Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, February 1–3, 2022
Paper Number: SPE-209130-MS
... Abstract It is now well established that production from horizontal wells with multi-stage hydraulic fracture stimulations performed through plug and perf completions is highly variable along the length of the wellbore. In addition to the elements of the completion design, such as fluid...
