<p>Treating porous and permeable formations or subterranean cavities comprises: preparing a composition comprising a particle system of polycation/polyanion complexes of micrometric or nanometric size obtained by mixing of at least two water in oil emulsions, where a first emulsion contains an anionic polymer in water and a second emulsion contains a cationic polymer in water, and the granulometry of the complexes is controlled by granulometry of the first and second emulsions; and injecting the composition in the porous and permeable formation in which water, oil and/or gas flows.</p> |
