Natural fractures are the key factors controlling the enrichment of shale oil. It is of great
significance to clarify the distribution of natural fractures to guide the selection of sweet spots …

Fractures are important to shale gas reservoirs because they can increase the storage
spaces and seepage pathways. In addition, natural fracture systems are important to …

Maximum burial depth of the Permian Fengcheng Formation, which contains significant oil
resources in the Mahu Sag, exceeds 4500 m constituting a deep reservoir. Fractures are …

Under the general trend of stepping-up oil and gas exploration and development in China,

Abstract In southern Sichuan Basin, the main production layers are characterized by deeply
buried, high stress difference, and complex structural conditions. The Luzhou area is far from …

In situ retorting of oil shale requires explosive loading, hydrofracturing or other treatments to
produce the bed porosity necessary for a self-sustaining burn. Fundamental to the …

Fractures play an important role in the formation of shale-gas reservoirs because they can
enlarge the transport channels and aggregation spaces and increase the specific surface …

Fractures play a vital role in the exploration and development of shale oil and gas by
providing effective space for shale reservoirs and significantly improving the fluid flow …
