bottom hole shut-in pressure.

The pressure at the bottom of the well. In a producing well the BHP may be the bottom hole flowing pressure or the bottom hole shut-in pressure. In a drilling or workover environment, the BHP is exerted by the column of fluid in the hole.

n: a test that measures the reservoir pressure of the well, obtained at a specific depth or at the midpoint of the producing zone. A flowing bottomhole pressure test measures pressure while the well continues to flow;a shut-in bottomhole pressure test measures pressure after the well has been shut in for a specified period of time. See bottomhole pressure. bottomhole pressure gauge.

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.

v:.1. to shut in a well temporarily that is capable of producing oil or gas. 2. to close the blowout preventers on a well to control a kick. The blowout preventers close off the annulus so that pressure from below cannot flow to the surface.

v: (1) Close the production well temporarily. (2) Close the BOP to prevent blowout.

n: the equipment with thermosensor to shut the multi-effect preventer ,when the tempreture reach to 100 Celsius degrees or predicated value ,the hydraulic-pressure force of energy accumulator shut the preventer

n: a high rate of flow from a newly drilled well.

the early, higher rate production that comes from the larger pores, fractures and vugs that empty quickly. Delivers a small, high rate flow every time the well is shut-in (recharges) and is brought back on line.

n: the force exerted by fluids in a formation, recorded in the hole at the level of the formation with the well shut in. Also called reservoir pressure or shut-in bottomhole pressure.

n: the pressure exerted by the formation fluids at a particular point in the formation,sometimes called reservoir pressure or pore pressure.

the pressure of the fluid in the formation. The initial reservoir pressure is the pressure at discovery.
