Patent ID: 8651192

Claim:
A bottom hole assembly (BHA) adapted to be connected to coiled tubing and positioned within a casing having an internal diameter, the BHA comprising: a packer assembly comprising at least a first annular sealing element, a second annular sealing element, and a spring embedded within the second annular sealing element, wherein the second annular sealing element has a harder durometer measurement than the first annular sealing element; an anchor assembly, wherein the anchor assembly is adapted to be set within the casing by fluid pressure and mechanically unset from the casing by the application of an axial mechanical force to the BHA; and a valve assembly and a release assembly adapted to selectively retain the unset anchor assembly and release the anchor assembly upon an increase in fluid pressure to a predetermined amount, wherein the application of the axial mechanical force to the BHA opens a valve seal within the valve assembly.
