LINER ISOLATION AND WELL COMPLETION SYSTEM Abstract In a wellbore having a liner hung from a higher string of pipe, a permanent packer and a seal unit are utilized to isolate the annulus between the liner and the wellbore surface. The downhole completion assembly, which comprises an on-off tool, a latch and seal assembly and a tailpipe, can be lowered into the packer and seal unit by the production tubing, with the latch mechanism of the latch and seal assembly snapping into a threaded portion of the packer. The on-off tool can be disconnected and the production tubing withdrawn from the well. Alternatively, the latch mechanism can be disengaged and the entire downhole completion assembly can be withdrawn from the well in a single trip.
