Abstract

See full text

An actuatable wellbore isolation assembly including a housing defining an axial flowbore and including a mandrel portion, a first end portion, and a second end portion; a radially expandable isolating member positioned circumferentially about the housing; a sliding sleeve circumferentially positioned about the mandrel, the sliding sleeve being movable from a first position, in which the sliding sleeve retains the isolating member in a narrower non-expanded conformation, to a second position, in which the sliding sleeve does not retain the isolating member in the narrower non-expanded conformation; and an actuator assemblage configured to allow movement of the sliding sleeve from the first to the second position. In an exemplary embodiment, the actuator assemblage includes a biasing chamber having a biasing member disposed therein, wherein the biasing member is configured to apply a force to the sliding sleeve to move the sliding sleeve from the first to the second position.
