Abstract

A system and a method for recovering hydrocarbons from a reservoir containing hydrocarbons, by in-situ combustion. The system includes a primary liquid production wellbore having a substantially horizontal primary production length extending through the reservoir, a vent well in fluid communication with the reservoir at a venting position which is relatively higher in the reservoir than the primary production length, an injector apparatus in fluid communication with the reservoir along an injection line in the reservoir which is relatively higher in the reservoir than the primary production length and relatively lower in the reservoir than the venting position, and an injection gas source connected with the injector apparatus. The method includes providing the system, injecting an injection gas containing oxygen into the reservoir to cause combustion of hydrocarbons contained in the reservoir, producing hydrocarbon liquid from the primary liquid production wellbore, and venting combustion gases from the vent well.
