Abstract:
A method for hanging a first tubular assembly in a second tubular positioned in a well, comprisingplacing the first tubular assembly within the second tubular in an overlapping relationship with the first tubular assembly extending into the well from the second tubular;holding the first tubular assembly in place;expanding at least a portion of the first tubular assembly overlapping with the second tubular, which portion is substantially circular in cross section without longitudinal slits therethrough, partially or fully circumferentially past the yield point including drawing a swedge through the portion and expanding the second tubular adjacent the portion of the first tubular assembly partially or fully circumferentially through expansion of the first tubular assembly, the expanding being sufficient that elastic recovery for the first tubular assembly is less than elastic recovery for the second tubular to retain the first tubular assembly in circumferential compression and the second tubular in circumferential tension;removing the swedge from the first tubular assembly.
