Applications include chemical enhancement of oil recovery.
Specifications
Polymer microcapsules have a size of 2...12 microns. The capsules are filled with two reagents that react and heavily release carbon dioxide. The capsules enter a reservoir filled with gaseous hydrocarbons together with water for flooding, with the latter to be a solvent for carrier polymers. The polymer solution produced from the material of the microcapsules produces a foam filled with CO2 that consequently gives an avalanche effect and displaces gaseous hydrocarbons.
