Abstract: A method and apparatus for providing an expandable threaded connection between segments of expandable tubulars. Threaded connections are machined into pre-expanded ends of tubulars. Once the threaded connections are machined into the pre-expanded ends, two joints of tubulars are connected using the threads, thus creating a pre-expanded threaded connection. After a tubular string is made up and lowered into a wellbore, the entire length of the string is expanded using known methods for expanding tubulars. During the downhole expansion operation, the pre-expanded threaded connections experience minimal expansion. The minimal downhole expansion of the pre-expanded threaded connections allows the threaded connections to maintain their sealing ability and coupling strength.

Abstract: A fluid coupling includes various features. One feature is a disconnect tool that may expand a lock ring from engagement with a lock shoulder to permit the male half and female half to be separated. Another feature is to utilize geometry and structure whereby a leak would occur to indicate the condition of wear within the coupling while the coupling halves remain mechanically coupled. A further feature is to provide connection verification structure to assure that a complete connection of the male and female halves has been made. A still further feature is to provide an anti-rotational sleeve which would selectively prevent and permit relative rotation between the male half and the female half.

Abstract: A coupling assembly for connecting two members is provided that includes a first “male” member and a second “female” member. The first member includes a release sleeve moveably mounted thereon having a rigid release portion and a flexible sealing portion. The second member is integrated into an apparatus, such as a pump, and includes a duct therethrough for receiving the first member. Upon connection of the first and second members, the flexible sealing portion sealingly engages a recessed seat portion of the second member to substantially inhibit the ingression of contaminates into the duct when the first and second members are connected. The foregoing coupling assembly is advantageous because it allows the second member to be formed directly into an apparatus. In other embodiments, the coupling assembly provides an improved release sleeve that releases the male member from both a conventional female member and an integral female member.
