High-tech natural solution for sealing, filtration control, and maximum resistance in oil & gas and high-performance asphalt mixtures.

Gilsonite / Natural Asphaltite is a solid natural bitumen formed over millions of years through the transformation of petroleum. Its unique chemical structure makes it a high-value additive for drilling, cementing, and refining operations: it softens under subsurface heat, resists water, and is highly compatible with hydrocarbons.

Cabo Rojo produces private-label Gilsonite for leading companies in the oilfield services industry, supplying various markets with consistent-quality, high-performance products.
