  • Patent number: 9394750
    Abstract: A collet coupling for electric submersible pump shafts is provided. An example coupling for joining two shafts includes a tubular coupling member, and collet for fixing the coupling to a shaft via expandable fingers with ribs for latching into a groove on each shaft. Shoulders in the groove transmit axial load forces between the two shafts through the ribs, fingers, and collet. An example method includes attaching one end of the coupling to a shaft of an ESP unit already installed in a well, adjusting an axial reach of a threaded collet for attachment to a second shaft of an upper ESP unit, and engaging ribs of the collet into a groove of the second shaft to couple the two shafts. A sliding retainer allows quick release. An axial deviation distance may be factory-stamped on the ESP units for quick length adjustment and installation of collet couplings in the field.

  • Patent number: 9243479
    Abstract: A lateral is gravel packed without a junction in place in a single trip into the wellbore. A disconnect is provided between the isolation packer in the lateral and a main bore packer. The inner string assembly in the gravel packing completion releases a disconnect with a shift tool and then releases the main bore packer so that the inner string assembly takes out the main bore packer and the upper portion of the disconnect when pulling out of the hole. A junction is then placed into the main and lateral legs with a packer having a seal bore into which the production string is sealingly stabbed to produce out of the main bore and/or the just completed lateral.

  • Patent number: 9057246
    Abstract: Present embodiments are directed to a tubular catcher system configured to detect a falling tubular through a drilling rig and grip the tubular before it drops into the wellbore. A sensor configured to detect the velocity or acceleration of the tubular activates an actuation mechanism when the velocity or acceleration exceeds a specific threshold, indicating a falling tubular. The actuation mechanism forces a gripping mechanism into contact with the tubular, catching the tubular and sending energy from the tubular to a hydropneumatic shock absorber coupled to the actuation mechanism and/or the gripping mechanism.

  • Publication number: 20150144354
    Abstract: The present disclosure is directed towards, in general, retrieval tools operable for conveyance within a wellbore extending below a wellsite surface, and methods of using such retrieval tools. One such retrieval tool comprises an annular member operable to receive a conveyance terminating at a downhole tool lodged within the wellbore. The annular member may subsequently receive and engage a portion of the downhole tool. The retrieval tool also comprises a flapper selectively operable to sever the conveyance if the downhole tool cannot be dislodged from the wellbore.

  • Publication number: 20150136417
    Abstract: A rigidizer and method for its use in supporting a tubular string during handling operations. The rigidizer includes upper and lower sleeves which pivotally open and close to clamp about the string. The upper and lower sleeves are rigidly connected by a number of structural telescopic legs that allow adjustment to different lengths for accommodating different strings. The rigidizer is installed on the string when the string is in a horizontal position and provides structural support to thin-walled components during upending and handling. Once the string is vertically oriented, the rigidizer is removed prior to being run into a marine riser or well.

  • Publication number: 20150107850
    Abstract: An automated, electric tong system and methods usable for making-up and breaking out threaded connections between tubular members, wherein the electric tong system comprises a power tong for applying torque and rotating the upper tubular member, a backup tong for gripping tubulars, and a lift assembly for vertically moving the electric tong system into proper position to grip the upper and lower tubulars. The power and backup tongs and lift assembly of the electric tong system are integrated into a single transportable unit and operated by three separate electrical motors, controlled by a single driver. The backup tong is located below the power tong and comprises a pneumatic cylinder, which operates a backup door, and a linear actuator driven by an electric motor for use in latching the backup tong door in a closed position and applying or releasing a clamping force to a tubular, during make-up or break-out operations.
