THERMAL OIL PRODUCTION METHOD Russian patent published in 2006 - IPC E21B43/243

Abstract RU 2287054 C1

FIELD: oil production, particularly with the use of heat.

SUBSTANCE: method involves drilling vertical wells in oil-bearing reservoir; injecting water; producing oil; igniting oil-bearing reservoir; producing residual oil. Before formation ignition mixture containing 55% nitric acid and diesel fuel is supplied in oil-bearing reservoir via injection wells. The mixture contains 83.1-95% by weight of 55% nitric acid and 5-16.9% by weight of diesel fuel. After reservoir ignition residual oil is displaced from reservoir with water.

EFFECT: increased efficiency due to elimination the need of continuous oxidizing agent injection in reservoir for combustion sustaining.
