DOI: 10.1021/acsomega.3c00543
Abstract: During hydraulic fracturing, the oxic hydraulic fracturing fluid physically and chemically alters the fracture surface and creates a “reaction-altered zone”. Recent work has shown that most of the physicochemical changes occur on the shale fracture… read more here.
