Abstract:
1. A method of forming a connection between two tubulars, comprising: substantially non-rotationally stabbing an end of a first tubular into an end of a second tubular to a position wherein a shoulder on the first tubular contacts a mating shoulder on the second tubular and at least one formation on an outer surface of the first tubular is adjacent at least one mating formation on an inside surface of the second tubular; and forming a connection between the first and second tubulars by employing an expansion tool to plastically deform at least a portion of either the first tubular, the second tubular, or both the first tubular and the second tubular in a manner wherein the formations are mated, thereby substantially preventing axial movement between the first tubular and the second tubular.
