Drilling mud natural pitch is similar to hard petroleum asphalt and is often called natural asphalt, it is soluble in aromatic solvents, as well as petroleum asphalt , due to its unique compatibility, Gilsonite is frequently used to harden softer petroleum products.
1. Gilsonite is used in drilling mud fluids and oil well cementing.
2. The addition of special-treated Gilsonite to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shale’s.
3. The addition of Gilsonite to oil well cements reduces slurry weight without loss of compressive strength and acts as an effective bridging and plugging agent to seal fractures in week formations while cementing.
