Drilling Polymer

Drilling polymer is a high molecular weight polymer that controls fluid loss and increase drilling mud viscosity. Drilling polymer emulsion contains copolymer and is used generally as a borehole stabilizer to prevent reactive shale and clay from swelling and sloughing. Drilling polymer emulsion is also added to low-solids drilling uids to increase lubricity, uid viscosity, and to improve carrying capacity of air/foam injection uids.

Chemtex Speciality Ltd.'s maufactures PHPA based drilling polymer and Polugrol based drill polymer. Each polymer is used for a specific application, maintaining viscosity in solid free drilling fluid and as bentonite extender in low solids non-dispersed mud to suspend weight material.
