Summary: This study uses one-dimensional basin modelling to examine the hydrocarbon generation and expulsion history of Upper Jurassic source rocks in the Sab'atayn Basin in Yemen. The modelling results reveal significant subsidence and uplift events that have had a notable impact on heat flow distribution and hydrocarbon generation.

Summary: This study quantitatively analyzed the hydrocarbon source rock potential of the Triassic-Jurassic of Mandawa Basin using the g-GMDH method, machine learning, and geochemical analysis. The proposed g-GMDH model showed better performance than other models in predicting geochemical log profiles. The hydrocarbon source rocks in the basin were found to be of fair to very good quality, containing mixed kerogen types II and III. This research provides an improved technique for evaluating source rocks in frontier basins.

Summary: The hydrocarbon source rocks in the Nanpu Sag were studied, and it was found that the Es-3 (2) section mainly consists of type II2, while the Es-3 (4) section mainly consists of type II1, with good organic matter type and high maturity. The multiple linear regression method is more effective than the ΔlgR method in predicting hydrocarbon source rocks in this area. The hydrocarbon source rocks in Es-3 (1) have generally low TOC and hydrocarbon potential, while the high value areas of TOC and hydrocarbon potential in Es-3 (4) are mainly concentrated in the Shichang sub depression.

Summary: The eastern Tunisian margin is an important petroleum province with oil and gas shows and accumulations in Upper Cretaceous carbonates. The basin's geodynamics and the migration of hydrocarbons are closely related to the platform and basin blocks. The volume of expelled hydrocarbons from the source rocks is much greater than that found in the drilled anticlinal axis, indicating the presence of unaccounted-for hydrocarbon volumes trapped along fault branches, unconformities, pinchouts, and progradational and reefal system tracts sequences.

Summary: The study presents a new organic geochemical evaluation for a petroleum source rock in the Southeastern Sabah basin, focusing on the Kalabakan, Tanjong, and Kapilit Formations. Results show that the Kapilit and Tanjong Formations have higher hydrocarbon generation potential compared to the Kalabakan Formation. The three formations exhibit a wide range of maturity, influenced by tectonism and sediment development in the basin.

Summary: This paper discusses the effect of source rock-reservoir assemblage on hydrocarbon expulsion, molecular composition, and thermal maturity in a hybrid shale system. The study conducted on core samples from the Chang 73 sub-member of the Triassic Yanchang Formation in China shows that chemical fractionation exists in the source rock-reservoir assemblages at different scales. The molecular composition behaves differently in the lithofacies and lamina scale reservoirs, with lower EC21_/EC22+ in the lithofacies reservoir. The thermal maturity indices show similar trends as EC21_/EC22+. The research also suggests that oil is more easily expelled from organic-lean lithofacies.

Summary: This study on source rock samples from the upper shale unit in the Lower Goru Formation of the Lower Indus Basin found that the samples have fair source rock potential and may be considered as a good candidate for hydrocarbon generation perspective. The study also revealed that the organic matter in the samples is mainly terrestrial and the depositional conditions vary from anoxic to dysoxic. Various maturity parameters showed mature organic matter input and peak oil-window for the samples, indicating an increase in thermal maturity with depth.

Summary: Based on the latest drilling and analysis, the study clarifies the sub-source hydrocarbon accumulation characteristics and establishes the hydrocarbon accumulation model of the Permian reservoirs in the Jinan Sag. The results show that there are large-scale reservoirs developed in multiple formations, with good regional seals and different reservoir-forming assemblages. The presence of chlorite film and microfractures effectively increase the sub-source pore space, improving the efficiency of hydrocarbon accumulation. The study also reveals the three periods of oil accumulation and the conditions for forming large reservoirs in the thrust belt. The findings have guidance and reference significance for oil and gas exploration in the Jinan Sag and similar areas.

Summary: The identification of preserved deposits of subaerial catastrophic mass-wasting requires assessment of deposit fabrics. A 95 m thick megabed in the Gosau Group of the Alps is interpreted as a vestige of a subaerial rock avalanche deposit, characterized by poorly sorted clast-supported sediment with crackle, jigsaw, and mosaic fabric. The megabed displays planar parallel stratification and suggests an incised valley propagation. This is the first identification of a subaerial rock avalanche deposit in the Gosau Group.

Summary: The nature of pore systems in the Powder River Basin's Mowry and Niobrara shales plays a critical role in evaluating production potential and finding sweet spots. Understanding variation in pore type, size, and connectivity, as well as their relationships with mineralogy and fabric, helps determine prospectivity in different parts of the basin. Imaging techniques reveal the presence of migrated organic matter and its impact on wettability alteration, controlled by clay morphology and mineral grain framework. Carbonate content is a good indicator of reservoir quality in the Niobrara, while high recrystallized microquartz content is associated with the best reservoir intervals in the Mowry.

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.

This study investigates the metallogenic characteristics and enrichment process of oilfield brines from the Jianghan Basin, central China using chemical and multi-isotope data. The results suggest that lithium enrichment in these brines is the result of interaction with clastic host rocks and dilution by meteoric water.

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.
