the percent by weight loss of exposing a sample of material to an excess of acid.

n: CaSO4, microsolubility. Used for depressant of inorganic salt. Usually used for gypse drill fluid.

gyp or anhydrite, CaSO4.

n: the character of dissoling or dispersing rapidly and playing as soon as the powery fluid additive

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: a free-gas phase overlying an oil zone and occurring within the same producing formation as the oil. See associated gas, reservoir.

n: the free gas phase that is sometimes found overlying an oil zone and occurs within the same formation as the oil.

a zone of free gas above an oil deposit. The gas cap occurs where the oil is oversaturated with gas (past the solubility limit). When a gas cap is not present at discovery, the oil is above the bubble point.

n: (HLB) an expression of the relative attraction of an emulsifier for water and oil, determined lalgely by the chemical composition and ionisation characteristics of a given emulsifier. The HLB of an emulsifier is not directly related to solubility, but it determines the type of emulsion that tends to be formed. It is an indication of the behavioural characteristics and not an indication of emulsifier efficiency.

n: a plan or procedure, with respect to depth, for the type and properties of drilling fluid to be used in drilling a well. Some factors that influence the mud program are the casing program and such formation characteristics as type, competence, solubility, temperature, and pressure.

n: a proposed or followed plan or procedure for the type and properties of drilling fluid used in drilling a well with respect to depth. Some factors that influence the mud program are the casing program and such formation characteristics as type, competence

the calculated solubility point of an ion in solution (scale/brine stability calculations).

n: the degree to which a substance will dissolve in a particular solvent.
