Opening of Bedding-Parallel Fractures in the Shale Oil Reservoirs of the Paleogene Funing Formation, Subei Basin, China

Energies
Bedding-parallel fractures represent a crucial flow-path network in shale oil reservoirs, yet their timing of opening and driving mechanisms remain subjects of long-standing debate. This study investigates the origin and opening mechanisms of bedding-parallel fractures within the Paleogene Funing shale oil reservoir of the Huazhuang area, Subei Basin ...
