Study and Review of Synthetic base Drilling Mud

Synthetic-based muds (SBM s) were developed as environmentally friendly alternatives to conventional petroleum derived oil-based muds (OBM s). Although each synthetic fluid is chemically unique, the physicochemical properties of the SBM s exhibit some common trends. SBM s are safer to work with, more biodegradable and more dispersible in seawater than conventional OBM s. On the other hand, SBM s are more viscous at low temperatures, thin more with increasing temperature, have lower thermal stability and do not dehydrate shales as readily as conventional OBM s. By adjusting the emulsifier package in each mud, these properties may be brought more in line with those of conventional OBM s.
