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-

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.

Experimental study on initiation and propagation of hydraulic fractures in stratified shale oil reservoirs

Journal of Petroleum Exploration and Production Technology
The bedding planes of the Gulong shale oil reservoir in Daqing, China are extremely developed, which causes the hydraulic fractures to extend excessively in the horizontal direction while their longitudinal propagation is limited. In order to improve the
