Drilling fluid - Wikipedia
In geotechnical engineering, drilling fluid, also called drilling mud, is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells.One of the functions of drilling mud is to carry cuttings out of the hole.

Research and Application of Micronized Barite Drilling ...
Mar 02, 2016· When drilling wells in high temperature and high pressure (HTHP) fields, the drilling fluid properties are of utmost importance. If the viscosity of high density drilling fluid is too low, it will lead to barite sag and poor cuttings carrying capacity. However, lost circulation will occur due to high surge pressure and Equivalent Circulating Density (ECD) caused by high viscosity.
