  • Patent number: 9273532
    Abstract: A wellhead securement arrangement releasably clamps casing strings such that they cannot move in an upwards or downwards longitudinal direction. Prior to being clamped, the securement arrangement secures the casing strings in a first position whereby cement returns are able to flow around the hangers towards the surface. Once cemented, the casing strings are released and moved upwardly, where the securement arrangement clamps the hangers into position, thus creating an axial load on the casing strings while also preventing movement in the upward and downward longitudinal directions.

  • Patent number: 9243460
    Abstract: Clamping devices for hanging or pulling wellbore rod strings each feature housing with an axial bore in which a number of clamping pieces are placed to wedge in place between the housing and rod string to perform a self-tightening action against the rod string under the weight thereof due to cooperation of beveled surfaces at the bore wall and exterior of the clamping pieces. Threaded fasteners fed through the housing wall aid in placement of the slips against the rod string. For use in pulling operations, the housing is sized for receipt in the latching mechanism of a tubing elevator for support by the same, whereby the tubing elevator can be used to pull out a stuck rod string. Some embodiments feature a circumferential gap in the housing to enable the housing to be slipped laterally onto the rod string.

  • Publication number: 20150101827
    Abstract: A technique facilitates avoidance of premature actuation of a liner hanger in a wellbore. The technique utilizes a running string which may be coupled to a liner having a liner hanger. The running string extends into the liner in a manner which creates an inner pressure region within the running string, an intermediate pressure region between the running string and the liner, and an outer or annulus pressure region surrounding the liner. The inner pressure region is initially isolated from the intermediate pressure region by a closure mechanism during, for example, movement downhole. The closure mechanism selectively closes off a port used to actuate the liner hanger.

  • Patent number: 8757277
    Abstract: The present disclosure relates to the field of drilling equipment for the discovery and production of hydrocarbons from the earth. In particular, this disclosure relates to a torque reaction device for coupling a pipe running tool to a top drive assembly on a drilling rig. In one embodiment, a system for coupling a pipe segment to a pipe string includes a top drive assembly, a pipe running tool, and a torque reaction device. The top drive assembly includes an output shaft and a link extending from the top drive. The top drive is operative to rotate the output shaft with respect to the link. The pipe running tool is coupled to the output shaft and is engageable with a pipe segment to transmit torque from the output shaft to the pipe segment. The torque reaction device couples the pipe running tool to the link.

  • Patent number: 8757276
    Abstract: A technique enables the efficient connection of communication lines in a well application by substantially reducing online rig assembly time. The technique reduces online time of the rig by sealably fastening a first connector of a downhole connection assembly to a segment of a communication line during offline assembly time to substantially reduce the online time requirements. The first connector is later connected to a corresponding second connector while the rig is online to complete the downhole connection assembly that joins communication line segments.

  • Patent number: 8739888
    Abstract: A casing gripper is stabbed into a casing and energized by a top drive, gripping the casing. The casing gripper includes a load bearing mandrel that has external threads. The casing gripper also includes a nut threaded over the external threads, and a wrench having a portion of the upper end of the load bearing mandrel inserted into an opening of the wrench. The wrench is configured to prevent rotation of the nut but allow axial movement while the op drive rotates the mandrel. The casing gripper includes a grapple coupled to the nut and extending along a portion of the lower end of the load bearing mandrel. The grapple moves axially with the nut an is configured to radially expand and engage a casing member.

  • Patent number: 8726984
    Abstract: A rotary table device is provided with means arranged for suspension of a pipe string. The rotary table comprises a rotary ring arranged rotatably about the central axis of the rotary table. The rotary ring is formed by two or more ring sections, each connected to a system comprising a bearing housing section rotatable relative to a base section, a bearing housing groove being formed in a base contact surface on the bearing housing section and a corresponding base groove being formed in an opposing bearing housing surface in the base section. The grooves form a curve-shaped track for a roller body and the groove has a curvature center coinciding with the central axis of the rotary table. The rolling diameter of the roller body exceeds the collective depth of said grooves, and a channel connecting the end portions of the bearing housing groove is formed in the bearing housing section.
