bottom hole 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.

closed in bottom hole pressure.

a method of killing a well where the choke is adjusted to maintain a constant casing pressure as the a water kick rises in the annulus. The method should not be used with a gas kick (will not keep a constant BHP).

flowing bottom hole pressure.

n: pressure registered at the wellhead of a flowing well.

the pressure at some datum (usually surface, FSP, or bottom hole, FBHP, measured while the well is flowing.

static bottom hole pressure. May also be called shut-in bottom hole pressure.

n: (SIBHP) the pressure at the bottom of a well when the surface valves on the well are completely closed. It is caused by formation fluids at the bottom of the well.

abbr: shut-in bottomhole pressure;used in drilling reports.
