Abstract:
Methods and systems relate to recovering hydrocarbons with an injection well placed at a bottom of a reservoir some horizontal distance from a producer, such that the injection well and producer may both be in a common horizontal plane. For some embodiments, the process includes co-injection of steam with a non-condensable gas, such as methane, ethane, propane, carbon dioxide, combustion products and combinations thereof. The non-condensable gas provides additional solution gas drive while the location of the injection well beside, instead of above, the producer increases production time before a steam chamber reaches a top of the reservoir, increasing thermal and recovery efficiency of the process.
