Abstract
An isolation plug includes a ratchet wedge having a set of threads formed along an interior surface of the ratchet wedge, where the set of threads are configured to permit movement in a first direction and restrict movement in a second direction. The isolation plug also includes a ratchet shoe configured to shift in the first direction to ratchet into the ratchet wedge to engage the ratchet wedge, where the ratchet shoe has a corresponding set of threads that are configured to engage the set of threads of the ratchet wedge to permit the ratchet shoe to shift in the first direction, and restrict movement in the second direction. The isolation plug further includes a packing element positioned in between the ratchet shoe and the ratchet wedge, the packing element configured to expand radially as the ratchet shoe is shifted in the first direction.
