Analcime laminae in lacustrine shale oil reservoirs and its significance for hydrocarbon migration and accumulation, by Junran Wang, Chao Liang, Shunyao Song, Yingchang Cao, Keyu Liu, and Fang Hao. Based on detailed petrographic investigation, in situ element measurement, and organic geochemistry analysis, the significance of analcime for reservoir modification, hydrocarbon migration, and accumulation was investigated in the Kongdian Formation of the Bohai Bay Basin. The synergistic interplay between distinct analcime morphologies and organic constituents constitutes a critical control on premium reservoir formation.

A petroleum system analysis of anomalous Lower Pennsylvanian oil field, Pottsville Group, Appalachian Basin, by Ronald L. Martino, Kenneth Marcum II, Charles Sorden, and Carrie Kidd. The Greasy Ridge oil field of Ohio is an anomaly because of its accidental discovery and geographic isolation from other oil fields in the Lower-Middle Pennsylvanian Pottsville, New River, and Lee Sandstone play. This study examines its origin within the context of the Devonian shale-middle-upper Paleozoic petroleum system using a robust data set, including geophysical well logs, cores, seismic profiles, and nearby correlative outcrops.

Timing of porosity loss and hydrocarbon charging of the Ordovician carbonate reservoirs in the Shunbei oil field, Tarim Basin, northwestern China, by Bin Wang, Xiaowen Guo, Zicheng Cao, Tiago M. Alves, Yongqiang Zhao, Ze Tao, Jiaxu Chen, and Yi Yang. The Shunbei oil field of the Tarim Basin comprises important Ordovician carbonate reservoirs associated with strike-slip faults. Here, strike-slip fault zones contain sufficient space to accumulate significant hydrocarbon volumes. The research concludes that petroleum accumulation in the carbonate reservoirs is mostly associated with the strike-slip faults, resulting from new reservoir pore spaces.

Subsurface mapping of central Israel: Implications for hydrocarbon exploration, by Yuval Bartov, Stepan Vygovskiy, and Yuri Volozh. This paper presents the results of the reprocessing of extensive seismic data culminating in enhanced subsurface imaging of the Negev of Israel. A set of structural maps has been produced, significantly improving the understanding of the deeper sedimentary sections of the region. The analysis highlights similarities between the Judea graben (Israel) and the Palmyra trough (Syria), suggesting the presence of a late Paleozoic basin.
