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: Based on marine geological research milestones, the late Jurassic Campeche salt basin in the southern Gulf of Mexico is related to the late Middle Miocene to Recent geological structures. The study reconstructed the geometry of the top of the Paleozoic basement and base-salt topography using shipborne magnetic data and 28,612 km of pre-stack, depth-migrated, 2D seismic data. The Campeche segment of the Gulf of Mexico outer marginal trough, which is 40-55 km wide, marks the limit of the northwest-directed passive margin foldbelt.

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: The study utilized Gas Chromatography-Mass Spectrometer (GC-MS), chloroform asphalt A, and carbon isotope measurements to determine hydrocarbon migration pathways in the Wucaiwan region, Junggar Basin, China. Various geochemical analyses were conducted to investigate oil sources, natural gas type and distribution, as well as hydrocarbon migration periods. The study revealed that petroleum primarily migrated vertically along faults, sandbodies, and unconformities, with limited lateral migration due to reservoir porosity and caprock composition.

Summary: The study identifies two major detachments within the northeastern Sichuan Basin thrust belt, with the dark gray shales in the lower Silurian Longmaxi Formation being a potential source rock. The stratigraphic succession is divided into three structural intervals, with the lower structural interval being a good candidate for hydrocarbon exploration.

Summary: The study conducted three-dimensional basin and petroleum system modeling in the Iranian sector of the NW Persian Gulf to investigate hydrocarbon generation, migration, and accumulation. The results show that the Zagros orogeny plays a major role in controlling burial and thermal evolution as well as hydrocarbon migration and accumulation in the region. The direction of hydrocarbon migration and accumulation is mainly controlled by the kinematics of the structural highs.

Summary: The Baltic Basin is famous for its Paleozoic hydrocarbon reservoirs. This study investigated the hydrocarbon migration pathways and escape structures from Paleozoic source rocks to the seafloor using multibeam, sediment sub-bottom profiler, and seismic reflection data. The results identified a hydrocarbon migration system in Silurian and Devonian strata, with migration occurring beneath sealing layers, along faults, and through seafloor escape structures. The migration trend was directed updip towards the Gotland Depression. The study also highlighted the importance of the regional geological setting and iceberg scouring in facilitating hydrocarbon migration.

Summary: This study investigates the origin and migration characteristics of petroleum in the northeastern part of the Baiyun Depression in the Pearl River Mouth Basin. The study finds that petroleum mainly originates from the Enping Formation source rocks and migrates through active faults and sandstones. The episodic petroleum migration is controlled by fault activities, with different factors influencing the migration behaviors.

Summary: The Borno (Chad) Basin is an intra-cratonic rift basin located at the southwestern terminal of the West Africa Rift System. Despite reported low petroleum potential, oil seepages have been found from its oldest stratigraphic unit, the Bima Sandstone, posing challenges in classifying the basin's petroleum system elements and predicting the origin of the oil seepages. Structural analysis and petroleum system modeling have been employed to investigate the structural and hydrocarbon evolution of the basin, revealing a lack of key petroleum system elements due to uplift during the Late Cretaceous, causing sediment diversion and hindering conventional hydrocarbon entrapment.

Summary: Inversion of the Lower Saxony Basin has led to the formation of large-scale broad antiforms, where Germany's largest gas accumulations can be found. However, in some areas, exploration and production wells have failed due to missing reservoir or wet conditions despite drilling in the topmost position of the trap structure. Seismic interpretation shows that the topmost Ca2 reservoir has undergone lateral shear due to oblique inversion-related collision, resulting in the redistribution of Permian Zechstein salt. This shear occurred along a thin Zechstein salt decollement, leading to the detachment of large intra-salt gas reservoirs and leaving behind areas without Ca2 reservoir. This kinematics triggered gas leakage from the Ca2 reservoir, as evidenced by methane-rich fluid inclusions in tectonic veins and stylolites. This study establishes criteria for identifying gas leakage and reservoir presence in inverted settings, providing valuable information for pre-drill risk assessments.

Summary: Chemical analysis data was used to study the properties of liquid fluids in the oil-bearing system of the Wuliyasitai southern sag in the Erlian Basin. The stable carbon isotope (δC-13) values of hydrocarbons indicated a biased lacustrine algal input. Gas chromatography-mass spectrometry was employed to examine the morphological characteristics of various organic compounds. The research findings suggest that water washing, crystallization, and wax precipitation are common occurrences in oil samples, and the salinity of formation water and the abundance of characteristic biomarkers can provide insights into the ancient water body's salinity as well as the hydrocarbon storage environment.

Summary: In situ gamma radiation measurements were conducted to calculate the radiogenic heat production of sedimentary and igneous rocks in the Sabinas Basin of northeastern Mexico. Most of the studied rocks showed low heat production, while a small percentage exhibited moderate and high heat production rates. The high heat production in sedimentary rocks was related to the content of quartz, K-feldspar, clay, and the presence of deep faults, whereas the heat production in granodiorites was associated with the content of K-feldspar, sphene, zircon, and apatite.
