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.
Claims15
A composition comprising fibres suspended into a base fluid, said fibres having cores formed from a material that is electrically and/or magnetically susceptible, wherein each core is individually coated by a polymer capable of melting or setting when the fibres are subjected to an electric current or a magnetic field.
A method of consolidating a formation surrounding a wellbore, comprising:
- introducing a composition as claimed in any preceding claim into the wellbore;
- allowing the fibres to accumulate in a region to be consolidated;
- and
- applying an electric current or magnetic field to cause the fibres to bond together by melting or setting of the polymeric coating.
