SHUT-IN TUBING PRESSURE SITP is the surface pressure exerted at the top of a wellbore when it is closed either at the Christmas tree or the blowout preventer. If your home's water supply comes from a well, you may notice issues with low water pressure. Pressure buildup analysis describes the build up in wellbore pressure with time after a well has been shut in. Want to thank TFD for its existence? Checked bladder tank and it has proper air pressure. Replaced a noisy 3/4 Flotec with same model # and voltage.

STHP can be calculated by knowing the reservoir pressure, reservoir depth, fuild compostion and length of the well tubing. A typical wellbore storage coefficient for a vertical well is C= 0.01 bbl/psi and it could be reduced to 0.001 bbl/psi with a downhole shut-in. Flooding can damage not only treasured family possessions, but it can destroy flooring, furniture, and can even lead to structural damage or cause difficult to remove mold, which can be dangerous to your family's health. One of the principal objectives of this analysis is to determine the static reservoir pressure without waiting weeks or months for the pressure in the entire reservoir to stabilize.
