Poly-Mud S is designed to regulate properties of drilling fluids in broad range of temperatures from 0 to 180ºC. Poly-Mud S contributes to thinning of thickened clay muds, simultaneously reducing the filtration rate by 30 to 50%. It provides an inhibiting effect on argillaceous rocks of reservoir, preventing accumulation of colloidal clay fraction in drilling muds.
Poly-Mud S is compatible with all drilling reagents, and is efficient in broad range of pH values, from 8 to 12. It causes no foaming and does not require any use of defoaming agents.
Recommended concentration of Poly-Mud S in drilling fluid is 0.2 to 2.0%
