Drilling Fluid Roles

✓ The drilling fluid plays several functions in

the drilling process.

✓ The most important are:

➢clean the rock fragments from beneath the bit

and carry them to surface

➢exert sufficient hydrostatic pressure against the

formation to prevent formation fluids from

flowing into the well

➢maintain stability of the borehole walls

➢Cool and lubricate the drillstring and bit.
