Bottomhole Injection Pressure (BHIP)
Definition - What does Bottomhole Injection Pressure (BHIP) mean?
Bottomhole Injection Pressure is the downhole pressure at which treated water is injected back into the reservoir so as to increase the hydrocarbon production rate. The Bottomhole Injection Pressure can be calculated when hydrostatic pressure exerted by the fluid in the wellbore is added and the pressure is measured by the pump installed at the surface during an injection test.
Petropedia explains Bottomhole Injection Pressure (BHIP)
In static conditions, the Bottomhole Injection Pressure is equivalent to the hydrostatic pressure of the wellbore fluid (normally mud or brine or water). If the well is shut-in through the blowout preventers and an additional pressure is applied at the surface, the Bottomhole Injection Pressure is equal to the hydrostatic pressure of the wellbore fluid plus the pressure applied at the surface. In a dynamic condition, when the wellbore fluid is being circulated, the pressure is equal to the hydrostatic pressure of the wellbore fluid plus the pressure required to overcome the friction to move the wellbore fluid from the bottom of the well to the surface.
