The present invention is a method and system for treating and disposing of waste streams generated by in-situ oilsands facilities, like SAGD, and open mine oilsands extraction facilities. Fine tailings generated by the open mine extraction facility are dried and mixed with liquid concentrated brine or blow-down waste stream generated by in-situ water treatment plant. The compound solid waste can be effectively disposed of in a landfill.

The present invention is a system and method for steam production for oil extraction. The method includes generating steam, heating contaminated water and solid particles, flashing the contaminated water, separating contaminate and solid particles, and using the generated steam for oil recovery. 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.
The present invention is a system and method for steam production for oil production. The method includes generating hot driving fluid, indirectly using the hot driving fluid to heat water containing solids and organics, separating solids, and using the steam for generating hot process water or for underground injection. The system includes a non- direct contact heat exchanger connected to a separator for collecting and separating the solids from the gas. The water feed of the present invention can be water separated from produced oil and/or low quality water salvaged from industrial plants, such as refineries and tailings from an oilsands mine.
