... commercial samples. The impact of the PCE and AFS dispersants on the fluid loss of cement slurries achieved from hydroxyethyl cellulose was investigated via static fluid loss and rheology measurements. All PCE polymers improved the fluid loss performance of HEC significantly more than AFS; i.e. they required...
