For many years, Gilsonite has been used in the oilfield as an additive in drilling fluids.Gilsonite, in various grades and formulations, has been used to combat borehole instability problems, provide lubricity, especially in highly deviated holes, and more recently as a bridging agent to combat differential pressure sticking and provide a law invasion coring fluid.
Gilsonite is used in drilling mud fluids and oil well cementing. Gilsonite, in a range of softening points and particle sizes, is a standard ingredient in oil-based drilling muds used in shales and other difficult geological formations.
Asphalt and Road Paving Sector
Gilsonite is used as a performance-enhancing agent for asphalt mixes. Gilsonite-modified paving mixes achieve higher PG grades and incorporate perfectly into the asphalt blend with no need for high shear milling as is the case with many other modifiers.
Gilsonite is combined with coal and other ingredients as an additive in Foundry sands to insure the quality of the molded part by improving mold release and the overall finish of metal castings.
Chemical Products Sector
Gilsonite combines with many other chemicals and materials that take advantage of its unique physical and chemical properties. Binder and coating applications in metallurgical, wood product, refractary and other industries further demonstrate the versatility and usefulness of this remarkable material.
Inks and Paints Sector
Gilsonite Resin is widely used as the primary carbon black wetting agent for black news inks and headset and gravure inks. Gilsonite Resin competes advantageously with petroleum-based hydrocarbon resins, phenolic resins and metal resinates, all of which it can complement or replace to various degrees.
