the action of particles forming adhering clumps on pipe.

v: to amass or collect. When oil and gas migrate into porous formations, the quantity collected is called an accumulation.

an economic quantity of hydrocarbon trapped in a permeable rock strata.

n: 1. a vessel or tank that receives and temporarily stores a liquid used in a continuous process in a gas plant. See drip accumulator. 2. on a drilling rig, the storage device for nitrogen-pressurised hydraulic fluid, which is used in operating the blow out preventers. See blowout preventer control unit.

n: Used to store nitrogen that provide the hydraulic oil energy for BOP operation.

canisters of hydraulic fluid, pressurized with a nitrogen gas cap of sufficient pressure and volume to operate all the rams on a BOP in case of power failure to the BOP.

a vessel that receives and temporarily stores a liquid used in the feed stock or the processing of a feed stream in a gas plant or other processing facility.

n: a bottle-shaped steel cylinder located in a blowout preventer control unit to store nitrogen and hydraulic fluid under pressure (usually at 3,(XK)pounds per square inch). The fluid is used to actuate the blowout preventer stack.

the initial nitrogen charge on a BOP accumulator that is placed before the fluid is pumped in to charge the accumulator.

n: the ability of a measuring instrument to indicate values closely approximating the true value of the quantity measured.

the closeness of agreement between the measure value and the exact value.
