Exceptional performance under high pressures and temperatures 

Volos™ non-aqueous drilling fluid is engineered to provide consistent rheological profiles and efficient drilling performance in HPHT applications up to 450°F. 

The Volos™ system maintains stable rheologies even during prolonged static conditions at extreme-temperatures. Combined with thin filter cake deposits, this delivers efficient logging, casing, and cementing operations – while the expertly engineered formula minimizes issues such as excessive equivalent circulating densities (ECD), lost circulation, stuck pipe and other issues while working to protect downhole tools.
