Summary: This study applies the sequence-stratigraphic method to assess the containment potential and risk of geological carbon sequestration. The findings suggest that clay-mineral aggregates provide the most consistent excellent seals, while more distal rock facies have lower containment capacity. The geometry and extent of favorable top seals are influenced by the basin type and sediment delivery.

Summary: The Zaysan Basin in northeastern Kazakhstan is a petroliferous basin closely related to the Central Asian Orogenic Belt. The complex hydrocarbon migration and accumulation processes in the basin reveal differences in oil characteristics in different reservoirs, indicating an origin from source rocks deposited in anoxic brackish-saline environments with low maturity and impact of biodegradation processes. Two stages of oil charge and one stage of gas charge were identified, with the oil mainly originating from the first oil charge.

Summary: This study analyzed the petroleum system of the Bannu Basin in Pakistan, a foreland basin of the Himalayan fold and thrust belts. The study divided the area into three zones and integrated seismic and well log data. The results showed higher sedimentation levels and abrupt sedimentation due to Himalayan orogeny. Potential source rocks and local faults were identified as potential traps for hydrocarbon preservation. Specific formations were identified as potential reservoir rocks in different zones. Post-Miocene sedimentation was found to be a significant event for hydrocarbon generation and accumulation.

Summary: The hydrocarbon potential of the UAE-Oman mountains fold-and-thrust belt (FTB) has not been extensively studied, resulting in a poor understanding of the petroleum systems in this region. This study aims to address this knowledge gap by evaluating the petroleum system of the FTB using basin modeling approaches and correlating hydrocarbon occurrences with their source rock. The findings identify the Silurian, Upper Cretaceous, Paleocene-Eocene, and Oligocene formations as the primary source rocks in the study area. The Cenozoic source rocks exhibit variable Total Organic Carbon (TOC) content and expulsion efficiency, with increasing maturity towards the north. Late Cretaceous and Oligocene-Miocene compressional events influenced the present-day distribution of maturity, and hydrocarbon expulsion from the Silurian source rocks initiated during the Middle-Late Jurassic.

Summary: This study conducted a detailed analysis of the Qiulitage fold belt in the Kuqa foreland based on open-access DEMs and field work. The results indicate that the fold belt consists of six morphological units and has undergone interactions during vertical growth and lateral propagation of the folds. The structural evolution of the fold belt has significantly influenced the development of major rivers and minor rivers.

Summary: The structural analysis and temporal evolution of the Dehdasht Structural Basin in the Central Zagros have been defined through constructed cross-sections and 2D sequential restoration, revealing trap formation timing and hydrocarbon potential. The study suggests that large-amplitude anticlines near basin margins are the most likely targets for future oil exploration, with possible hydrocarbon generated mainly from the Cretaceous Kazhdumi shale. Additionally, fore-thrusts and caprock erosion control oil and gas seepages on the basin boundaries.

Summary: The petroleum resource assessment obtained from laboratory tests on old core samples tends to underestimate the in situ resources. This study investigates the hydrocarbon loss and restoration by comparing preserved and exposed core samples. It is found that previous studies have severely underestimated the in situ hydrocarbon potential due to factors such as sample crushing and crucible waiting. A new restoration model is proposed to compensate for these losses.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.

Summary: This study employs an integrated depositional and sequence stratigraphic approach to assess the control of diagenesis on reservoir porosity of a hybrid-energy delta system. The study focuses on the Barik Formation in the Haushi-Huqf region of Central Oman, which represents a highstand system tract of a hybrid-energy delta. The assessments reveal that the reservoir porosity is controlled by various degrees of diagenetic processes, including mechanically infiltrated clays and kaolinitization of silicate grains.

Summary: Due to the lack of deep wells in the broader region, studying mud volcanic deposits can improve the geological understanding of the Mediterranean Ridge. In this study, biostratigraphic and geochemical analyses were performed on mud breccia deposits from five Mud Volcanoes in the central MR. The results indicate the origin of these deposits and provide insights into the source rock potential. Seismic data is also used to determine the distribution of major lithostratigraphic formations.
