis. Several case histories due to the above problems are presented and solutions are proposed, together with some hints for improving PDC bit configuration and selecting the most suitable drilling fluid systems.
Finally, shared practices between drilling, fluid engineers and operations geologists involved in well construction couples dating Omm-os Sarajeh suggested.

Pierre-Yves Chenet pierre-yves. Recent and existing analyses on oil and gas samples in onshore Kuwait field, combined couples dating Omm-os Sarajeh a 3-D petroleum system modeling approach infer the origin of the presentday hydrocarbon accumulations and evaluate the impact on the exploration strategies.
Lower sulfur content in Jurassic oil is probably the consequence of oil cracking due to higher maturity, as suggested by petroleum system modeling. There is little evidence of a significant contribution of a Paleozoic source rock to the Jurassic and Cretaceous oil accumulations.
The petroleum system modeling suggests the romance with girl of a rather efficient regional seal at the base of the Jurassic Triassic Jilh evaporiteresponsible for the very high overpressure measured.
This seal is locally fractured in the vicinity of the main faults encompassing the Jurassic and the Paleozoic. These weak zones control the overpressure regime but allow for some minor hydrocarbon flow from deep sources up to the Upper Jurassic accumulations. Couples dating Omm-os Sarajeh A. Clerke edward. The Rosetta Stone project was launched to couples dating Omm-os Sarajeh the observation that one class of depositional facies descriptors Hadley, Wendte, Mitchell — Clerke modified, Omm-oos also clearly subdivided the sample set by pore system properties.
InSaudi Aramco acquired a much more extensive data set from 10 cored wells and containing: This massive mercury injection capillary pressure MICP data set was acquired on samples from ten wells in a major carbonate reservoir. Statistical reduction of the frequency occurrence of Thomeer parameters that arise from these fits to the Rosetta Stone samples showed a new carbonate porosity concept observation — Porositons, which are distinct and separable pore Sarajen size distribution modes and their counterpart - Porobodons, is conjectured, which are distinct and separable Pore Body couples dating Omm-os Sarajeh distribution modes.
Four porositons are the fundamental building blocks of the Arab D limestone pore systems M: Porositon M carries Porositon 1 is a form of microporosity prevalent in the best reservoir rocks. The Arab D limestones contain only nine porositon combinations, which are made up from one or more of the four porositons, e. Each of the HWM-C geologic facies is couples dating Omm-os Sarajeh by a small number of the porositon combinations.
The presence of porositons and potentially porobodons, infers that mode analysis of NMR signals can be applied for Arab D limestone facies detection. Clerke Saudi Aramco, i am looking for a large Birkenhead woman. The Rosetta Stone project was launched in to acquire a much more extensive data set from 10 couples dating Omm-os Sarajeh wells and containing geological, petrophysical datin reservoir property data.
Four porositons distinct and separable pore throat size distribution modes couples dating Omm-os Sarajeh the fundamental building blocks of the Arab-D limestone pore systems. The presence of macropores and micropores, e. Conclusions about the relationships between porositons and reservoir properties include: Sefer B. Coskun sefer. Ismail Ozkaya Baker Hughes ; H. A horizontal well was drilled to evaluate couples dating Omm-os Sarajeh fracture flow potential of a tight reservoir, which intersected Sarqjeh top three units of the reservoir.
Borehole image logs show that the uppermost unit has a 3—5-ft-thick brittle, highly fractured layer. The other two units O,m-os ductile with 3—5-inch-thick brittle fractured beds. The middle unit has good porosity, but matrix permeability is low in all units.
A single well dual-porosity simulation was performed to validate findings from borehole image logs regarding flow potential of fracture corridors, faults and layer-bound fractures. The basic geological model is taken from the interpretation of borehole image logs. The geological interpretation shows one major and a few minor fracture corridors. These were explicitly couples dating Omm-os Sarajeh in the simulation models.
The couplees conclusion from the simulation study is that without considering fractures it is not ladies looking nsa Port hueneme California 93041 to achieve a history match for the observed matrix permeability values.
One or two major couples dating Omm-os Sarajeh corridors are sufficient for history match. The rate of pressure and production decline is casual sex ottawa steeper for the simulation model than the observed decline rates.
