  • MODIFYING EXPANSION FORCES BY ADDING COMPRESSION
    Publication number: 20110253394
    Abstract: A method for expanding a tubular in a borehole, the tubular having upper and lower ends, the system comprises a) applying a compressive load to the upper end of the tubular and b) expanding the tubular by moving an expansion device relative to the tubular while maintaining the compressive load. Step a) may include resting a weight on the upper end of the tubular or applying hydraulic pressure to the upper end of the tubular. The lower end of the tubular may engage the formation before step b) or as a result of step b).

  • Forge welding tubulars
    Patent number: 7774917
    Abstract: Tubular ends are heated to a predetermined temperature above 1200 degrees Celsius and surrounded by a shield gas when the tubular ends are pressed together to form forge welded tubular ends. The forge welded tubular ends are then cooled down rapidly from said temperature above 1200 to at most 600 degrees Celsius within 3 minutes after the forge welding operation.

  • Joining expandable tubulars
    Patent number: 7181821
    Abstract: A method of joining expandable tubulars includes joining the tubulars by forge welding and flushing a reducing flushing gas around the heated tubular ends during at least part of the forge welding operation such that oxides are removed from the forge welded tubular ends and the amount of irregularities between the forge welded tubular ends is limited.
