CoastaLube CT®


Coil Tubing Fluid Additive

Exceptional Lubricity Using Sun’s PAO Technology



SUN's CoastaLube CT® is a high performance pipe on pipe lubricant for brine and water-based coil tubing fluid systems, utilizing a polyalphaolefin (PAO) synthetic hydrocarbon base. Environmentally safe, CoastaLube CT® is a U.S. EPA acceptable, environmentally safe lubricity additive.  PAO's are man-made and contain no aromatics or have the adverse properties of traditional mineral and diesel oil based products.

Sun's CoastaLube CT® enhances the performance of the CT fluid by preferentially placing a thin film coating on the coil and casing which acts as a boundary layer lubricant in high temperature and pressure applications. CoastaLube CT® is readily dispersible and compatible with fresh and saltwater-based systems.

CoastaLube® has proven successful in solving problems related to kick-off point difficulties and other extended reach applications.