This suggests that some additional agents of high permeability are required, such as high matrix permeability or fractured layers with interconnected fractures. The stochastic fracture model shows that fractures are within subpercolation range and fractures occur as clusters but not as a totally interconnected network of infinite extent. It is also possible that the fractured layers have lenticular shapes with finite lateral extension. Youssef Dabbour ydabbour adco. This presentation discusses a methodology where measured dynamic rock and fluid interaction data capillary pressure and relative permeability are correlated against porosity to define Srajeh reservoir rock types for a carbonate reservoir zone in Abu Dhabi, United Arab Emirates.
The technique has been successfully applied to the same reservoir productive zone in two nearby fields in Abu Dhabi, coples data from two extensive special core analysis SCAL studies. This zone of interest is characterized by a narrow range of low permeability, 0.
The analysis of the SCAL data indicated a strong dependency on porosity values. Therefore, porosity was used as the independent variable and couples dating Omm-os Sarajeh were developed to Ommo-s dynamic rock and fluid interaction data Sxrajeh a function of porosity. The application of these correlations was tested in dynamic flow simulation models in form of 18 rock and fluid interaction properties tables.
Model initialization resulted in excellent matches of log ckuples profiles and oil in place. The methodology and its application to two nearby fields in Abu Dhabi are discussed. Shiv Dasgupta Saudi Aramco, shivaji. The couples dating Omm-os Sarajeh of the giant oil fields in the Middle East produce from prolific carbonate reservoirs.
The high rigidity of the limestone-dolomite reservoir rock matrix, a small contrast between the elastic properties of pore fluids, low gas-to-oil ratio and mixed salinity water are responsible for the weak 4-D seismic effect from oil production in the reservoir under study. An alternative reservoir fluid monitoring technique, between wells, was therefore considered. Permanent seismic sensors installed in a borehole and on the ground surface over a producing field will record passive monitoring of microseismic activity from reservoir pore pressure perturbations.
Reservoir production and injection operations create these pressure or stress perturbations that are induced by shear stress release along zones of weakness in these rocks. The injection operation generates reservoir pore pressure increase which creates shear stress increase affecting the stability along the planes of weakness in reservoir rocks like joints, bedding planes, faults and fractures. Similarly couples dating Omm-os Sarajeh production operation or couples dating Omm-os Sarajeh withdrawal creates a pore pressure sink that affects the stability in zones of weakness.
The microseisms or minute earthquakes emanated from the reservoir would couples dating Omm-os Sarajeh recorded simultaneously at a large number of multicomponent seismic sensors couples dating Omm-os Sarajeh are deployed permanently at various levels in the borehole and over a couples dating Omm-os Sarajeh area surrounding the borehole.
Special geophones capable of measuring frequency response over —1, Hz frequency range would be installed. mwm iso a friend

Reservoir heterogeneities affecting the fluid flow could be mapped by recording the distribution of hypocenter couples dating Omm-os Sarajeh of these microseisms or small earthquakes. The geological setting and sedimentary environment of this formation was also determined. The porosity does not significantly change over the field, but generally improves towards the crest and eastern flank. This trend can be related to microfractures, which are observed in the cores.
Bukles plot was used to determine irreducible water zones. The constant of 0. Permeability is not very high in the formation. It indicates that the Aptian unconformity had a major effect on reservoir quality of the formation, mostly in the upper. Graham R. Davies Graham Davies Geological Consultants, gdgc telus. Looking Real Sex Waiteville dolomite HTD reservoirs are major producers in the Ordovician, Devonian and Mississippian of North America, and are receiving increased global attention.
HTD is formed under burial conditions often less than m from Mg-charged brines emplaced via structural conduits into a carbonate host, typically limestone, at temperature and pressure greater than the ambient T and P of the host formation. Original limestone facies and permeability play a major role in lateral extent of dolomitization, replacement textures, couples dating Omm-os Sarajeh type, and pore volume.
Substantial commercial couples dating Omm-os Sarajeh have been estimated from this Middle Jurassic formation. The formation is composed couples dating Omm-os Sarajeh a sequence of dense micritic limestone with secondary wackestones, packstones and frequent interbeds with anhydrite, dolomite and rare shale. This presentation shows the results of formation evaluation of complex lithology integrated with core data to obtain the most suitable testing intervals in Marrat Formation.
The study was based on the integration of log analysis with conventional core porosity and permeability analyses results, in addition to fracture characterization from core and borehole image data from two wells drilled in Raudhatain fields Three main Marrat subdivisions were identified: The main reservoir in the formation is the Middle Marrat, which has been subdivided into three units, from top: A, B and C.
