Contact Us About OptiG™


The OptiG mineral is readily dispersible in diesel- and mineral oil-based drilling fluids in which it controls HPHT fluid loss.


OptiG's HPHT fluid loss control effectiveness extends to its softening point of minimum 350°F (177°C). Higher purity grades are available upon request and may extend temperature limitations as high as 450°F (232°C). Grade selection is based upon expected bottomhole temperature.

Treatment Recommendation

Initial concentration range is 2-6 lb/bbl. Clean up of OptiG fluid loss control additive is achieved through aromatic solvents (benzene, toluene, xylene) and in most chlorinated solvents. Follow safe handling and use instructions regarding all solvents.
