SIDPP meaning in oil and gas

Shut-In Drill Pipe Pressure

1. Note: this is a simplified explanation - SIDPP is a drilling and/or prodcution operations measurement derived by closing the RAMS on the drillpipe or drilling assembly thus closing-in the well annulus around the pipe; any pressure buildup or drop is then read on a gauge located at the surface on the stand-pipe; this value can then be used to calculate the state of over or under-balance between the drill fluid hydrosatic pressure and the formation pressure and thus estimate a formation pressure; derive necessary pressure states needed to regain well control (value may also be used in well control operations) <p> a. present technology incorporated into LWD (Logging While Drilling Tools) allow this value to be captured downhole and by comparison to the conventional value can be used for a variety of discrete purposes such as identifying gasified annulus, etc.