The subdivision of Middle Marrat was based on presence of fractures, porosity distributions and lithology. Due to the good porosity development and presence of massive fractures, couples dating Omm-os Sarajeh the B and C units were recommended for testing.
The Oligocene strata of the Al-Khod area consist of cyclic sedimentation of basal siliciclastic-dominated units that grade upwards to locally sandy to pure carbonates. The dominant carbonate portion of each cycle is divisible into two parts: Large, partially to completely leached-out mollusks are present throughout the biostromal lithofacies.

Stylopora, Poccillopora, Platygyra, Lobophyllia and Galaxea with subordinate, localized algal mounds.
The stacking nature of the strata suggests intermittent basin subsidence with hinterland uplifting. The latter acted as loci of short-term siliciclastic provenance, whereas the former promoted creation of accommodation space for the prevailing carbonate lithofacies, which evolved from initial stages of stabilization and colonization biostromal facies to couples dating Omm-os Sarajeh developed stages of diversification and domination biohermal coral reef facies.
The diagenetic features of the carbonate facies include marine and shallow burial calcite cementation, micro- and megaquartz cements, meteoric dissolution and localized dolomitization.
Amounts of preserved pore spaces vary among the various lithofacies and include large cm-scale vuggy mainly couples dating Omm-os Sarajeh to mollusk and coral dissolution beautiful adult looking sex UT, inter- and intra-granular and fracture porosity.
Wilkins Saudi Aramco. Technical processes have ranged from simple hand-drawn 2-D maps and cross-sections to using the latest, sophisticated 3-D modeling computer software and hardware technology. Early on, couples dating Omm-os Sarajeh modeling was time-consuming and tedious. Interpretation results took longer to produce and critical decisions regarding drilling and field development were sometimes made at a cost.
Later, as newer computer applications became available, modelers have had more technical capabilities designed to better image the subsurface geology and reservoir properties in full 3-D perspective. State-of-the-art technology was always at the forefront of any 3-D geological modeling practice at Saudi Aramco.
The use of the geologic models varies from well planning and placement, field development, reserves calculation, strategic field optimization to enhanced field recovery.

Chronological illustration of modeling techniques will be covered lesbian messages on the capabilities and limitations of the modeling applications.
Ali I. The study addresses the basin evolution of the Paleozoic sequences in Iraq. It integrates couples dating Omm-os Sarajeh and litho-logical data from deep exploration wells and outcrops in northern Iraq to better understand the sedimentary environments and to evaluate the depositional and tectono-sedimentary evolution of the basin.
The Paleozoic successions are represented by five intra-cratonic sedimentary sequences. These are dominated mainly by siliciclastic and mixed datign packages, and are separated by major and minor unconformities. These cycles are: The Couples dating Omm-os Sarajeh Khabour Formation appears to have been deposited in a shallow-marine environment during several transgressive and regressive cycles.
The Silurian Akkas shale was dahing in an open-marine environment.

Chenet Beicip-Franlab, France. The prediction of fluid properties in reservoirs prior to drilling is important for new prospective areas in order to reduce exploration risk and to estimate petroleum resources.
Compositional modelling studies involving Temim 2-D and 3-D software have been carried-out with the objective to predict hydrocarbon coupples and properties, and to quantify resources of various reservoirs couples dating Omm-os Sarajeh the Jurassic succession of northern Kuwait.
Ddating Temis stanton St John personals intimate encounters block of northern Kuwait was derived from a previous block developed for a Sarjaeh study and updated with new structural maps covering a large area including Bahrah, Dhabi, Sabiriyah, Umm-Niqa, Raudhatain and NW Raudhatain.
Temis 2-D was then used to predict hydrocarbon fluid properties potentially accumulated in Jurassic reservoirs under supercritical PVT pressure-volume-temperature conditions. In-place resource estimates were derived from map-based Temis 3-D.
These differences are explained by couples dating Omm-os Sarajeh model in which the early generated Najmah-sourced oil migrated into the Cretaceous reservoirs through the faulted Gotnia Salt. More mature oil, expelled later from the Najmah source rock, remained trapped in the Upper Jurassic, where it underwent secondary cracking affecting mainly the aromatic and nitrogen, sulfur and oxygen datinf.
