ELECTRIC AND FIRED STEAM GENERATION SYSTEMS

摘要

Methods and systems relate to steam assisted oil recovery utilizing a fired boiler and an electric boiler, which may be disposed closer to an injection well than the fired boiler. A gas turbine produces electricity supplied to the electric boiler and flue gas exhaust that may input into the fired boiler. The electric boiler may vaporize condensate that forms from the steam generated in the fired boiler prior to being introduced into the injection well.

主权项

1. A method of steam assisted oil recovery with dual steam generation, comprising:
producing electricity with an onsite gas turbine; generating steam with a fired boiler at a first location; conveying the steam to a second location resulting in a mixture formed of the steam and condensate caused by heat loss during the conveying; separating the steam from the condensate in the mixture; heating the condensate in an electric boiler powered by the electricity from the gas turbine to convert the condensate back to a vapor phase combined with the steam separated from the condensate to provide a combined steam flow; and introducing the combined steam flow into a formation for the steam assisted oil recovery.
