Poly Anionic Cellulose, PAC- LV PAC-HV PAC-RV
PAC in drilling fluid
Polyanionic Cellulose
PAC used as inhibitor and filtration reducer is better, and fluid mud made with PAC can inhibit dispersion and expansion of clay and shale in high-salt media so that sidewall pollution of drill can be controlled. Compared with CMC, PAC has better uniformity of response, with higher degree of substitution, better transparency and excellent resistance to salt and heat. It can create high-volume mud and cause low-volume loss, according to the test of OCMA.
