Bringing the well into operation with maximum productivity requires proper selection of chemicals for drilling muds.  The rate and workability of penetration, fail safety, drilling-in quality are influenced by drilling mud quality and composition. It is chemically treated to obtain necessary physical, chemical and technological properties.

Components are selected according to the objectives; the quality of bore production and safety level directly depend on the adequate choice of reagents as well as on their ratio.

The main functions of the drilling fluids include:

• Removing of drill cuttings from borehole

• Maintaining the suspension state of drill cuttings

• Borehole pressure adjustment

• Wall cake building

• Maintaining well shaft stability

• Corrosion prevention

• Transfer of hydraulic horsepower to the bit, lubrication and cooling
