Research on loss rules of oil and gas in preserved shale cores after open air exposure

Frontiers in Earth Science
There is a large amount of oil and gas loss in traditional conventional core samples. Revealing the rules of oil and gas loss is of great significance for restore the pristine oil content and oil component in the shale.

Pore characteristics of clay minerals in the Qingshankou shale,Songliao Basin, China: unravelling the effects of illitization

Frontiers in Earth Science
IntroductionClay minerals are critical components of lacustrine shale systems, where their associated pores govern reservoir properties. The diagenetic transformation of these minerals, particularly illitization, profoundly impacts reservoir quality, yet
