GILSONITE / NATURAL BITUMEN IN CEMENTING 

GILSONITE IS AN EFFECTIVE LOST CIRCULATION MATERIAL THAT ASSURES ZONAL ISOLATION AND REDUCES ENVIRONMENTAL RISK.

As the challenges presented by today’s wellbore configurations increase, a properly designed cementing process is critical to keeping the wellbore isolated, protected and environmentally sound. 

For more than 50 years, the industry has depended on Gilsonite as a lost circulation material and a critical component for primary cementing operations in some of the world’s toughest drilling environments.

Adding Gilsonite during cementing operations enhances the characteristics that are critical to effectively cementing the casing, isolating hydrocarbon formations and preventing annular gas flow.

With its unique physical and chemical properties, Gilsonite provides a range of important benefits in slurry and set cement that are unmatched by any other single additive.

Cement slurry benefits

Gilsonite eliminates the problems of free water
By controlling free water, Gilsonite helps stabilize slurry and eliminates the need for – and cost of – additional free-water-control agents. As a lost circulation material, it also improves zonal isolation by preventing water channeling on the upper side of the wellbore.
