FIELD: hydrocarbon, hydrogen and/or other product extraction methods and systems, particularly enhanced recovery methods thereof with the use of heat, namely in-situ hydrocarbon conversion.
SUBSTANCE: method for in-situ hydrocarbon reservoir treatment involves supplying heat from one or several sources to at least one reservoir section, wherein heat sources may include natural distributed combustion chamber. Natural distribution combustion chamber comprises oxidizing fluid source to supply oxidizing fluids to reaction reservoir zone for heat generation in reaction zone. Heat is transferred from reaction zone to selected transversal reservoir section so that heat from one or several heat sources provide pyrolysis of at least one part of hydrocarbons in selected zone. Hydrocarbons are produced from said reservoir.
EFFECT: increased method efficiency and production system reliability.
