This product is an oil-soluble additive specifically engineered for use in all invert-emulsion drilling fluids to decrease the coefficient of friction.Decreasing the coefficient of friction reduces torque,drag,and the potential of differential sticking in the wellbore.
This product optimizes the performance of oil-based drilling fluids used on ERD wells or wells with complex trajectories that otherwise would be difficult to drill without exceeding the torque and drag limits of the rig.it also is recommended for slimhole applications to increase the effective weight on bit( WOB) and hence ROP.
Applications:
This product should be added at 1% to 3 % concentration by volume depending on the severity of the problem.care should be taken when adding this additive to invert-emulsion systems with high solids as viscosity can increase. Pilot testing is strongly recommended to derermine any effects on the systems rheological properties for all initial applications and subsequent treatments.
