Mechanisms of Shale Oil and Gas Accumulation
Description
In recent years, with the change of geological thinking and the progress of horizontal well drilling and fracturing technology, shale oil and gas have been greatly explored and developed in the United States, Canada, Australia, China, and other countries. Explored basins include the Appalachain basin, Illinois basin, Fort Worth basin in North America, Sichuan basin, Ordos Basin, Junggar Basin in China, Beetaloo basin, and Perth basin in Australia Basin, both of which show good exploration prospects.
However, while drilling a number of high-yield shale oil and gas wells, there are also some shale oil and gas wells with low production or even no oil and gas. In the same exploration areas, the oil and gas production difference is also large. How to reduce the exploration risk and define the favourable exploration target is an urgent problem to be solved. With the increase of well data and the application of advanced analytical and testing methods, the research on shale sequence, sedimentation, reservoir, and shale oil and gas accumulation can be further deepened. Moreover, with the development of this research, scholars have begun to realize that the deep fluid activity in the crust has an important impact on the organic matter enrichment, shale reservoir, and shale oil and gas accumulation, but at present, the research in these fields is insufficient.
This Special Issue aims to collate articles relating to shale sequence, sedimentation, fine characterization of shale reservoirs, shale oil and gas accumulation mechanisms, and the influence of deep crustal fluid activities on organic matter enrichment. Original research and review articles are welcome.
Potential topics include but are not limited to the following:
- Sequence division and sedimentary characteristics of shale
- Accumulation mechanism of organic matter
- Fine characterization of shale reservoirs
- Sealing capacity of shale reservoirs
- Studies on shale gas preservation conditions
- Shale oil and gas accumulation mechanisms
- The influence of deep crustal fluid on organic matter enrichment, shale reservoirs and shale oil and gas accumulation
