Abstract:
A formation tester tool includes an extendable probe having an extendable member configured to extend from a retracted position to an extended position such that an end of the extendable probe is in fluid communication with a wall of a borehole during an operation to capture a fluid from a formation. The formation tester tool also includes a sealing pad positioned circumferentially around the extendable probe, wherein a face of the sealing pad is configured to sealingly engage the wall of the borehole while the extendable member is in the extended position. The formation tester tool also includes a shield to cover the sealing pad in a covered position between the sealing pad and the wall of the borehole.
