Bottom-Hole Pressure

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 (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.
