Abstract:
Systems and methods for performing positive and/or negative pressure testing in managed pressure operations in subterranean well bores are provided. In some embodiments, the methods comprise: performing a positive or negative pressure test in a well bore in a subterranean formation, wherein the well bore is maintained in a closed pressure loop, and at least one choke valve is provided in communication with the well bore, the choke valve being coupled to a controller, and during the test in the well bore, monitoring an actual bottomhole pressure in the well bore using data from at least one downhole sensor in the well bore, and if the actual bottomhole pressure in the well bore increases or decreases, manipulating the choke valve using the controller to increase or decrease the bottomhole pressure in the well bore.

Claim (Index 7):
The method of  claim 1  wherein the closed pressure loop is maintained by an isolation device disposed at a well bore, wherein the isolation device does not comprise a rotating control device.
