UltraMARINE

Seawater-based fracturing fluid

UltraMARINE seawater-base fracturing fluid is engineered to provide optimized viscosity at bottomhole conditions to improve fluid performance during the fracturing operations in offshore operations. It provides effective temporary scale inhibition for application in reservoirs with scaling tendency waters and mitigates the risk of scale precipitating from the seawater by controlling the pH.

UltraMARINE fluid has a high tolerance-to-salt content and has been tested in waters with total dissolved solids in excess of 100,000 ppm. UltraMARINE fluid eliminates the dependency of freshwater-for-offshore fracturing and can be used with brackish water for onshore operation in areas where freshwater availability is limited.
