Mechanism of multi-stage sand filling stimulation in horizontal shale gas well development
Fracturing operations in shale gas reservoirs of the Sichuan–Chongqing area are frequented by casing deformation, failures in delivery of mechanical staging tools and other down-hole complexities. In addition, limitation in volumes of tail-in proppant in

Complex Fracture Networks Prohibit Safe Fracturing Fluid Recovery
ABSTRACT The recovery of fracturing fluid (HF), necessary for subsurface energy production and carbon storage, is generally low, raising concerns about HF fate in the subsurface and its potential to contaminate water aquifers. This study examines the migration of fracturing fluid and tracks its distribution in fractured reservoirs using a two ...
