Total organic carbon (TOC) enrichment and source rock evaluation of the Upper Jurassic-Lower Cretaceous rocks (Barents Sea) by means of geochemical and log data

Seal characterization and integrity in uplifted basins: Insights from the northern Barents Shelf

“…However, in the study area there is a lack of direct TOC data. To increase confidence in the correlation of we have used Passey's method (DlogR), which uses acoustic and resistivity data to identify TOC and has also had success in the Barents shelf (Cappuccio et al, 2020). Fig.…”

Gas–Source Comparison and Hydrocarbon Generation and Expulsion Histories of the Main Source Rocks of the Middle Jurassic Shaximiao Formation, Western Sichuan Basin

“…The Shahejie Formation of the Qingshui subsag, Liaohe Depression, Permian in the western margin of the Songliao Basin, and the Yanchang Formation of the Ordos Basin are all near-source accumulation, − indicating that the study of source rocks is very important for natural gas exploration. Hence, determining the origin of natural gas, , revealing the relationship between gas sources, − and clarifying the characteristics of hydrocarbon sources , can offer a scientific foundation for the study of the distribution pattern of oil and gas systems, the establishment of reservoir accumulation models, and the search for favorable areas.…”
