Abstract

A well intervention tool for shifting a door structure within a well casing. The well intervention tool has independently shiftable keys which releasably engage with portions of the door structure. When the keys are engaged with the door structure, the well intervention tool can be used to move the door structure uphole and downhole. The well intervention tool can include a vibration motor to cause the keys to vibrate in order to displace debris within the door structure. The well intervention tool can include a rotational motor to cause the keys to rotate in order to displace debris within the door structure. The keys can have teeth which are shaped and spaced to shift debris while minimizing damage to the well casing.
