Exceptional drilling fluid lubricity using SUN’s PAO technology

CoastaLube is a high-performance drilling fluid lubricant for water-based drilling systems, utilizing a polyalphaolefin (PAO) synthetic hydrocarbon base. SUN’S CoastaLube is a U.S. EPA acceptable, environmentally safe lubricity additive with a secondary function of wellbore stability and shale inhibition. PAOs are synthetic and contain no aromatics or the adverse properties of traditional mineral and diesel oils.

  • Reduces torque and drag
  • Minimizes bit balling
  • Decreases friction and wear
  • Minimizes differential pressure sticking
  • Non-toxic
  • Non-sheening
  • Base fluid thermal stability >600°F (315°C)
  • No adverse effect on rheological properties
  • Broad range efficiency
  • Replacement for diesel, mineral-oil-based fluids or other synthetic base lubricant additives
  • Meets EPA discharge requirements
  • No effect on LC50 value of active fluid system

CoastaLube enhances the performance of drilling mud in low-pressure situations by coating the formation and drill string as well as acting as a boundary layer lubricant in high temperature and pressure applications. CoastaLube is readily dispersible and compatible with fresh and saltwater-based systems.

CoastaLube has proven successful in solving problems relating to angle building, angle dropping, kick-off point difficulties, and mud motor drag.
