Shut-In Drill Pipe Pressure (SIDPP)
Definition - What does Shut-In Drill Pipe Pressure (SIDPP) mean?
Shut-in drill pipe pressure is the pressure of a drilling fluid inside the drill stem. It is majorly used for measuring the difference between the formation pressure and the hydrostatic pressure when the well is shut after a mud pump is turned off. It calculates the required mud weight increase to kill the well.
Petropedia explains Shut-In Drill Pipe Pressure (SIDPP)
Pressure is a very important concept in the oil and gas industry. Shut-in drill pipe pressure is one of the ways pressure can be measured in a well. Pressure is defined as the force exerted per unit area. Pressure is widely used in the petroleum industry in units of pounds-force per square inch. Shut-in drill pipe pressure is measure during a well shut-in. The pressure created by the wellbore stabilize and the formation pressure should be equal to the pressure at the bottom of the hole. The pressure measure is the easiest to calculate and gives direct of formation pressure during a kick.
