ABSTRACT:
A permanently installed, remotely monitored and controlled transient pressure test system is provided. This system utilizes shut-in/choke valves, pressure sensors and flow meters which are permanently associated with the completion string to perform transient pressure tests in single and multiple zone production and injection wells. The present invention permits full bore testing which thereby eliminates undesirable wellbore storage effects. The present invention further allows for pressure testing limited only to a selected zone (or zones) in a well without expensive well intervention and without halting production from, or injection into, other zones in the well. The permanently located pressure test system of this invention also allows for real-time, downhole nodal sensitivity and control. This pressure test system may be permanently deployed either in production wells or injection wells.
