Abstract:
1. A well isolation apparatus for use in a wellbore, comprising: an isolator conveyed into the wellbore by a conveyance device, the isolator including a swage, an expansion cone, and a sealing element in substantially serial alignment; an actuator configured to sequentially engage the swage, expansion cone, and the sealing element, wherein the actuator includes: a sub connected to the sealing element, a compression sleeve transferring an axial loading on the expansion cone to the sub, a first locking member connecting the compression sleeve to the expansion cone, a second locking member connecting the compression sleeve to the sub, a release sleeve having a first diameter configured to retain the first locking member in an engaged position with the expansion cone, the release sleeve further comprising a reduced diameter neck, and a translating rod configured to shift the release sleeve to slide the neck into engagement with the first locking member; and a setting tool configured to axially compress the isolator to a concentric alignment of the swage, the expansion cone, and the sealing element at a seal formed between the sealing element and an adjacent surface in the wellbore.
