Experimental investigation of friction reducer effects on the microstructure and permeability of Longmaxi formation gas shale

Experimental investigation of friction reducer effects on the microstructure and permeability of Longmaxi formation gas shale

Abstract This study proposes a novel method to investigate the effects of friction reducers on the microstructure and permeability of gas shale, using the Longmaxi formation as a case study. By combining high-pressure mercury injection (HPMI) data, the pore size distributions (PSDs) and permeability...
