ABSTRACT:
A hydraulically actuated running and setting tool includes a stationary setting tool mandrel that is connected to the packer by releaseable collets. Variable volume chambers are provided in the tool that are arranged so that no downward movement of the components relative to the space in the well bore below the packer is necessary. Setting is accomplished by hydraulic pressure and testing of the packer can occur prior to release of the setting tool from the packer. Release of the setting tool from the packer occurs by pulling upwardly on the setting tool with equalization of the pressure above and below the packer or applying additional hydraulic pressure as in setting until sufficient force is developed to part a shear member.
