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 WebAug 2, 2024 · Quote (Petroleum) That is the well head shut in pressure, 1200 psig. dear petroleum. I agree with your point of view but the subsuface engineer says because of probability change of reservoir conditions in future, the actual wellhead shut-in pressure is grather than 1200 psig and is almost 1500 psig (based on their calculations).
