Mud Rotary Drilling: In this method, fluid is pumped down a hollow drill pipe and forced out of drill bit jets. It is primarily used on loose grounds with minimal or no rock beneath. Chemicals like Bentonite clay (Gel), Barium sulfate (Barite), Calcium carbonate (chalk), and Hematite play crucial roles in this process. Cost: Roughly KES 14,050 ...

Guar Gum is often used as an alternative to Bentonite for high-viscosity sweeps when drilling top-hole offshore because it is quick and easy to mix in seawater. Guar Gum is useful for keeping up with drilling progress and for conserving stocks of fresh water and/or Bentonite. The standard formulation for mixing Guar Gum is as follows:
