General Information:

Oil Drilling Starch is used for reducing fluid loss in a variety of water based drilling fluids and has beneficial secondary effects on mud rheology. In drilling wells, a liquid (mud) is pumped into the hole to clean and cool the drill bit and to flush to the surface the drill bit cuttings and suspending the drill cuttings while drilling is paused. The most important physical characteristics of the drilling fluid is the viscosity and the water holding/retaining characteristics.
