n: an invert emulsion is a water-in-oil emulsion where fresh or salt water is the dispersed phase and diesel, crude or some other oil is the continuous phase and increase the viscosity and oil reduces the viscosity.

n: a drilling mud, e.g., oil-base mud and invert-emulsion mud, in which oil is the continuous phase. It is useful in drilling certain formations that may be difficult or costly to drill with water-base mud. Compare oil-emulsion mud.

n: 1.A mud in which the external phase is a product obtained from an oil, such as diesel oil or mineral oil. 2.More generally, a mud system that has any type of nonaqueous fluid as the external phase. This definition would include the newer variety of oil mu

n: a water-base mud in which water is the continuous phase and oil is the dispersed phase. The oil is spread out, or dispersed, in the water in small droplets, which are tightly emulsified so that they do not settle out. Because of its lubricating abilities, an oil-emulsion mud increases the drilling rate and ensures better hole conditions than other muds. Compare oil mud.

n: any conventional or special water-base mud to which oil has been added. The oil becomes the dispersed phase and may be emulsified into the mud either mechanically or chemically. Also called oil-emulsion mud.