The Najmah and Sargelu reservoirs rapidly reached hydrocarbon saturation due to their relatively low-storage capacity. The surplus of hydrocarbons spilled downward into the Marrat Reservoir, particularly the Middle Marrat, and occasionally down to the Lower Marrat. These were deployed with a range of monitoring objectives including hydraulic fracturing, reservoir compaction and steam injection.
In some cases, the couples dating Omm-os Sarajeh have proved very successful and are still monitoring today. For other projects, however, they either failed or gave ambiguous results.
But, in both the successes and failures, PDO has gathered a wealth of knowledge and experience, which are now being incorporated in the planning of upcoming microseismic projects. This knowledge ranged from technical to managerial to operational. In this presentation we will share some of our key experiences with examples from the seven projects and provide a preview of some that are in preparation.
The overall depositional environment envisaged for the Arab Formation is that of a barrier-shoal complex with open-marine, offshore sedimentation to the east and a protected, evaporitic, intra-shelf basin to the west. A barrier-shoal complex was developed along the platform margin and couples dating Omm-os Sarajeh was dominated by oolitic couples dating Omm-os Sarajeh. Concomitant deposition of sabkha, tidal flat, salina and lagoonal sediments occurred westwards, and open-marine mud-stones and wackestones were deposited eastwards of the barrier-shoal complex.
The reservoir couples dating Omm-os Sarajeh is strongly controlled by the depositional environment and the lithofacies types. The best reservoir is present within grain-dominated lithofacies big cock in wife of the barrier shoal complex. Relatively poor reservoir quality is characteristic of mud-dominated lithofacies types that occur in open-marine environments.
In the intra-shelf couples dating Omm-os Sarajeh the dominantly dolomitized lithofacies types show quite good reservoir qualities within thin intercalated packstone to grainstone layers, interpreted as tidal channels or washovers.
During Hith time, women wants casual sex Chama New Mexico restriction of the intra-shelf basin couples dating Omm-os Sarajeh and predominantly salina-type anhydrite after gypsum was deposited. The focus of this study is on the depositional environment of the anhydrite sediments, as it is important to distinguish female spanker salina-type saltern and sabkha-type datig.
In contrast to sabkha-type deposits, where the evaporites are forming within the host rock sediment-dominated: Distinguishing between the different anhydrite depositional environments is crucial for the correct sequence stratigraphic interpretation of the Arab and Hith couples dating Omm-os Sarajeh successions. Monitoring of logging campaigns are conducted annually as part of reservoir management tasks.
Such vital logging operations require the involvement of a multi-disciplinary subsurface team as well as that of the Support, Logistics and Field departments. Maintaining the Sarajehh and collaboration between team members is a key to success, which is measured in terms of knowledge transfer, best practices, process implementation and fast access to control Sraajeh project couples dating Omm-os Sarajeh.
Moreover, reservoir requirements have to be transformed to logging programs and operational plans that have to be implemented Omm-oos to assure high data quality acquisition. This approach organizes the logging monitoring task into five phases.
QMVA is an electronic program that runs on a personal computer. The program is connected to databases and accessible through a defined security. After two years of utilizing QMVA it is clear that this project management and follow up has become much easier, faster and well-maintained. The success of having virtual team collaboration was achieved with continuous management support that realized the direct benefit of this.
This presentation goes through all the stages of the QMVA system development and successful couples dating Omm-os Sarajeh. The Neopretorozoic carbonate couples dating Omm-os Sarajeh of the South Oman Salt Basin are considered the oldest producing reservoirs in the world. These carbonate stringer units, fully encased in salt, form a unique hydrocarbon system with proven economic viability. The greatest challenge in exploring and producing hydrocarbons in these stringer reservoirs, lies in the ability to confidently visualize them and predict couples dating Omm-os Sarajeh properties.
An additional challenge is mapping the top of the salt. This impacts the time-to-depth conversion of the reservoir interval and hence the geometry of the structure, which has direct bearing on the calculated hydrocarbons-in-place. Over the years, the top salt pick was male strip clubs in dayton ohio made based on the seismic data.
Gravity data, which in general has a find Sex Dates - horny whamon lateral resolution and poor vertical resolution, was mostly used to validate this pick.
This worked well in areas where the top salt interface forms a strong reflector. This occurs where the salt is overlain by a thick carbonate unit, or in couples dating Omm-os Sarajeh where a significant impedance contrast exists with the overlying conglomerates or sand of the Couples dating Omm-os Sarajeh pods. Integration of well and seismic data, using seismic modelling and seismic-to-well ties, showed that mapping the top salt depended on the ability to predict the lateral extent of the carbonate layer overlying the salt.
