Abstract
A system includes an integrated liner hanger assembly that includes a liner hanger, a packer, and a cement retainer sub. The cement retainer sub includes a plurality of fluid passageways connecting a central bore of the liner hanger assembly to an annular volume downhole of the packer and uphole of the liner hanger. A running tool is configured to axially translate a sliding sleeve of the cement sub from a closed position to an open position in which flow if permitted through the passageways, and from the open position to a closed-and-locked position. In some embodiments, the system is configured such that running the assembly into the wellbore, actuating the liner hanger, actuating the packer assembly, translating the sliding sleeve from the closed and open position and from the open position to the closed-and-locked position, are completed in a single trip.
