Sample preparation Experimental section The Qingshankou Formation is characterized by high clay mineral content and well-developed laminae. For such a shale oil reservoir type...

... Abstract CO 2 fracturing and flooding have become key technologies for increasing shale oil recovery. However, for shale reservoirs with high wax content, the production data from Daqing oilfield indicate lower later-stage recovery rates and a significant occurrence of wax deposition during...

... As conventional oil resources are gradually depleted, the global demand for energy continues to rise. Shale oil, as an unconventional oil resource, has increasingly attracted attention ( Shiyi and Qiang 2018 , Shonkoff et al. 2014 , Liang et al. 2023 ). Particularly in the United States...

... By the increase in proved reserves of unconventional oil and gas, tight oil is becoming one of the primary research targets as the revolution of development interest shifts from conventional reservoirs to unconventional ones. As an important unconventional oil resource, shale oil, which owns...

... Abstract Shale reservoirs in lacustrine sedimentary basins represent crucial sectors for shale oil exploration and development. Given their mixed sedimentation, complex origins, and pronounced heterogeneity, the stratigraphic reservoirs exhibit diverse spatial types. Identifying...
