Drilling fluid(mud) is an important component in the drilling process. The drilling fluids(mud) performance very important functions in oil gas drilling,and HDD(Horizontal directional drillling).

Drilling fluids(mud) Function

  • Remove cuttings from well
  • Suspend and release cuttings
  • Control formation pressures
  • Seal permeable formations
  • Maintain wellbore stability
  • Cool, lubricate and support the bit and drilling assembly
  • Transmit hydraulic energy to tools and bit
  • Ensure adequate formation evaluation
  • Control corrosion (in acceptable level)
  • Facilitate cementing and completion
  • Minimize impact on environment

Drilling Fluid(mud) Types

There are several types of drilling fluids used depending on the drilling conditions encountered:

* Water-based muds are used most frequently. The base may be either:

o fresh water, or

o salt water.

* Oil-based muds.

* Synthetic materials. The oil and gas extraction industry has developed many new oleaginous (oil-like) base materials from which to formulate high-performance drilling fluids.

A general class of these fluids is called synthetic materials, such as

o The vegetable esters,

o Poly alpha olefins,

o Internal olefins,

o Linear alpha olefins,

o Synthetic paraffins,

o Ethers, and

o Linear alkylbenzenes, among others.

* Air and foam fluids may be used in drilling wells.

o These fluids are less dense than drilling muds.
