Abstract
A multi-expansion packer is deployed in a borehole. The multi-expansion packer includes an outer part and an inner part disposed within the outer part. An outer part pump expands the outer part with a first fluid to engage the outer part with an inner surface of the borehole. A leakage sensor is configured to detect a leakage of the first fluid from the outer part which causes at least a portion of the outer part to disengage from the inner surface. An inner part pump expands the inner part with a second fluid. A controller responds to the detected leakage to control the inner part pump to pump the second fluid into the inner part until at least the disengaging portion of the outer part re-engages the inner surface of the borehole. A method comprises steps performed during operation of the system.
