ABSTRACT:
A method and apparatus for sealing a well annulus, the apparatus comprising a resilient sealing element molded in a upwardly oriented frustro-conical form affixed to a packer body. A running tool is mated with the packer body, the running tool having an internal bore adapted to collapse the sealing element to the diameter of the internal bore. The packer body is mated with a tubing screen by right hand threads and the running tool, packer body and tubing screen lowered into a well casing at the end of a pipe string. The well seal is activated when the pipe string is rotated in a clock-wise direction, disengaging and withdrawing the running tool and releasing the skirt which expands to seal with the internal walls of the casing.
