Concentration Of Barite In Drilling Mud

  • Drilling fluid - Chapter 2 - SlideShare

    Feb 20, 2015· 1. CHAPTER-2 DRILLING FLUIDS Drilling fluid -mud - is usually a mixture of water, clay, weighing material and a few chemicals. Sometimes oil may be used instead of water, or oil added to the water to give the mud certain desirable properties. Drilling fluid is used to raise the cuttings made by the bit and lift them to the surface for disposal.
