ABSTRACT:
A pressure monitoring apparatus for use in a tubing string having a landing nipple located therein above a well zone which is to be monitored includes a plug body, a mandrel sleeve, a pressure communication mandrel and a pressure sensor. The plug body is landed in the landing nipple, and has an axial body bore therethrough. The mandrel sleeve has a lower portion constructed to be sealingly received within the body bore, and has an axial sleeve bore disposed therethrough. The pressure communication mandrel has a lower portion constructed to be sealingly received within the sleeve bore, and has a pressure communication passage disposed therethrough for communicating the pressure sensor with the well zone. The pressure monitoring apparatus can be adapted for use in methods of monitoring pressure fall-off in a subsurface formation after injection of fluid into the formation, and also can be adapted for use in methods of monitoring a bottom hole shut-in pressure buildup in a production well.