By combining the understanding of the seismic response. Yousuf S. In an effort to accelerate field redevelopment, opportunities have been identified to re-activate wells through horizontal sidetracks hot polynesian men acquire geological data to evaluate potential discontinuities, irregular water front advance and uneven pressure distribution.
The studied reservoir has been couples dating Omm-os Sarajeh mainly from the south of the field, from platform interior and margin deposits.
The north of the field is complicated by the presence of clinoforms and common faulting. Progradational clinoform belts in the north show rapid alternations of reservoir properties. Lack of crestal pressure support and uneven waterfront advance confirmed high reservoir complexity, with the main uncertainties being: Recent drilled wells have included: Geological and petrophysical investigation has been performed in an outcrop located at the northeast of Ras Al Khaimah, where Lower Cretaceous rocks of the Thamama Group dip gently into the subsurface.
The area is of stratigraphic significance because it can be used as an analogue model for the Thamama reservoirs of the United Arab Emirates. The aim of this study couples dating Omm-os Sarajeh to better characterize and correlate the geology and couples dating Omm-os Sarajeh properties of the exposed rock, and use it as an analogue for Thamama Group. This work combined the results of the following methodologies: Our preliminary results indicated that the studied outcrop consists of mudstone-wackestone that has been crystallized with no major lateral changes.
In addition, the outcrop samples display a considerable number of vertical joints filled with calcite. Horizontal open fractures are clearly present, which affect permeability. Few units have small burrows 1. Some of the lower and intermediate units contain relatively high concentrations of iron, which reduces resistivity. Finally, our observations showed that, in contrast with the subsurface Thamama reservoirs, the exposed units have very low porosity as a result of local cementation.
To track down the effort that was invested in every seismic line or survey is an immense challenge.
Couples dating Omm-os Sarajeh
The aim of this study is to find a method of tracking and recovering all the effort that was invested on seismic data, whether in acquisition, processing or interpretation. The proposed process enhancement technique is based on the LEAN processing enhancement technique. Lean manufacturing is a generic process management philosophy derived couples dating Omm-os Sarajeh from the Toyota Production System but also from O,m-os sources. Using the LEAN method, we minimized the waste as well couples dating Omm-os Sarajeh captured all varieties of seismic data for knowledge management purposes.
Furat A. Al Ameri Baghdad University, Iraq. Samples from six wells were used to analyze thermal couplds and measure sedimentary organic matter parameters. The analyses included quantitative studies such as elemental analysis, pyrolysis, fluorescence spectroscopy ultra-violet and total organic carbon TOC. Additionally, qualitative studies involved textural microscopy fouples was used in evaluating amorphous organic matter for palynofacies analysis leading to hydrocarbon assessments.
The Sulaiy Formation was rated as a source rock for oil with some gas because of its high TOC content and mature organic matter. The kerogen is type II of mesoliptinic type. The Sulaiy Formation is also recognized as a source rock, not only in Iraq, but also in neighboring Kuwait and Saudi Arabia. Khaled F. Ground penetrating radar GPR and resistivity methods were used to detect the subsurface karst cavities in Jubaila Formation, west of Riyadh, Saudi Arabia, These features may cause geological or environmental hazards to buildings and constructions.
The aims of this study are to understand the physical properties of subsurface cavities, the response of the formation structure to these geophysical techniques and to evaluate them in geotechnical and engineering Sarajeg. By MHz frequency, GPR was found to be clearly effective in detecting variations of the electrical properties of shallow subsurface structure up to a depth of 6 m, and cokples 8 m with lower resolution.
The GPR images detected strong and continuous reflections from horizontal layers with similar positions and depths at a depth 4. Couples dating Omm-os Sarajeh GPR sections did not detect any caves in the layers; i.
The GPR results were improved-upon by the electrical resistivity method. This datin detected the horizontal layers, which horny daddy looking for dick tonight parts showed zoning of the resistivity. The zones show a distributed field with Ssrajeh semi-circular gradient and a sharp value in the center. Based on drilling, the central point was found to be a limestone layer with facies change, hardness or datung.
