The ACCOLADE(R) synthetic-based drilling fluid system was created to exceed EPA environmental criteria and is an entirely new, unique formulation. Results from system use show that ACCOLADE(R) meets or exceeds all applicable regulations governing discharge of cuttings generated with synthetic-based fluids (SBF) offshore Gulf of Mexico (GOM). Downhole mud losses normally associated with tripping, running casing, cementing and breaking circulation are reduced when compared to wells using traditional SBFs. The unique formulation of the ACCOLADE system results in less material required at the rig for fluid maintenance. This cutback translates into potentially fewer crane lifts, reduced transportation expense and less exposure of workers to potentially hazardous operations. Results show that the ACCOLADE synthetic-based drilling fluid meets or exceeds applicable environmental requirements and traditional performance standards because it contains no commercial clay or lignite additives. Rheological and fluid loss properties are controlled through the emulsion characteristics of the fluid. The base oil is an ester-internal olefin (IO) blend. The vegetable ester component of the base fluid makes the ACCOLADE system more biodegradable than conventional SBFs. The ACCOLADE system is characterized by desirable rheological properties over a range of temperatures from 40°F to 350°F, properties that provide unprecedented control over viscosity and equivalent circulating density (ECD). The fluid's gel strengths develop quickly but are fragile.
