Volume fracturing technology of deep shale gas in southern Sichuan

open access: yesYouqicang pingjia yu kaifa, 2021
Due to the deep buried depth(3 500~4 200 m), high ground stress, high ground stress discrepancy(7 to 17 MPa), low reservoir brittle(< 0.5)and the undeveloped natural fracture, the hydraulic fracture of Weirong deep shale gas face the problems of high ...

Development of an improved numerical model for fracture propagation in hydraulic fracturing of low-permeability formations using FracproPT software

open access: yesUnconventional Resources
The primary technologies employed to access unconventional resources today are horizontal drilling and single or multi-stage fracturing. Micro-seismic data frequently corroborates that hydraulic fracturing in shale reservoirs generates intricate fracture
