n: a drilling technique that uses air or gas to which a foaming agent has been added.

n: A variation of air drilling in which a small amount of water trickles into the wellbore from exposed formations and is carried out of the wellbore by the compressed air used for air drilling. The onset of mist drilling often signals the impending end of p

v: to prepare drilling fluids from a mixture of water or other liquids and any one or more of the various dry mud-making materials (such as clay, weighting materials. and chemicals).

n: the process that mixes the water or other fluid with a kind or more kinds of material .

n: preparation of drilling fluids from a mixture of water and other fluids and one or more of the various dry mud-making materials such as clay and chemicals.

n: any tank or vessel used to mix components of a substance (as in the mixing of additives with drilling mud).

a preporation tank for gel, mud, treating chemicals, etc.

abbr: million standard cubic feet. The standard referred to is usually 60�F and 1 atmosphere (14.7 pounds per square inch) of pressure, but it varies from state to state.

millions of standard cubic feet.

n: a measure of the ease with which a fluid moves through a reservoir. Mobility is measured by dividing a formations permeability to a fluid by the fluids viscosity.

n: a polymer-water solution used in micellar-polymer flooding as a zone of viscosity transition between the initial injection of surfactant-water solution and the final injection of drive water. The lead edge of the polymer solution has a mobility equal to or less than that of the surfactant solution. and the trailing edge has a mobility close to that of water. This buffer zone prevents the drive water from fingering past the surfactant solution and thus reducing sweep efficiency. See micellar-polymer flooding.

n: a description or analogy used to help visualise something that cannot be observed directly, such as the structures, porosities, and permeabilities of a geological formation.

a trademarked name for a very common packer.
