Patent ID: 8276677

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 perforating assembly, the perforating assembly including a fluid path in communication with the coiled tubing; a packer assembly, the packer assembly comprising: an upper packer mandrel connected to the perforating assembly, the upper packer mandrel having a fluid path in communication with the fluid path of the perforating assembly; a packer filter housing slidably connected to the upper packer mandrel, the packer filter housing including flow ports in communication with an annulus between the coiled tubing and an internal surface of the casing; a lower packer mandrel connected to the upper packer mandrel, the lower packer mandrel having a fluid path in communication with the fluid path of the upper packer mandrel; a lower packer crossover member; a first annular sealing element, the first annular sealing element being connected to the packer filter housing and to the lower packer crossover member, wherein a downward movement of the packer filter housing with respect to the lower packer crossover member engages the first annular sealing element with the internal surface of the casing to create an initial seal; a second annular sealing element connected to the first annular sealing element and the lower packer crossover member; a spring embedded within the second annular sealing element, wherein annular pressure may communicate through the packer filter housing flow ports to engage the first and second sealing elements with the internal surface of the casing to pressure-energize the initial seal; an anchor assembly that may be repeatedly moved between a set position and an unset position within the casing, the anchor assembly comprising: an anchor housing, the anchor housing being connected to the lower packer crossover member; an anchor mandrel being axially slidable within the anchor housing; a plurality of anchor slips extendable from the anchor housing; a release assembly, the release assembly adapted to selectively retain the anchor in the unset position, wherein an increase in pressure within the BHA to a predetermined amount releases the anchor to move to the set position; a valve assembly connected to the release assembly.
