Hydraulic Landing Collar Without Ball Catcher Sub OM-HLC-WBC

The Hydraulically activated Collar is used with hydraulic set Liner Hangers to build pressure in the work string for setting of the Hanger hydraulically. The Liner Landing Collar has a latch profile for locking of the Liner Wiper Plug. The latch profile provides anti-rotational lock to the Liner Wiper Plug which enables fast drill-out.
The ball seat in the Hydraulic Landing Collar is shear pinned to the latch bushing. When a ball lands on the seat, pressure rises to set the hanger hydraulically. Additional pressure is then applied to shear the ball seat to establish circulation through the Landing Collar. The ball seat has a slotted bottom which enables circulation through the shoe without any restriction after landing on the shoe. All seals are of standard HNBR material. A robust anti-rotation profile and latch assembly is designed to receive the liner wiper plug. When latched. These plugs provide a redundant seal to those of the float equipment. The body of the landing collar is manufactured of material matching the grade of the liner casing, which provides performance equal to or greater than that of the liner casing.
