Abstract: Methods and systems related to SAGD injection and/or production wells that utilize flow distribution control devices. Additionally, methods and systems using limited vertical spacing separating the wells are described. These methods and systems improve steam assisted gravity drainage (SAGD) oil production, reduce SAGD start-up time and costs, and improve overall SAGD performance.

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.

Abstract: Methods and systems relate to steam assisted gravity drainage (SAGD) utilizing well pairs that are at least initially in fluid communication through drilled bores toward their toe ends. At least one of a horizontal injection well and horizontal production well of such a well pair includes a hooked length toward toe ends of each other connecting said injection well and said production well. The methods and systems improve SAGD oil production, reduce SAGD start-up time and costs, and improve overall SAGD performance.
