The liquid may be a dipolar molecular liquid, and may be pressurized... | 03/18/2008 |
| 7341102 | Flue gas injection for heavy oil recovery A variety of methods for thermal recovery of natural gas and bitumen from a formation containing the latter. In general, the methods incorporate a series of existing, but previously uncombined technologies. A modified flue gas from the steam generators conventionall... | 03/11/2008 |
| 7338924 | Oil-in-water-in-oil emulsion An oil-in-water-in-oil emulsion (O/W/O) comprising a first oil-in-water emulsion dispersed in a second oil, and a method of preparing the same. The O/W/O emulsion can be used as a drive fluid in an enhanced oil recovery process. The O/W/O emulsion of this invention ... | 03/04/2008 |
| 7279017 | Method for converting heavy oil residuum to a useful fuel A method for enabling the use of heavy oil residuum by conversion to a useful product. The method, in one embodiment, involves the use of a heavy oil residuum which is substantially non flowable. The viscosity of the residuum is reduced by heat or a combination of h... | 10/09/2007 |
| 7186673 | Stability enhanced water-in-oil emulsion and method for using same A method for enhancing the stability of a water-in-oil emulsion pretreating at least a portion of the oil prior to emulsification. The pretreatment step may consist of adding polymers to the oil, biotreating the oil, photochemically treating the oil, or combinations... | 03/06/2007 |
| 7121339 | Solids-stabilized oil-in-water emulsion and a method for preparing same A solids-stabilized oil-in-water emulsion and a method for preparing the solids-stabilized oil-in-water emulsion. The oil-in-water emulsion is formed by combining oil, water, solid particles and a pH enhancing agent and mixing until the solid-stabilized oil-in-water... | 10/17/2006 |
| 6384091 | Emulsion with coke additive in hydrocarbon phase and process for preparing same A process for preparing a hydrocarbon in water emulsion includes the steps of providing a hydrocarbon phase containing inactive natural surfactant; mixing a solid carbon additive with the hydrocarbon phase, the solid additive being selected from the group... | 05/07/2002 |
| 6197837 | Method for fluidizing tars A process for the preparation of an aqueous tar suspoemulsion includes the steps of mixing a mixture including (a) a viscous tar composition formed from a tar, from inorganic solids and, optionally, from water; (b) water (W); (c) a surface-active agent (S... | 03/06/2001 |
| 6069178 | Emulsion with coke additive in hydrocarbon phase and process for preparing same A process for preparing a hydrocarbon in water emulsion includes the steps of providing a hydrocarbon phase containing inactive natural surfactant; mixing a solid carbon additive with the hydrocarbon phase, the solid additive being selected from the group... | 05/30/2000 |
