2.2. Synthetic flowback water. Synthetic flowback water was obtained by reacting the synthetic fracturing fluid with 25 g/L shale at 80 ℃ and 83 bar for 24 h simulating downhole conditions encountered in natural gas reservoirs. The variation in these conditions across different gas formations can be large , and its impact on polyacrylamide degradation was investigated previously.

Polyacrylamide (PAM) Used As Fracturing Fluid Additive

Polyacrylamide (PAM) Used As Fracturing Fluid Additive Fracturing is one of the main facilities for increasing oil and gas wells. Fracturing is the use of high-pressure pump fracturing fluid injected into the formation, the formation of cracks and the expansion of new cracks and fill proppant, thereby enhancing the permeability of the formation.
