Composite tubulars that have not been polymerized and are thus flexible enough to be coiled are delivered into a wellbore and expanded. The expansion occurs from an external catalist such as heat or releases the internal catalyst and allows the expanded tubular to become rigid. Optionally, healing agents can be imbedded in the tubular wall to be released to seal subsequently forming cracks.
