Method for producing oil by in situ combustion with optimum steam injection
Patent
·
OSTI ID:5556790
In a method for producing oil from a subterranean formation by forward in situ combustion combined with optimum steam injection, a forward in situ combustion front is passed by a flow of air through a formation between input and output wells. Injection of steam with the air is begun when the combustion front is stabilized, and before the front-traversed formation is sufficiently cooled that the injected steam is condensed into a liquid bank of water. About 240 bbl of water converted into steam are used for each 1 Mscf of air concurrently injected into the formation. Steam injection ends when steam is produced with the displaced oil through the output well. (3 claims)
