Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1602
... ABSTRACT: When a hydraulic fracture is poorly supported by sub-monolayer proppant, acid treatment of a brittle, carbonate-rich shale fracture may be able to reduce proppant crushing and fracture closure by making the rock matrix more ductile. To test this hypothesis, a series of laboratory...
