Bottom-hole Pressure

bottom-hole pressure

[′bäd·əm ‚hōl ‚presh·ər] (petroleum engineering) Gas-drive pressure recorded at the bottom of an oil-well shaft; used to analyze oil-reservoir performance and evaluate the performance of downhole equipment. The pressure in a well measured at a point opposite the producing formation.

Bottom-hole Pressure

the pressure at the bottom of a working oil, water, or gas well. The pressure at the bottom of a standing or temporarily shut-in well is called the formation pressure. The bottom-hole pressure may be determined reliably by measuring with a depth manometer. Since producing beds (for example, oil beds) are never horizontal, hydro-dynamic analyses of bottom-hole and formation pressures are usually conducted as applied to some horizontal plane, taking into consideration the pressure of a column of bed fluid between the plane and the bottom of a given well. Consequently, a distinction is made between actual and reduced bottom-hole (formation) pressure.
