RP-Bentonite is used as a drilling mud in civil work
Depending on thixotropic properties, viscosity, gel strength and filtration control ability of RP-Bentonite, it can be used as drilling fluids for drilling in all civil works.
- The functions of drilling fluids in civil work include:
1- Removal of cuttings from the bore hole.
2- Support the excavation by exerting hydro-static pressure on walls to prevent
3- Reduction of fluid loss and acting as a sealant to the walls of excavation and not
flow into the soil.
4- Prevention of cuttings from settling down when circulation stops.
5- Lubrication and cooling of the drilling bit and string.
