Glossary

"Draw-down" pressure drawdown (∆P) is defined as the difference between the reservoir pressure and the flowing bottom hole pressure. Drawdown enables fluids to flow from the reservoir into the wellbore. The magnitude of the drawdown is a major controlling factor in a well's production rate.

"Oil field" an accumulation, pool or group of pools of oil in the subsurface that produces oil to surface.
