    摘要： An auto-fill type float collar assembly is provided. The float collar assembly of the present invention has at least one curved flapper-style valve, preferably constructed of composite, non-metallic material. Each flapper of the present invention has a substantially 90° range of motion, and is closed via a torsion spring. Each flapper is held in the open (or “auto-fill”), position via an external shifting mechanism passing around, rather than through, the central flow bore of the assembly. A floatable actuation ball can be run with the tool, or pumped downhole, in order to selectively actuate the assembly and close the flappers when desired.

    摘要： A connection assembly for automated lifting and positioning of a chiksan or other fluid conduit in proximity to a fluid inlet of a device such as, for example, a cement head. Once a chiksan or other flow line is positioned in a desired location, a secure connection is made between the outlet of the chiksan or other fluid conduit and the fluid inlet of a cement head including, without limitation, when the cement head is positioned at an elevated location above a rig floor.

    摘要： An anchor assembly for anchoring casing or other pipe against axial upward movement while permitting rotation of the casing or other pipe. An inner mandrel member has a central bore and a flange member extending around the outer circumference of the mandrel. A friction reducing ring member is located on an upper surface of the flange member, while layered friction reducing sleeve members are positioned around the outer surface of the mandrel member. An anchor sleeve member is concentrically and rotatably positioned around the outer surface of the outermost friction reducing sleeve member. Connection flanges, each having at least one bore for attachment to a shackle or other connecting device, extend laterally from the outer periphery of the anchor sleeve member and allow for anchoring of the assembly (and any attached casing or other pipe) to a rig or other structural support member.

    摘要： A centralizer assembly having a tubular body member with upper and lower channels extending around the external surface of said central tubular body member. A bow spring assembly having bow spring members is installed around the outer surface of the tubular body member and can rotate about the outer surface of the central tubular body member. Bow spring heel supports prevent the bow spring members from contacting the outer surface of the central tubular member when compressed. Non-abrasive materials prevent damage to wellhead or other polished bore receptacles. A robust bolster frame protects the centralizer assembly during shipping, storage or other periods of non-use.
