| Zusammenfassung: | The invention is directed to a method for enhanced hydrocarbon recovery and to the use of a specific liquid composition. The method of the invention comprises
- injecting into a hydrocarbon reservoir a liquid composition that comprises a polymer and particles of an inorganic material in a liquid, wherein the polymer is linked to the particles of the inorganic material by means of a functional group, wherein the polymer has a lower critical solution temperature in the liquid, and wherein the liquid composition exhibits thermo-induced gelling;
- gelling the liquid composition due to a change in concentration of one or more ionic species. |
