Polyanionic Cellulose PAC R Oil Drilling API Standard
PAC-HV has good heat stability, salt resistance and strong antimicrobial properties. Polyanionic Cellulose can effectively reduce the amount of all kinds of oil or gas water base drilling fluid filtration, and can improve and stabilize the drilling fluid viscosity, improve the cleaning ability and stability of the drilling fluid. Poly Anionic Cellulose PAC also helps in controlling the loss of fluid to the formation, which can reduce the effectiveness of the drilling process and potentially damage the formation.Oil Drilling Grade CMC can also help to stabilize shale formations and prevent the disintegration of the drill hole.
