Water Quality Evolution-Guided Pilot-Scale Hardness Control of Saline Coalbed Methane Fracturing Flowback Fluids
Hydraulic fracturing of the Benxi No. 8 coalbed methane reservoir produces saline coalbed methane fracturing flowback fluids whose chemistry changes during flowback, creating a moving treatment target for hardness control, scaling prevention and internal oilfield reuse. This study combined time-resolved gas and water m...
