  • Publication number: 20170096882
    Abstract: A liner hanger is initially set to the surrounding tubular. A standard bottom up cement job through a shoe at the liner bottom can be performed. If that job does not test satisfactory then the running tool can be unlatched at the packoff and raised beyond the liner hanger extension tubular so that a tack and squeeze job can be accomplished pumping the cement top down through the gaps in the liner anchor. The running tool can be re-latched to the liner hanger extension tube that is still unexpanded. Once re-locked into a groove in the extension the running tool for the liner hanger can be operated to set the seal and release the running tool from the groove in the extension to pull out of the hole. The liner hanger anchor and seal can be expanded into the set position by the running tool.
