Accumulation mechanism of crust–mantle mixing helium-rich reservoir : a case study of the Subei basin (Eastern China) [PDF]

Helium reservoirs, as an indispensable and scarce strategic resource, can be categorized into two primary origins: crust- and mantle-sourced. Understanding the mechanisms of its formation and accumulation is a crucial challenge in helium exploration ...

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

Quantitative characterization of fault damage zones in shale reservoirs: asymmetric structures and their implications for fluid flow, a case study from the Gulong Sag, Songliao basin

Frontiers in Earth Science
Fault damage zones serve as critical conduits for fluid migration in shale reservoirs characterized by low matrix permeability. Addressing the challenges in quantitatively characterizing fault damage zones in shale, this study takes the Gulong shale in ...
