Abstract:
There is provided a method for effecting at least partial interference of a fluid passage extending between a casing, disposed within a wellbore that is penetrating a subterranean formation, and the subterranean formation. The method includes detecting the fluid passage, and effecting an operative displacement of a casing section of the casing such that at least partial interference of the fluid passage is effected.
