Development and evaluation of an environmentally friendly water-block-prevention agent for drilling and completion operations in tight sandstone gas reservoirs
Water-block damage during drilling and completion can reduce gas flow in tight sandstone reservoirs because water-based fluids are easily retained in narrow pore throats. In this work, a non-fluorinated environmentally friendly water-block-prevention agent hexadecyldimethyltertiary amine quaternized silicone oil (FSS)...
