SELF-REPAIRING ISOLATION SYSTEMS

摘要

The present invention discloses a composition for completing a well comprising a pumpable fluid made of a settable material and a reactive material able to swell in contact with liquid and/or gaseous hydrocarbon and/or water and/or carbon dioxide, said reactive material added in a quantity such that after the composition sets, a flow path of liquid and/or gaseous hydrocarbon and/or water and/or carbon dioxide created within the set composition will be stopped by swelling of the reactive material.
