Abstract
In one embodiment, a method of completing a wellbore (10) includes positioning an expandable tubular having a support layer (121) disposed on an exterior of the expandable tubular inside a casing (15); mechanically expanding the tubular and the support layer, wherein a distance between an outer diameter of the support layer and the inner diameter of the casing is sufficient to prevent burst of the tubular; and hydraulically expanding the support layer into contact with the casing.
Claims18
A method of completing a wellbore, comprising:
- positioning an expandable tubular having a support layer disposed on an exterior of the expandable tubular inside a casing;
- mechanically expanding the tubular and the support layer using an expansion tool in contact with the tubular, wherein after mechanical expansion, a distance between an outer diameter of the support layer and an inner diameter of the casing is 0.08 inches or less to prevent bursting of the tubular;
- and
- contacting pressurized fluid against the tubular to further expand the tubular directly by the pressurized fluid, thereby hydraulically expanding the support layer into contact with the casing.
