Analysis of Pore Structure Characteristics and Controlling Factors of Shale Reservoirs: A Case Study of the Qing-1 Member in Gulong Sag, Songliao Basin, China

Applied Sciences
The characteristics of shale oil reservoirs, such as low porosity, ultra-low permeability, and complex pore structure, are key factors affecting effective pore space and fluid migration. This study focuses on medium-to-high maturity mud shale in the Qing-

Coupling thermal and maturity histories of the Gulong shale oil reservoir in the Songliao Basin: Insights from vitrinite reflectance and apatite fission track

Unconventional Resources
The coupling relationship between the thermal state and maturation during the geological historical period is critical for shale oil-gas exploration because their present distribution characteristics are not probably the same.
