Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, February 4–6, 2020
Paper Number: SPE-199753-MS
... Abstract Unconventional reservoirs suffer from an ultra-low permeability, causing their drainage area to be limited to tens of feet. An efficient technique that can be used in combination with conventional hydraulic fracturing to increase the drainage area is pulse power plasma. In this study...
