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.
