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: liquid added to dilute or dtin a solution.

the fluid added to a concentrated mixture to reduce the concentration of an internal phase or reduce its viscosity.

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 suspension of extremely fine particles in a liquid (such as colloids in a colloidal solution).

n: Subdivision of aggregates. Dispersion increases the specific surface of the particle, which results in an increase in viscosity and gel strength.

a mixture of a internal phase of solids, droplets or bubbles that stay relatively suspended in a continuous fluid.

n: the fluid droplets or solids that are dispersed throughout another liquid in an emulsion. Compare continuous phase.

n: The discontinuous phase of an emulsion, the dispersed droplets of emulsified fluid.

An emulsion that has swapped the internal phase to the external phase.

n: a stable. translucent micellar emulsion of oil. one or more surface active agents. water. and sometimes an electrolyte. A microemulsion is classed as an emulsion because it is a mixture of immiscible substances (oil and water) and because it can have oil-in-water and waterin- oil phases. It can also have a phase in which neither oil nor water is dispersed. however, but are alternated in layers. A microemulsion has certain properties that are like a solution rather than an emulsion: it is optically clear rather than clouded. and it is stable, i.e.. the oil and water do not separate. Microemulsions are used for chemical flooding of reservoirs. See chemical flooding, emulsion. solution.

an emulsion with very tiny, highly dispersed bubbles. May be very stable and highly viscous when the internal phase is high (>75%).

n: a kinds of gas basis drilling fluid that the gas as external phase and the fluid as internal phase.

n: see emulsion, reverse emulsion.

a common oilfield emulsion where oil droplets (the internal phase) are suspended and surrounded by the water (the continuous or external phase).

the percent of the total volume that the internal phase comprises.
