  • Publication number: 20250101829
    Abstract: A collar system for wellbore cementation includes a latch-in float shoe or a collar provided to run at the bottom of a casing and an inner string running inside the casing to be cemented until a latch-in adaptor engages into a receptacle or a drill pipe latch-in receiver. The inner string includes a tool which allows its full rotation to ensure make-up of the casing running tool to the casing. Full rotation of the inner string allows for safe make-up of the casing running tool to the casing;. As the inner string is disconnected and pulled out of the collar, a barrier plug is tensionally set into the collar.

  • Patent number: 12123280
    Abstract: Embodiments presented provide for an apparatus that provides a dislodgable plug seat that is used to capture a cement wiper plug for wellbore cementing operations. The apparatus further includes a collar having a ball seat and a closing sleeve configured to be shifted from an open position to a closed position. In the open position, a fluid pathway between an interior volume and a wellbore annulus is unblocked, and in the closed position the fluid pathway is blocked. A split ring is shiftable with the closing sleeve between a retained configuration when the closing sleeve is in the open position and an expanded configuration when the closing sleeve is in the closed position. The split ring holds the dislodgable plug seat in place within the body in the retained configuration and releases the dislodgable plug seat in the expanded configuration.
