Abstract
Embodiments of the invention described herein relate to methods and apparatus for recovery of viscous hydrocarbons from subterranean reservoirs. In one embodiment, a method for recovery of hydrocarbons from a subterranean reservoir is provided. The method includes drilling an injector well to be in communication with a reservoir having one or more production wells in communication with the reservoir, installing casing in the injector well, cementing the casing, perforating the casing, positioning a downhole steam generator in the casing, flowing fuel, oxidant and water to the downhole steam generator to intermittently produce a combustion product and/or a vaporization product in the reservoir, flowing injectants to the reservoir, and producing hydrocarbons through the one or more production wells.
