Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, March 22–25, 2021
Paper Number: SPE-204412-MS
... Abstract While assessing post-hydraulic-fracture perforation growth using solid-state, high-resolution acoustic imaging tools, it was noted that plug failures were occurring at a high frequency. Though plug failures can be observed from hydraulic fracture surface pressure and flowrate data, the...
