We present results from reservoir characterization study of a thin bedded sandstone reservoir located in the Cambay basin using 3D seismic data interpretation. The purpose of the study is to estimate formation properties (porosity and water saturation) of the reservoir zones. Our analysis includes horizon interpretation, synthetic seismogram, seismic attributes, petrophysical analyses and incorporating these information into a Static Geocellular Model for determining the initial hydrocarbon in-place which would help in developing production strategies for improved reservoir management.
This paper presents a field scale reservoir characterization for a late Pennsylvanian clastic reservoir at the Farnsworth Unit (FWU), located in the northeast Texas Panhandle on the northwest shelf of the Anadarko basin. The characterization is undertaken as part of a Phase III project conducted by the Southwest Regional Partnership on Carbon Sequestration (SWP). The target unit is the upper most Morrow sandstone bed (Morrow B Sand). Extensive data acquired from FWU was used to improve previously constructed static and dynamic models. The Morrow B reservoir was deposited as fluvial low-stand to transgressive clastic fill within an incised valley. It is predominantly, subarkosic, brown to grey, upper medium to very coarse sands and fine gravels with sub-angular, to sub-rounded poorly sorted grains either planar to massively bedded. It was shown that primary depositional fabrics have less effect than post depositional diagenetic features do on reservoir performance, although subtle variations in deposition may have had some effect on later diagenetic pathways. Three new wells were drilled for the purpose of field infilling and characterization. Cores and advanced wire-line logs from these wells were analyzed for stratigraphic context, sedimentological character and depositional setting in order to better predict porosity and permeability trends within the reservoir. Structural modeling was conducted through the integration of depth-converted 3D seismic data with well log data to create the framework stratigraphic intervals. This information, together with additional core, UBI image logs and an improved hydraulic flow unit methodology (HFU) was used to characterize and subsequently create a fine scale lithofacies based geological model of the field. Core and log analysis allowed subdivision of the target interval into Hydraulic Flow Units (HFUs). The HFU approach enhanced core analysis and was used to elucidate porosity-permeability correlations. This methodology proved to be an exceptional approach to assigning permeability as a function of porosity during petrophysical modeling. The integrated approach of combining seismic attributes with core calibrated facies and the HFU methodology was able to better constrain uncertainty within inter-well spacing and accurately quantify reservoir heterogeneity within FWU. The approach illustrated in this study presents an improved methodology in characterizing heterogeneous and complex reservoirs that can be applied to reservoirs with similar geological features.

Formation evaluation and rock physics are powerful techniques to link the physical properties of rocks and pore fluids measured at boreholes with petrophysical, elastic, and seismic properties at boreholes or faraway from boreholes. However, several sources of uncertainty in the measurements of these properties can affect the strength of this link. A complete statistical workflow is proposed for obtaining petrophysical properties such as porosity, permeability, volume of shale, and water saturation at the well location. This workflow is based on the wireline logs and core plugs and is applied on the lower Jurassic siliciclastic reservoirs of Kohat-Potwar Geologic Province, Pakistan to determine its applicability, the advantages of the new integrated approach, and the value of uncertainty analysis. The linear regression relations are developed between several petrophysically derived parameters measured from core samples and calculated from well logs data. All these parameters are then used as input constraints in rock physics modeling to calculate seismic properties such as bulk and shear moduli, compressional and shear wave velocities etc. A linear relationship is established between porosity and seismic velocities obtained from rock physics model. The well logs predicted rock physics properties such as seismic (P and S-wave) velocities, effective densities and elastic moduli are in close agreement to those measured by using rock physics analysis. Statistical regression analysis revealed significant similarity in the porosity values obtained from geophysical well logs and core samples. The permeability of reservoir intervals show fairly strong linear relationship with the porosity, indicating that the reservoir interval of Datta sandstone is highly permeable and porous thus having large potential of hydrocarbon accumulation and production.
Evaluating the subsurface characteristics of reservoirs is an important part of hydrocarbon exploration and production in sedimentary basins. This process combines geological, geophysical, and engineering data to comprehend the subsurface geology and fluid distribution, determine reserves, and predict the fluid movement in the reservoir. The primary goal of reservoir characterization is to create a precise and dependable model of the reservoir to maximize the production procedure and reduce the associated risks of hydrocarbon exploration and production. This review examines different approach utilized for reservoir characterization in sedimentary basins, including geological, geophysical, and engineering methods. Each method’s advantages and disadvantages are discussed, alongside their uses in different reservoir contexts. The importance of combining multiple lines of evidence to enhance the accuracy of the reservoir models is also examined.

