Abstract:
A continuous method of in situ steam generation for steamflooding which comprises injecting a mixture of hydrocarbons to serve as fuel for in situ combustion and water to be converted into steam by the hot formation into an upper zone of the formation, while simultaneously injecting into the lower zone an oxidant causing at least a portion of the oxidant to contact and combust with the injected hydrocarbons.