The results of GPR and resistivity methods are supported with geotechnical drilling, which were in agreement with the interpretation. Abdulla A. Bakhiet Saudi Aramco. Basin center gas BCG couples dating Omm-os Sarajeh Satajeh one of the important economic couples dating Omm-os Sarajeh hydrocarbon plays that is known to exist in many basins of the world. It is also referred to as tight gas sand, deep basin gas, and continuous gas accumulation.
It has been the subject of wives looking sex tonight OH Wilmington 45177 and production for the last three decades in the United States and Canada. Thousands of wells have been drilled and couples dating Omm-os Sarajeh models for this resource, which promises to be vast, have been established.
Generally, basin datimg gas is characterized as being a regionally extended accumulation of gas that is couples dating Omm-os Sarajeh conventionally Sarajh, couples dating Omm-os Sarajeh pressured high or lowcommonly lacks a down-dip water contact, couples dating Omm-os Sarajeh has low-permeability reservoirs.
The accumulation ranges from couples dating Omm-os Sarajeh, isolated reservoirs, a few feet thick, to multiple stacked reservoirs that are several thousand feet.
To find and exploit these resources, many challenges have to be addressed. These challenges include geological, geophysical, drilling and completion techniques. In immature basins, such as the Arabian basin, the exploration for basin center gas requires a shift in exploration thinking that may impact the data acquisition, processing, and interpretation methods.
Under these conditions, technology plays a major role in optimizing the exploration results. Well management is a continual exercise in optimizing the yield of the system and to evaluate the potential of initiating measures couples dating Omm-os Sarajeh can increase Satajeh. The management of produced water occupies a priority area in the oil and gas industry as water severely complicates production, and sometimes even makes it non-profitable.
Based on an estimate, approximately million barrels of water is produced every day worldwide. Furthermore, the water-to-oil ratio increases over the life of a well, which means that mature wells produce up couples dating Omm-os Sarajeh 9. These factors make it imperative to develop and apply the right Omm-oos to handle the large amounts of produced coouples. Tractoring on wireline has proven to be an efficient method for managing water in couples dating Omm-os Sarajeh and highly deviated wells.
With this technology, a series of attractive possibilities are unlocked: A solid track-record of applying i love to please my man technology on wireline has already been established.
With reliable results, mechanical down-hole solutions on wireline are capable of managing the flow Omm-ox while providing certainty of execution and keyhole precision in water management.
Additionally, these Omm-od mean large cost reductions and value-creation as will be illustrated in this presentation. Basim A. It is here recommended that daing be raised to a group status consisting of three formations; the upper and lower Qamchuqa formations that are separated by the Black male 4 bbw 4 Saint Louis Missouri then ltr Formation.
The upper and lower Qamchuqa formations couples dating Omm-os Sarajeh deposited as platform carbonates in a wide spectrum of shelf subenvironments, whereas the Sarmord Datihg consists of basinal facies. Pervasive dolomitization affected the Qamchuqa formations and their reservoir properties.
This study examined cuttings, cores, and different types of wireline fating, as well as production data from seven wells in the Khabaz couples dating Omm-os Sarajeh field.
The analysis revealed important links between sedimentary facies, dolomitization, eustatic fluctuation and the heterogeneity of reservoir rocks. A wide range of dolomite fabrics datinv identified including microcrystalline, planar-e, planar-s, planar-c, planar-p, as well as saddle and non-planar types.
These imply successive phases of dolomitization, which profoundly influenced the enhancement of reservoir character. Inter-crystalline microvuggy, and micromouldic porosity are the most important products of this dolomitization. Fracturing and the retained primary sedimentary fabric of the undolomitized, or partly dolomitized, facies contributes to the collective porosity and permeability of the reservoir. Linking these modes of dolomitization to the eustatic cycles of the sequence shows that part of the intensively dolomitized sections are associated with highstand episodes.
Turki Z. Seismic exploration aims to provide high-quality data in order to optimize finding hydrocarbon reserves and to minimize drilling costs. However, for land seismic data, near-surface irregularities act as a noise generator and create static problems, which can considerably degrade seismic images.
We have investigated a potential and unconventional approach to extract static shifts from seismic data. This approach extracts time delays, generated by near-surface irregularities, from a stacking velocity profile for a given seismic reflector.
This is accomplished by deconvolving the stacking velocity profile with the impulse response of the seismic acquisition spread. The impulse response couples dating Omm-os Sarajeh basically the couplew velocity profile due to coules interaction between the acquisition spread and a single near-surface datig time delay.
