n: the liquid in which solids are suspended or droplets of another liquid are dispersed, sometimes called the external phase. In a water-in-oil emulsion, oil is the continuous phase. Compare internal phase.

n: (1) The fluid phase that completely surrounds the dispersed phase. (2) The fluid phase of a drilling fluid: either water, oil, or synthetic oil. The dispersed (noncontinuous) phase may be solids or liquid.

the external phase in an emulsion.

n: the settling or rising of the particles of the dispersed phase of an emulsion. Identifiable by a difference in colour shading of the layers formed. Creaming can be either upward or downward, depending on the relative densities of the continuous and dispersed phases.

n: that part of a drilling mud . clay, shale, barite, and other solids - that is dispersed throughout a liquid or gaseous medium. forming the mud.

n: The scattered phase (solid, liquid, or gas) of a dispersion. The particles are finely divided and completely surrounded by the continuous phase.



the internal phase in an emulsion – i.e., the droplets or bubbles.

n: a mixture in which one liquid, termed the dispersed phase, is uniformly distributed (usually as minute globules) in another liquid, called the continuous phase or dispersion medium. In an oil-in-water emulsion, the oil is the dispersed phase and the water the dispersion medium;in a waterin- oil emulsion, the reverse holds.

n: A substantially permanent heterogeneous mixture of two or more liquids that do not normally dissolve in each other but are held in a dispersed state, one within the other. This dispersion is accomplished by the combination of mechanical agitation and pres

a physical mixture of two or more immiscible phases.

adj: when the opposite occurs of what is intended in a drilling fluid. In an invert water-in-oil emulsion, the emulsion is said to be flipped when the continuous and dispersed phases reverse.

n: in an invert water-in-oil emulsion is said to be flipped when the continuous and dispersed phases reverse.

n: a two-phase system, similar to an emulsion, in which the dispersed phase is a gas or air.

n: the dispersed material which forms through the insolubility gas dispersing in the fluid or melt solids

a gas in liquid emulsion. Common as a low density cleanout fluid or a frac fluid with reduced water content.

n: also called water-in-oil emulsion mud,oil is continual external phase and water is dispersed phase.

n: a water-in-oil emulsion in which fresh or salt water is the dispersed phase and diesel. crude. or some other oil is the continuous phase. Water increases d1e viscosity and oil reduces the viscosity.

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: an oil mud in which fresh or salt water is the dispersed phase and diesel, crude, or some other oil is the continuous phase. See oil mud.
