Patent number: 8333895Abstract: A pond receives a flow of contaminated water into the pond substantially tangential to a volume of clarified water which is stored in the pond and which is largely quiescent. The tangential inflow overcomes a large rotational inertia in the stored volume of clarified water and establishes a slow spiral flow path about the periphery of the pond and inwards to a central outlet. The clarified stored water is discharged ahead of the inflowing contaminated water increasing the residence time of the contaminated water in the pond and permitting contaminants to receive at least partial treatment, such as settling of sediment, in the pond.Type: GrantFiled: May 19, 2010Date of Patent: December 18, 2012Inventors: Cory Albers, Bernard Amell

Patent number: 8333239Abstract: A burner with a casing seal is used to create a combustion cavity at a temperature sufficient to reservoir sand. The burner creates and sustains hot combustion gases at a steady state for flowing into and permeating through a target zone. The casing seal isolates the combustion cavity from the cased wellbore and forms a sealed casing annulus between the cased wellbore and the burner. Water is injected into the target zone, above the combustion cavity, through the sealed casing annulus. The injected water permeates laterally and cools the reservoir adjacent the wellbore, and the wellbore from the heat of the hot combustion gases. The hot combustion gases and the water in the reservoir interact to form a drive front in a hydrocarbon reservoir.Type: GrantFiled: January 14, 2010Date of Patent: December 18, 2012Assignee: Resource Innovations Inc.Inventors: Fred Schneider, Lynn P. Tessier

Patent number: 8197676Abstract: A tailings solvent recovery vessel substantially without conventional internals utilizes nozzles for forming very fine solvent-containing hydrocarbon droplets from a solvent-containing tailings feedstream. The hydrocarbon droplets are discrete from water droplets. The hydrocarbon droplets are small enough to result in a large surface area and a desired fall residence time but sufficiently large that they are not entrained with the rising vapor in the vessel. The feedstream is introduced to the vessel with a pressure drop to result in an initial flashing of the solvent from the solvent-containing droplets. Heat from the vessel atmosphere or from steam flowing countercurrent to the falling hydrocarbon droplets is transferred to the falling hydrocarbon droplets resulting in vaporization of any residual solvent therefrom. A substantially solvent-depleted pool is collected in the bottom of the vessel and retained only so long as is required to pump the underflow stream from the vessel.Type: GrantFiled: May 7, 2009Date of Patent: June 12, 2012Assignee: Total E&P Canada LtdInventor: Jianmin Kan
