Drilling fluid is a very important part of the drilling operation.
•Drilling fluid has many functions and is very complex
•The understanding of the uses of drilling fluid can make a drilling operation successful Ten functions of a drilling fluid:
1.Transport cuttings
2.Release cuttings at the surface
3.Control bottom hole pressure
4.Cool and lubricate the bit and drillstring
5.Provide borehole stability
6.Provide buoyancy for the drillstring
7.Suspend cuttings when circulation is interrupted
8.Facilitate the retrieval of information from the wellbore
9.Protect formation productivity
10.Transmit hydraulic energy to the tools and bit
