WebJun 3, 2015 · Pseudosteady-state flow. Pseudosteady-state flow behavior is observed when a well reaches stabilized production from a limited drainage volume. For constant-rate production under pseudosteady-state conditions, the difference between the flowing wellbore pressure and the average reservoir pressure in the drainage volume is constant, … WebJan 24, 2024 · Wellbore pressure increases linearly up to the point where the formation starts to take drilling fluid. The pressure at this point is the leak-off pressure and is used to estimate formation fracture pressure. Like shut-in drill pipe pressure, leak-off pressure is added to the pressure of the mud in the hole. Example

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 ”. Web5.C.2 General calculation method ... gas, accumulates at the top. This produces a hump in the pressure at shut-in that is sometimes above the reservoir pressure. ... the wellhead pressure stays at A+P and the bottomhole pressure increases to A+2P. This induces an abnormal rise in the bottomhole gauge pressure that can be above reservoir pressure.
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.
