TREATMENT METHOD OF HYDROCARBON-BEARING FORMATIONS USING NON-UNIFORMLY LOCATED HEAT SOURCES Russian patent published in 2013 - IPC E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: according to the proposed method, heat is supplied from one or more heat sources located in the first section of the formation to the first section of the formation. Heat is supplied to the formation from heat sources so that heat supply to the formation per unit volume of the formation for the first volume of the first section is less than heat supply to the formation per unit volume of the formation for the second volume of the first section, and heat supply to the formation per unit volume of the formation for the second volume of the first section is less than heat supply to the formation per unit volume of the formation for the third volume of the first section. The first volume envelopes a production well located in the centre of the section or near that centre; the second volume envelopes the first volume, and the third volume envelopes the second volume. Fluids are extracted from the first section through the production well.

EFFECT: improving the effectiveness of the treatment method due to power supply optimisation.
