Abstract
The present invention relates to systems, apparatuses, and methods for providing a reliable, high purity source of CO2 that is used in the recovery of formation deposits, such as fossil fuels. At least a portion of the fossil fuels recovered may be directly combusted or extracted using the same process used to provide the pure source of CO2 without the need to first remove CO2, sulfur, other fossil fuels, or other impurities.
Claims61
A method for recovering a fuel material deposit from a formation, the method comprising:
- providing a combustion fuel and an oxidant into a transpiration cooled combustor;
- combusting the combustion fuel to provide a CO2 containing stream comprising supercritical CO2;
- and
- injecting at least a portion of the CO2 containing stream into the formation including the fuel material deposit for recovery such that at least a portion of the fuel material in the formation and at least a portion of the CO2 stream flow from the formation and into a recovery well.
A method of producing a CO2 containing stream down-hole in a well, the method comprising:
- providing a combustion fuel and an oxidant into a transpiration cooled combustor positioned down-hole in the well that is in or around a formation including a fuel material deposit;
- providing a transpiration cooling fluid into the combustor;
- and
- combusting the fuel within the transpiration cooled combustor in the presence of the transpiration cooling fluid so as to provide a CO2 containing stream from an outlet of the combustor at a pressure of at least about 7.5 MPa and a temperature of at least about 400° C., wherein the CO2 containing stream comprises supercritical CO2.
An apparatus for producing a CO2 containing stream down-hole in a well, the apparatus comprising:
- a transpiration cooled combustor;
- a combustion fuel supply in fluid connection with the combustor;
- an oxidant supply in fluid connection with the combustor;
- a transpiration coolant supply in fluid connection with the combustor;
- a chamber within the transpiration cooled combustor wherein combustion of the fuel occurs at a temperature of at least about 600° C. to produce the CO2 containing stream;
- and
- an outlet on the combustor that delivers the CO2 containing stream from the combustor and into the well.
A system for generating CO2 and recovering a fuel material deposit from a formation, the system comprising:
- a transpiration cooled combustor;
- a combustion fuel supply in fluid connection with the combustor;
- an oxidant supply in fluid connection with the combustor;
- a transpiration coolant supply in fluid connection with the combustor;
- a chamber within the transpiration cooled combustor configured for receiving and combusting the combustion fuel to provide a CO2 containing stream comprising supercritical CO2;
- an injection component that delivers the CO2 containing stream into the formation including the fuel material deposit such that at least a portion of the fuel material in the formation and at least a portion of the CO2 stream flow from the formation and into a recovery well as a recovery stream;
- and
- one or more processing components for processing the recovered fuel material and CO2 in the recovery stream
