Definitions for "Shut-in pressure"
The pressure at the wellhead when valves are closed.
The surface pressure in a shut-in well (static pressure) exerted at the top of a wellbore. The SIP may be zero, indicating that the pressure exerted by any formations open to the wellbore are effectively balanced by the weight or pressure of the hydrostatic column of fluid in the well.
Pressure as recorded at the wellhead when the valves are closed and the well is shut in.
