Prediction of Production Performance of Refractured Shale Gas Well considering Coupled Multiscale Gas Flow and Geomechanics

Table 5

Production increase percentage with different SRV widths of initial fracture.

SRV width of initial fracture (m)	Gas flow rate; (10^4 m^3/day)	PIP; (%)	Cumulative gas production; (10^8 m^3)	PIP; (%)
