Why do we use barite/ baryte in oil drilling area as drilling mud?
Reasons for barite’s use over other materials:
- Neutrality - chemically, physically and magnetically neutral
- environmentally acceptable from the standpoint of its disposal as part of the drilling fluid.
- Far less abrasive than other materials and does little damage to drilling equipment.
- Low cost
Applications:
- To clean cuttings from the well bottom.
- Flush those cuttings to the surface.
- Cool and lubricate the drill bit.
- Deposit a “ filter cake’ layer on the well bore wall to prevent loss
of the circulating fluid.
- Prevent formation fluids entering the borehole and mixing with circulating fluids.
- Support the walls of the well bore without damaging the formation.
- Control pressures under the surface.
