TREATMENT METHOD OF BITUMINOUS SANDS FORMATION AND TRANSPORT FUEL MADE USING THIS METHOD Russian patent published in 2012 - IPC E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: method implies: heating of at least a part of hydrocarbonaceous layer in formation using several heaters located in formation; control of heating so that average temperature of at least largest part of section reaches value within interval from 200°C to 240°C resulting in primary cracking of at least some quantity of hydrocarbons in the section; maintaining of pressure in formation within about 1 MPa lower than pressure of formation hydraulic fracture; and extraction from formation of at least some quantity of hydrocarbons resulting in primary cracking, at that, before heating in formation, gas cap is made to prevent rapid increase of pressure during thermal treatment up to pressure of hydraulic fracture, to maintain quality of production front of displacement process and to provide possibility to reduce power of heaters in mentioned gas cap. This heating method is used upon transport fuel production.

EFFECT: increasing production efficiency due to possibility of formations heating control.
