Sodium Carboxymethyl Cellulose CMC
Sodium Carboxymethyl Cellulose CMC for petroleum drilling: well mud is the necessary condition while drilling. Mud’s gravity, viscosity, thixotropic property and water-loss amount change according to area, depth of well and different mud. CMC can readjust these data while used in mud.
