Expandable casing goes into the well in one diameter, then as an expansion mandrel is either drawn through or pushed through, it expands by as much as 300%. The technology was recently developed and tested in a slotted form. This technology and a new solid form are the subject of several...

Interesting results are emerging from the ongoing research of a novel advancement—expandable tubular technology. Studies on the effects of expansion on the mechanical properties of postexpansion casing, the resistance of expanded casing to sulfide stress cracking
and Hoop (tangential)...

Expandable solid tubulars represent one of the most promising and rapidly advancing technologies in today’s battle to remove the remaining barriers to deepwater and ultra-deepwater development. Several companies are hot on a trail once considered the exclusive preserve of science fiction writers...
