n: a procedure whereby a product may be subjected to intensified but controlled conditions of heat, pressure, radiation, or other variables to produce, in a short time, the effects of long- time storage or use under normal conditions.

n: The certain temperature in which mud and slurry lay in order to check out the variable relations between time and performance of mud and slurry.

n: The adjustable variables in optimization of drilling recommendation.

a surfactant whose charge is dependent on another variable, normally pH.

adj: of or pertaining to an instrument that measures a continuous variable that is proportional to another variable over a given range. For example, temperature can be represented or measured as voltage, its analog.

n: the representation of the magnitude of a variable in the form of a measurable physical quantity that varies smoothly rather than in discrete steps.

n: the depositional environments associated with a shallow lagoon shoreward from a coastal barrier island. These environments are highly variable and may include tidal channels, salt marshes, shell reefs, and mangrove swamps, among others.

n: The compounding transmiting and variable speed driving rig whose power package uses multi-line roller chain.

v: to take rams out of a blowout preventer and replace them with rams of a different size or type. When the size of a drill pipe is changed, the size of the pipe rams must be changed to ensure that they seal around the pipe when closed (unless variable-bore pipe rams are in use).

v: Bring out the pipe ram of BOP and install with other size or type of brake.

n: One of optimization method of drilling. Find the optimal drilling arrangement by changing bit load and keep rotate speed.
