Application Note: Particle Size Analysis For Drilling In Petroleum Industry

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 . These mud systems are usually WBM (Water-Based Mud), OBM (Oil-Based Mud) or SOBM (Synthetic Oil-Based Mud).
