n: a bucket of water into which air from the drill stem is blown through a hose during the first low period of a drill stem test. In drill stem testing, the flow into the bubble bucket is an easy way to judge flow and shut-in periods.

n: the average pressure within the reservoir at any given time. Determination of this value is best made by bottomhole pressure measurements with adequate shut-in time. If a shut-in period long enough for the reservoir pressure to stabilize is impractical, then various techniques of analysis by pressure buildup or drawdown tests are available to determine static reservoir pressure.

the pore pressure in the reservoir, usually at current value unless otherwise specified.

n: an interval during which a well is shut in to allow pressure buildup while pressure behavior is being measured during a formation test.
