ABSTRACT:
Methods and apparatus are provided for retrieving an inflatable packer of a type which may be passed through a small diameter tubing, seal against a relatively large diameter casing by passing fluid to the packer through a remedial tubing, and then be retrieved to the surface through the small diameter tubing. If the downhole equipment assembly becomes hung up during retrieval, fluid may be passed through the remedial tubing to release an upper portion of the packer actuator assembly from a lower portion of the packer actuator assembly. The released upper portion and remedial tubing may then be retrieved to the surface, and a conventional fishing tool utilized to subsequently retrieve the lower portion and the packer.
