How does PowerTools calculate the bottom hole pressure?
A. PowerTools records both the shut in tubing pressure and bottom hole pressure. PowerTools also determines whether the bottom hole pressure was calculated or measured. If the bottom hole pressure was measured, then the system uses the pressure as given. If the bottom hole pressure was calculated, then PowerTools will recalculate the bottom hole pressure based on input and default values. PowerTools uses an iterative procedure to calculate bottom hole pressure based on the Cullender-Smith technique. This technique consists of iterations based on a calculation of the average Z-factor for the gas conditions, well depth and temperature.
