STEAM DRIVEN DIRECT CONTACT STEAM GENERATION
First Claim
1. A method for steam production for extraction of oil, said method comprising the steps of:
- generating steam through indirect heat exchange;
mixing said steam with liquid water having solids and organics contaminates, so as to transfer said liquid water from a liquid phase to a gas phase; and
removing solids to produce solids free gas phase steam.

Abstract
The present invention is a system and method for steam production for oil production. The method includes generating steam, mixing the steam with water containing solids and organics, separating solids, and injecting the steam through an injection well or using it above ground for oil recovery, such as for generating hot process water. The system includes a steam drive direct contact steam generator. The water feed of the present invention can be hot produced water separated from a produced oil emulsion and/or low quality water salvaged from industrial plants, such as refineries and tailings from an oilsands mine.

2. A method for steam production for oil production, said method comprising the steps of:
-
generating steam through indirect heat exchange; using the generated steam energy to directly gasify liquid water with solids and organic contaminated, so as to transfer said liquid water from a liquid phase to a gas phase; removing solids to produce solids free gas phase steam; condensing the generate steam to generate heat and water; and using the generated heat and water for oil production. - View Dependent Claims (15)
