Simulation Study of Influence of Nano-Confinement Effect on Shale Fluid Phase Characteristics: A Case Study of Gulong Shale Oil

Processes
Songliao Basin hosts abundant shale oil and gas resources, yet the phase behavior of the fluids is still unclear since the confinement effect of the shale reservoir alters the adsorption effect on the pore walls. In this study, molecular dynamics (MD) simulations were employed to clarify this issue.

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
