In order to drill a successful oil well, most drilling operators will use a good drilling fluid or mud. Mud cools and lubricates the drilling tool, helps to attack the rock by injection under pressure, and cleans out the hole, carrying away the pieces of crushed rock [1]. These mud systems are usually WBM (Water-Based Mud), OBM (Oil-Based Mud) or SOBM (Synthetic Oil-Based Mud). One of the major problems with these systems, particularly when reused on different wells, is the build-up of very fine micron solids (less than 5 microns) known as Low Gravity Solids (LGS).
