Abstract: A method of conducting a pressure integrity test for an underground formation includes: whilst fluid is supplied to and/or released and returned from the underground formation under pressure, using an automated monitoring and supervisory system to: monitor the pressure of the fluid being supplied to and/or returned from the underground formation in real-time, monitor a volume of the fluid that is supplied to and/or returned from the underground formation in real-time, determine one or more relationship(s) for the monitored pressure and the monitored volume as the pressure and the volume vary relative to each other and/or with time during the real-time monitoring thereof, and analyze the monitored pressure and volume data using the one or more relationship(s) either in real-time or after completion of the pressure integrity test in order to provide information and/or warnings concerning at least one parameter relating to the underground formation.

Abstract: A method of conducting a pressure integrity test for an underground formation (42). The method including: whilst fluid is supplied to and/or released and returned from the underground formation under pressure, using an automated monitoring and supervisory system (26) to: monitor the pressure of the fluid being supplied to and/or returned from the underground formation in real-time, monitor the volume of fluid that is supplied to and/or returned from the underground formation in real-time, determine one or more relationship(s) for the monitored pressure and the monitored volume as they vary relative to each other and/or with time during the real-time monitoring thereof, and analyse the monitored pressure and volume data using the relationship(s) either in real-time or after completion of the pressure integrity test in order to provide information and/or warnings concerning one or more of: parameters relating to the underground formation.
