In complex geological areas, the chronology of tectonic fracture formation is pivotal for the
conservation and enhancement of shale gas reservoirs. These fractures, evolving over …

Well-developed natural fractures in the tight gas conglomerate reservoirs of the
northwestern Sichuan Basin, China, are proved to greatly contribute to the porosity and …

The pore structure and oil content of shales have an important influence on the oil mobility
and enrichment. In this study, the lacustrine shale samples from the Qingshankou Formation …

Natural fractures are effective reservoir spaces and the main seepage channel for tight
sandstones, which control the migration, enrichment, and productivity of oil and natural gas …

Maximum burial depth of the Permian Fengcheng Formation, which contains significant oil
resources in the Mahu Sag, exceeds 4500 m constituting a deep reservoir. Fractures are …

Onshore ultra-deep oil and gas resource is abundant, which has become the main area for
exploration and development in the future. Fracture is an important factor affecting the …

Shale oil resources are abundant in the Qingshankou Formation of the Songliao Basin, but
there are significant production differences between wells. Although there are many factors …

The continental shale oil reservoir of Fengcheng Formation in the northern slope area of
Mahu Sag, Junggar Basin, Western China is very heterogeneous in lithology. Thus, the …

Through the study of organic matter enrichment, hydrocarbon generation and accumulation
process of black shale of the Cretaceous Qingshankou Formation in the Songliao Basin, the …

Abstract The Qingshankou Formation is the primary shale oil exploration and development
target in the Songliao Basin, but controlling factors of shale oil enrichment, especially the …
