Drilling with synthetic-based muds (SBM's) or pseudo-oil-based muds (OBM's)has become commonplace in both the Gulf of Mexico and North Sea areas. Synthetics also are in use or their implementation is planned in numerous other regions, such as the Far East, Australia, Mexico, Continental Europe, South America, and Russia.
ventional SBM is to control the tempera-ture and pressure dependency of SBM (synthetic-based muds) viscosity and gel strengths. A new SBM, exhibiting a constant rheological profile over a broad range of temperatures and pressures, has recently been developed specifi-cally for deepwater operations. Unlike conventional SBM, the fluid exhibits a