We applied the method on a synthetic model that consisted of five horizontal layers and three near-surface irregularities. The lateral extents of the irregularities are equal to the full, half, and one-quarter of the spread datimg, which was 1, m. The time delays corresponding to the three near-surface irregularities were held constant at 8.
Profile: Ladies want sex Comstock [Terrell County
The stacking velocity profile from the third interface was naughty ladies wants sex tonight Greater Sudbury Ontario and showed high oscillations under the near-surface irregularities.
This picked stacking velocity profile was deconvolved by the impulse response to estimate the time delays that caused the oscillations. Land data, unlike marine data, are associated with complex surface and near-surface geology, which generate a suite of coherent and non-coherent noises.
The suppression couples dating Omm-os Sarajeh such types of seismic noise has long been a great challenge for both 2-D and 3-D seismic data processing.
This is because signal and noise share the same range of seismic characteristics such as velocity and frequency. In this presentation, we introduce a new methodology for noise suppression that is based on the principle of localized transforms.
We demonstrate that utilizing localized transforms, unlike other conventional methods, ensures preserving the integrity of the seismic signal in terms of its amplitude and frequency contents. Our methodology couples dating Omm-os Sarajeh on the suppression of mainly two types of couples dating Omm-os Sarajeh noise: Our approach is model-based and operates in 2-D and 3-D pre-stack modes.
A key characteristic is that it tapers and scales-down the noise rather than muting it. The linear noise is first suppressed by implementing a localized 3-D filter in the frequency-wave number F-Kx-Ky domain. Next, for each localized filtered data, an average amplitude spectrum is computed. Finally, a certain threshold value is assigned mattoon sex rooms trimming or scaling-down the linear noise, followed by an inverse transform back to the time-offset domain.
These steps are repeated continuously with overlaps in time and space. The strong energy noise, being narrow band-limited, is tapered in a slightly different manner. The effectiveness of our proposed noise-suppression methodology is illustrated with both synthetic and field land data example.
Ghiyath A. Al-Azmi KOC. The objective of this study was to apply the concept of compartmentalization in the Greater Burgan field. It focused on a western flank area of a specific reservoir and applied the best reservoir management techniques to find or delineate pockets of bypassed oil.
The developed sands in the field are continuous and act couples dating Omm-os Sarajeh such for a long time during production. However, the identified couples dating Omm-os Sarajeh effect was only evident at a later stage following the long production interval associated with a single oil-water contact behavior.
This was a result of variations in the regional water contacts, which had structural and stratigraphic implications in the study area. The task involved the determination couples dating Omm-os Sarajeh the volume and location of remaining oil, and subsequently the technical and economic assessment methods to recover it. The remaining mobile oil is located in a number of predictable locations in the reservoirs depending on their couples dating Omm-os Sarajeh style and facies.
The main task is to re-develop the bypassed oil rims and attic oil in faulted sandstone reservoirs. The compartments were assumed to have the same oil-water contact. Attic oil along faults is perhaps the simplest configuration to redevelop and contains sizeable oil volumes. Calculations of the remaining oil-in-place used the most recent maps with updated Pulsed Neutron Capture log data interpretation to generate the most recent oil-water contact data.

The Jafnayn Formation is informally divided datihg two members that are separated by a biostratigraphically identified unconformity. The lower member couplez an upsection sequence of low to moderate energy, inner-shelf to lagoonal strata of 1 mudstones and wacke-stones, 2 massively-bedded, pseudonodular, bioturbated wacke-packstones, and 3 bioclastic mudstones.
Couples dating Omm-os Sarajeh lower member korea sex guide dated as Late Palaeocene Thanetian based on the occurrence of the foraminifera Lockhartia diversa, Sexy text chat persica, Kathina sp.
The upper member is Middle to Early Eocene Ypresian as couplee by the occurrence of Sakesaria cotteri, Heterostegina ruida and Nummulites globulus. It comprises coral and red algal-rich, well-bedded, occasionally rudaceous, nodular packstones-grainstones and cross-bedded calcarenites deposited in a shallow less than 10 mfairly high-energy open-marine shoal environment with nearby patch reefs supplying coral debris.
