| titleOfInvention | Open surface flotation method for extracting crude oil |
| abstract | INVENTION: OPEN SURFACE FLOTATION METHOD INVENTORS: DAN BASS GOLDEN, COLORADO FUN-DEN WANG LAKEWOOD, COLORADO ATTORNEY: ROBERT L. SLATER, JR. NEW YORK, NEW YORK 10005 (212) 425-3158 ABSTRACT A method for the in situ separation of viscous crude oil from a reservoir such as oil shale, oil sand, or tar sand is disclosed. Hot water is introduced to the top surface of the reservoir while steam is injected into the reservoir through drill holes. The hot water and steam may contain a surfactant. The bouyancy of the crude oil creates an artificial water drive which causes the water and oil to "flip-flop' so that the oil rises to the top of the reservoir and separates from the remainder of the reservoir mat-erial. If the overburden is deep, underground mining techniques may be used to reach the reservoir prior to applying the present method. |
