Bottomhole Pressure Bomb
Definition - What does Bottomhole Pressure Bomb mean?
Bottomhole Pressure Bomb is a pressure-fight container which records the pressure of a well at an opposite point to the producing formation. It has a thick wall, mainly made of steel, which is used for holding samples of gas and oil under pressure. It is used for determining the rate of production of the well. It is advisable to use the Bottomhole Pressure Bomb as the basis for falloff analysis rather than surface pressure so as to avoid various well problems. When the reservoir is tight enough, engineers can use the surface pressure, as the injection pressure is high enough to offer usable pressure record.
Petropedia explains Bottomhole Pressure Bomb
Bottomhole Pressure Bomb is often used by the operating personnel or engineers as the basis for falloff analysis. When the surface pressure is used as the basis for falloff analysis is followed, it is observed that the usable pressure record becomes unusable for a limited period of time as the pressure at surface drops to zero. This is a problem that can be solved by running pressure bomb to record the bottomhole pressure as it is normally done in other pressure behavior tests. Only the experienced engineers can know whether to use surface pressure record for accurate analysis. But in case of any doubts, Bottomhole Pressure Bomb must be used.
