BORE PLUG ANALYSIS SYSTEM

A method can include receiving pressure data with respect to time acquired via a pressure sensor disposed in an uphole region of a bore of a well, where a plug is disposed in the bore to define the uphole region to one side of the plug and a corresponding downhole region to the other side of the plu...

Zusammenfassung:	A method can include receiving pressure data with respect to time acquired via a pressure sensor disposed in an uphole region of a bore of a well, where a plug is disposed in the bore to define the uphole region to one side of the plug and a corresponding downhole region to the other side of the plug; using at least physical properties of liquid in the uphole region and thermal information, computing a temperature and gravitational head induced density variation of the liquid in the uphole region; and, based at least in part on at least a portion of the pressure data and the temperature and gravitational head induced density variation of the liquid, determining a state of the plug and the bore from a plurality of states.
