Expandable tubular element for use in a wellbore
First Claim
1. An expandable tubular element having a wall including at least a portion formed of a plurality of stacked wall layers, each wall layer having a bent configuration in a cross-sectional plane prior to radial expansion of the tubular element and being arranged to deform from the bent configuration to a more stretched configuration upon radial expansion of the tubular element, wherein the tubular element includes at least one cavity, each cavity being formed between a pair of adjacent wall layers prior to expansion of the tubular element, said cavity containing a body of fluid in the form of a bonding agent or a compound for forming a bonding agent, which bonding agent is suitable to bond said adjacent wall layers to each other or to bond the tubular element to a wall extending adjacent the tubular element.
