Summary:Methods and apparatus enable expanding tubing in a borehole of a hydrocarbon well. According to some embodiments, an expander device includes a collapsible swage formed of collets, at least one slip arrangement and a hydraulic jack to stroke the swage through tubing to be expanded. In operation, expanding tubing may include securing an expansion tool to the tubing, lowering the tool and tubing into a borehole, actuating a collapsible expander of the expansion tool to an extended configuration, and supplying fluid pressure to a jack coupled to the expander thereby moving the expander through the tubing which is held by at least one of first and second tubing holding devices disposed respectively ahead of the expander and behind the expander.
