In recent years, with the maturity of unconventional petroleum geological theory and the advancement of drilling and fracturing technologies, shale oil and shale gas have begun to gain commercial interest in some petroliferous basins of the terrestrial, marine and sea-land transition strata. Development, especially in Permian Basin, Illinois Basin, Appalachain Basin, Fort Worth Basin in North America, and China's Sichuan Basin, Junggar Basin, Bohai Bay Basin, Songliao Basin, and Ordos Basin have shown promising prospects for exploration.
Due to the variations in sedimentary and petrographic facies as well as tectonic evolution, the formation conditions and enrichment mechanisms of shales with various facies (terrestrial, marine, and sea-land transition facies) are also different. With the increased exploration activities, more drilling and logging data become available. In addition, advanced analysis and testing tools for cores are widely used. These allow for more in-depth studies on the formation mechanisms, shale sequences, shale sedimentation, shale reservoirs, shale oil and gas formation and enrichment of the organic-rich shales with different facies, which will facilitate the discovery of new geological theories and understanding.
This Research Topic, focusing on the geological theory related to shale oil and gas in terrestrial, marine, and sea-land transition facies, aims to present the latest research progress on each topic and the application of shale oil and petroleum geological theory in major hydrocarbon-bearing basins. The topics include but are not limited to the following:
• The formation mechanisms of organic matter-rich shale
• The enrichment mechanisms of organic matters in shales
• Shale sequences
• Shale sedimentary characteristics
• Quantitative fine characterization of shale reservoirs
• Analysis of the self-sealing capacity of shale roof and floor strata
• Evaluation of shale gas preservation conditions
• Analysis of shale oil and gas content
• Shale Oil Mobility
• The reservoir formation mechanism and mode of shale oil and gas
