evaluation of polyacrylamide gels with accelerator

Evaluation of polyacrylamide gels with accelerator

The property of polyacrylamide gel with accelerator ammonium salts served for ultralow to low temperature reservoirs is sensitive to many variables. The viscosity of the HPAM gel with ammonium salt initially decreases and then increases with time pass at room temperature, which is beneficial for pumping at surface condition.
