Summary: This paper studies the sedimentary and diagenetic factors controlling the heterogeneity and petrophysical properties of carbonate reservoir systems. The research findings show that diagenetic processes such as dolomitization play a crucial role in the development of porosity and permeability in reservoir rocks.

Summary: Understanding the development of syn-rift carbonate systems is complex, and their facies distributions can sometimes be difficult to predict due to key factors such as tectonics, eustasy, palaeogeography and climate. The study in SE Dahra Platform demonstrates that synsedimentary faults control reservoir architecture and predict heterogeneous distributions of carbonate facies, with local tectonic deformations and sea-level changes being primary controls on platform geometry and facies distributions.

Summary: This study used high-resolution seismic surveys and shallow drilling to investigate the internal structure and development of Xuande Atoll, an isolated carbonate platform formed since the early Miocene. Five seismic sequences were identified, indicating the platform formation and expansion during the early and middle Miocene, followed by a shrinking stage before the formation of the isolated platform in the middle Miocene. The final shrinking stage in the late Miocene may be attributed to rapid tectonic subsidence and increased terrigenous sediment inputs due to the formation of the semi-marginal sea. The peri-platform area showed a falling sea-level sequence predominantly characterized by mass wasting deposits.

Summary: Carbonate fault-controlled karst reservoirs are unique due to their buried depth and significant heterogeneity compared to other reservoir types. This study focuses on the Shunbei 5 fault zone in the Tarim Basin and presents a 3D architectural model based on various data sources. The characterization of fault-controlled karst reservoirs is essential for efficient development. The study identifies five architectural elements and proposes techniques to predict their distribution.

Summary: This study successfully quantitatively characterized and geologically modeled the fault/fracture-controlled paleokarsts through the establishment of a hierarchical structure and a hierarchical modeling method. The research was validated in the Tahe oilfield and can reflect the spatial structure of fault/fracture-controlled paleokarst carbonate reservoirs.

Summary: A high-resolution reservoir characterization workflow was used to evaluate the off-structure prospectivity of Lower Jurassic complex carbonate reservoirs in the southern part of Kuwait. The workflow integrated sedimentological and petrophysical assessment, 3D seismic interpretation, and seismic stratigraphy to map carbonate geo-bodies and identify vertical and lateral facies changes. The developed integrated sequence stratigraphic framework allowed for a better assessment of accommodation variations and carbonate ecological settings on sedimentary facies development.

Summary: A reservoir module based on the Concept of Storage Zoning (CSZ) has been developed and implemented in the National Hydrological Model-India (NHM-I) to accurately simulate reservoir water levels and spills. The module shows satisfactory results in simulating the Sardar Sarovar dam and the Panchet catchment in India, improving the overall performance of the integrated model. The integrated model can assess the management practices in reservoir-regulated river basins for effective water management.

Summary: Traditional optimization algorithms used for estimating elastic parameters from field seismic data rely heavily on prior knowledge, leading to uncertainties in inversion results. With the development of neural networks, convolutional neural networks (CNNs) have been applied to this task, but the lack of labeled seismic data and diversity in datasets can hinder their effectiveness. The proposed Geological and Geophysical Model Driven CNNs (GGCNNs) model in this study leverages synthetic labeled prestack seismic datasets to incorporate geological information and achieve a balance between inversion accuracy and labeled data size. Applications demonstrate the effectiveness of GGCNNs in predicting elastic parameters with high accuracy and smoothness.
