Abstract
A method and apparatus for use in setting sidetrack plugs in a well bore. The apparatus comprises an inflation packer assembly which may be attached to the lower end of the tubing string. The packer is inflated to seal against the well bore at the lower end of the sidetrack plug. The inflation packer is attached to a tubing string with a length of tail pipe. The tail pipe is releasably attached to the tubing string. After the inflation packer is sealed against the well bore, a cementitious fluid is circulated above the bladder to form the sidetrack plug. The tailpipe is then released and the tail pipe and the inflation packer remain in the hole and form a part of the sidetrack plug. An additional embodiment includes a whipstock connected to the inflation packer assembly.
