Bottom-Hole Pressure (PBH)
Hydrostatic pressure at the bottom of the well calculated from the true vertical depth and the fluid densities in the wellbore.

Depending upon the context, either a pressure exerted by a column of fluid contained in the well bore or the formation pressure at the depth of interest.

“Bottom hole pressure” means the gauge pressure in psi under conditions existing at or near the producing horizon.

Bottom Hole Pressure (BHP)
The sum of all the pressure acting on the bottom hole and would typically be the surface pressure plus the force exerted by the column of fluid in the wellbore.