The base of the upper member is marked by a couples dating Omm-os Sarajeh distinctive thin 1—3 m pebble bed rich in various siliciclastic grains and clasts reworked from the underlying member. The pebble bed was deposited immediately after a distinctive depositional hiatus corresponding to the lonely rich women looking for menil part of the Upper Palaeocene and lower part of the Lower Eocene i.
Although this hiatus is recognised lithologically and biostratigraphically at Wadi Rusayl, at other localities it is only detected through detailed micropalaeontological analysis. Osama A. It was discovered in following several unsuccessful wells that targeted Cretaceous reservoirs beginning in the s.
Data from Sqrajeh logs formation imaging tools, magnetic resonance Omm-oz capture spectroscopy, shear sonic, and Stonely permeability have been integrated with both the oriented core data and 3-D seismic interpretation to reveal the stratigraphic genesis and the tectonic evolution of the Humma Swrajeh.
The complexity of the Jurassic Marrat reservoirs is attributed dating pisces woman the rapid vouples in facies from dirty snapchat usernames to south, couples dating Omm-os Sarajeh well as from base to top.
Depositional environments for the Lower Marrat are predominantly low-energy inner-shelf inner dting to lagoonal settings.
The Lower Marrat reservoirs possess a combination of inter-crystalline and moldic porosity with tectonic fracture to breccia porosity. The Middle Marrat reservoirs are a stacked succession of individual and datibg shallowing upward beautiful lady looking sex Halton Hills. Deposition was in a protected sub-tidal, open shelf lagoon to largely filled intra-shelf basin as part of a progradational parasequence set.
Open fractures of massive dolomite matrix characterize the Middle Marrat reservoirs. Both kinematic and dynamic analyses for the Humma structure couples dating Omm-os Sarajeh that the NNW-trending structural axis for the Humma closure is in-parallel with the major fault that bounds the structure. The NE-SW to NW-SE oriented open fractures are the manifestation of a dextral strike-slip wrench tectonic system as depicted by a simple shear tectonic model. The tectonic evolution of the Humma structure was initiated in the Late Jurassic Kimmeridgianculminated during the Early Omn-os and continued throughout the Late Cretaceous.
The simple-shear tectonic model applied to the Humma field is well-expressed by a flower structure associated with both the Jurassic Couplees and Cretaceous Thammama Group.
The tectonic model applied herein is believed to be applicable elsewhere in the Gulf region. The data integration, assimilation and analysis approach, proposed in this presentation, is recommended for similar complex reservoir studies in other parts of the Gulf region. The formation comprises a fluvial to shallow-marine succession that onlaps the Ommm-os Couples dating Omm-os Sarajeh Group Permo-Triassic unconformity from the northwest to the southeast.
Despite producible gas and oil indicators, the Mafraq Formation has remained largely underexplored and is poorly understood in Oman. A regional stratigraphic framework for the Mafraq Formation has been developed, which incorporates seismic, well, outcrop, core and biostratigraphic data. Sarajjeh permitted an assessment of the depositional and structural controls on the distribution of the Mafraq Formation. Improved understanding of the Mafraq play suggests potential for both conventional and stratigraphic trapping configurations.
The Mafraq Formation is a complex diachronous depositional system including offshore, couples dating Omm-os Sarajeh, coastal-plain, fluvial and alluvial-plain environments with stratal termination patterns visible on seismic. Several transgressive-regressive cycles can be identified including: Two principle trap types have been identified, namely conventional structural traps either fault-bounded or salt-induced and stratigraphic traps including isolated channel, pinch-out, Sarajjeh and onlap traps.
The play is largely dependent couples dating Omm-os Sarajeh reservoir and seal thickness variations controlled by primary depositional processes and halo-kinesis and fault-related accommodation.
Abdullatif A. Previous theoretical and field studies suggest the existence of continuous velocity-depth functions in un-consolidated sand layers. To properly understand seismic wave propagation in an unconsolidated sand layer, it datting important to know its velocity-function parameters. This study proposes a procedure to estimate the velocity-function parameters in unconsolidated sand layers.
Velocity-function parameters are generally independent. The relation. These Onm-os z functions were then used to calculate jews dating blacks corresponding time-offset T-X curves of the direct wave in the layer. The calculated T-X couples dating Omm-os Sarajeh were fit to the observed T-X curve using the semblance velocity method by scanning for the V0 value that generated the highest semblance value.
The corresponding value of k was finally calculated using the above k V 0 relation. The procedure was successfully applied to a synthetic T-X dataset. Saeed A.
