Abstract:
A composition for wellbore consolidation comprises fibers having a core formed from a material that is electrically and/or magnetically susceptible, and a polymeric coating. When the composition is placed in a wellbore in a zone to be consolidated and an electric current or magnetic field is applied, the fibers bond together by melting or setting of the polymeric coating.
