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

Table 3

(a) Production increase percentage after 1 year corresponding to different refracturing scenarios

Case	Gas flow rate; (10^4 m^3/day)	PIP; (%)	Cumulative gas production; (10^8 m^3)	PIP; (%)
No refracturing	2.651	—	0.6281	—
Case 1	3.539	33.5	0.7087	12.8
Case 2	5.631	112.4	0.8635	37.5
Case 3	6.115	130.7	0.8196	30.5
Case 4	5.754	117.1	0.8855	41.0

(b) Production increase percentage after 7 years corresponding to different refracturing scenarios

Case	Gas flow rate; (10^4 m^3/day)	PIP; (%)	Cumulative gas production; (10^8 m^3)	PIP; (%)
No refracturing	2.151	—	1.1373	—
Case 1	2.191	1.9	1.2647	11.2
