Study on Fracture Morphological Characteristics of Refracturing for Longmaxi Shale Formation [PDF]

Geofluids, 2020
Refracturing technology has become an important means for the regeneration of old wells reconstruction. It is of great significance to understand the formation mechanism of hydraulic fracturing fracture for the design of hydraulic fracturing. In order to accurately evaluate and improve fracturing volume after refracturing, it is necessary to understand
