  • Gilsonite is a naturally occurring glossy black asphaltic, solid hydrocarbon resin with a low specific gravity. It occurs in its very pure natural state in a mineral called Uintaite.
  • Gilsonite, a unique natural hydrocarbon high in asphaltenes and nitrogen compounds, is a granular solid that is fully compatible  with bitumen. It can be melted into hot bitumen, added during the hot-mix manufacturing process, or blended into a preservation treatment
  • Gilsonite is widely used to prevent or cure loss of cement slurry circulation while cementing oil and gas wells.
  • Gilsonite uses a physical process to stabilize shales rather than the chemical process most widely used in the industry. The mineral, when added to a drilling fluid system, would penetrate the micro-fractures or pore spaces of shale as the bit penetrates the formation.
  • Much gilsonite is used directly in its crude form, as insulation pipelines, particularly hot pipes, as water proofing and underating for wood and metal, and as paving, roofing and other uses with crude asphalt.
  • 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. The addition of specially-treated Gilsonite to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shales, and seals off highly permeable sands while reducing torque and drag.
  • 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.
  • Gilsonite is generally soluble in aliphatic and aromatic solvents at ambient temperatures. Some agitation should be used. The rate of solution will depend on the type of solvent, the type and severity of mixing, and the grade of Gilsonite.
  • Gilsonite products are also approved by the U.S. Food & Drug Administration for use in resinous and polymeric coatings that come into direct contact with food.
  • Gilsonite is also used in protective coverings, anticorrosive paints, roofing compounds, dark rotogravure printing inks, carbon electrodes for the nuclear industry, varnishes, and as a reducing agent in slurry explosives