3D Integrated Structural, Facies and Petrophysical Static Modeling Approach for Complex Sandstone Reservoirs: A Case Study from the Coniacian–Santonian Matulla Formation, July Oilfield, Gulf of Suez, EgyptThe Coniacian–Santonian Matulla Formation is one of the important reservoirs in the July oilfield, Gulf of Suez Basin. However, this formation is characterized by uncertainty due to the complexity of reservoir architecture, various lithologies, lateral facies variations and heterogeneous reservoir quality. These reservoir challenges, in turn, affect the effectiveness of further exploitation of this reservoir along the Gulf of Suez Basin. In this work, we conduct an integrated study using multidisciplinary datasets and techniques to determine the precise structural, petrophysical, and facies characteristics of the Matulla Formation and predict their complex geometry in 3D space. To complete this study, 30 2D seismic sections, five digital well logs, and core samples of 75 ft (ft = 0.3048 m) length were used to build 3D models for the Matulla reservoir. The 3D structural model shows strong lateral variation in thickness of the Matulla Formation with NW–SE, NE–SW and N–S fault directio...

Introduction to Islam and Muslim Civilizations: Textbook and Multimedia2022 •
What does it mean to be Muslim? What is the civilizational legacy of a faith practiced by one quarter of humanity? Addressing such questions, this course explores the rich and diverse traditions of Islam and Muslim Civilizations, ranging from history, law, and scripture through artistic expressions, mysticism, philosophy and beyond. The course is structured as an adventure. Each module is called a “Caravan Journey” and units within the modules are “Serais.” In the Muslim world, Serais were bustling stopping places that supported the flow of information, commerce, and people across trade routes through much of Asia, North Africa, and Southeast Europe. Writing about his experience at one such Caravanserai in China (known as a funduq), the famous Muslim traveler Ibn Battutah observed: “China is the safest and best country for the traveller. A man travels for nine months alone with great wealth and has nothing to fear. What is responsible for this is that in every post station in their country is a funduq which has a director living there with a company of horse and foot…. He sends someone with the travellers to conduct them to the next post station and he brings back a certificate from the director of the funduq confirming that they have all arrived. If he does not do this he is answerable for them. This is the procedure in every post station in their country from Sin al-Sin to Khan Baliq. In them is everything the traveller needs by way of provisions, especially hens and geese” (Gibb and Beckingham 1994, 893-894). Similarly, at each of our Serais, we provide our student travelers with all they need by way of provisions, though perhaps no hens or geese. With the guides and guidebooks we make available to them, we enable them to cross all their Serais to then board the next Caravan, safe and sound, certificates in hand. Caravan Journeys include readings and multimedia, pedagogical activities, and assessments. They provide rich, engaging, student-centered experiences for learners. Over forty outstanding content and education specialists, artists, musicians, filmmakers, and expert consultants have assisted me to develop these materials. To the extent possible, the journey represents the dynamic pluralism of Islam and Muslim Civilizations, showcasing diversity in terms of region, history, schools of interpretation, and gender. It incorporates both primary and secondary sources and goes beyond texts to incorporate video, sound, and images. Many living artists and musicians have contributed to the project. The Caravan Journeys in this course about Islam and Muslim Civilizations include: 1. Studying Islam 2. The Quran 3. The Prophet and His Tradition 4. Prophecy 5. Shiʿism and Sufism 6. Ethics 7. Shariʿah 8. Muslim History 9. Heroes 10. Engaging with Others 11. Civil Society 12.
