What chemicals are used in drilling mud?

Drilling mud uses weighting agents like barite, viscosifiers like bentonite and polymers (PAC, CMC), fluid loss additives, shale stabilizers, lubricants, and lost circulation materials (LCM) to maintain wellbore stability and optimize drilling performance.

What is the role of barite in drilling fluid?

Barite (barium sulfate) is the primary weighting agent used to increase drilling fluid density, which helps control formation pressure and prevent well kicks or blowouts during drilling operations.
