CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2022/234132
Kind Code:
A3
Abstract:
A connector (200) for securing an inner tubular (105) to an outer tubular (107) includes an inner gripper (220), and outer gripper (210); and a wedge (230). The connector (200) is configured to be located in an annulus between the inner tubular (105) and the outer tubular (107), and to be moveable from a collapsed configuration where the inner tubular (220) can move relative to the outer tubular (210), to an expanded configuration; the inner tubular (105) is secured by the connector (200) to the outer tubular (107). The wedge (230) is configured to be driven between and moveable relative to outer and inner surfaces of the outer gripper (210) such that, in use, movement of the wedge (230) causes movement of an inner surface of the inner gripper (220) radially inwards towards the inner tubular (105) and/or movement of the outer surface of the outer gripper (210) radially outwards towards the outer tubular (107), thereby moving the connector (200) from the collapsed configuration towards the expanded configuration. In the expanded configuration the inner surface of the inner gripper (220) is engaged with the inner tubular (105) and the outer surface of the outer gripper (210) is engaged with the outer tubular (107).
