WebSep 20, 2024 · Bottom Hole Pressure (BHP) = Surface Pressure (SP) + Hydrostatic Pressure (HP) The image below demonstrates the relationship of bottom hole pressure. Note: BHP created by hydrostatic column of drilling fluid is the primary well control in drilling. If BHP is more than FP (formation pressure), this situation is called “ Overbalance ”. WebThe shut-in surface pressure at the start of each period is obtained from the pressure decline curve. A series of wellhead flowing pressures is assumed, and the flow rate for that well is calculated for each wellhead pressure. This is repeated for each production period. Table 13-1 gives an example of the output from this series of calculation.
