<p>The invention relates to a process for treating oil deposits by the injection of a drilling fluid in admixture with a chemical solution, in an environment adjacent to the bore hole. With a view to increasing the final recovery factor, into the environment adjacent to the bore hole there is injected a unique system in a concentration of 3...4% by weight in relation to the water in the deposit, the solution comprising alkylbenzenesulphonic acid, sodium hydroxide, oxygenated water and phosphoric acid, which, within at least 3 days shall start a limited internal combustion with pressure and thermal gradient increase in the deposit layer, leading to the release of raw organic material and iron oxides with an increase of formation permeability.</p> |
