PROCEDURE FOR DEVELOPMENT OF OIL-KEROGEN CONTAINING DEPOSITS Russian patent published in 2011 - IPC E21B43/24 

FIELD: oil and gas production.

SUBSTANCE: procedure consists in creation of zone of intra-formational oxidising and thermo-dynamic processes in reservoir. According to the invention oxygen containing water-air mixture is pumped into the reservoir via a pressure well. Thermo-hydro-dynamic processes are controlled with value of water-air ratio of oxygen containing mixture under condition of heating zone of the reservoir as high as 250°C. Optimal value of water-air ratio is determined from an analytic expression. Also, value of water-air ratio of pumped oxygen containing mixture is cyclically raised and dropped around an established optimal value at level of drop of the said value below 0.001 m³/nm³.

EFFECT: most efficient utilisation of heat power of oxygen oxidising in reservoir; increased level of safety of process due to elimination of oxygen occurrence in producers.
