Abstract

A downhole tool, and method of using the downhole tool, for enhancing recovery of heavy oil from a formation. The downhole tool includes an outer core having at least one ceramic portion. At least one electromagnetic antenna is disposed within the outer core. The at least one electromagnetic antenna is operable to emit electromagnetic radiation to heat the at least one ceramic portion.

First claim

What is claimed is:

1. A downhole tool for enhancing recovery of heavy oil from a formation, the downhole tool comprising:
an outer core having at least one ceramic portion, the at least one ceramic portion comprising a heat up ceramic material, the heat up ceramic material comprising at least three compounds selected from the group consisting of: silica, alumina, magnesium oxide, potassium iron III oxide, calcium oxide, sodium oxide, and titanium oxide; and
at least one electromagnetic antenna located proximate the at least one ceramic portion; wherein
the at least one electromagnetic antenna is operable to emit electromagnetic radiation that is capable of heating the at least one ceramic portion, and the at least one ceramic portion operable to heat quickly such that steam is generated in situ in the formation when the at least one ceramic portion contacts water.

2. The downhole tool of claim 1 , wherein the at least one ceramic portion comprises at least one solid ceramic portion.

3. The downhole tool of claim 1 , wherein the at least one ceramic portion comprises at least one mesh ceramic portion.

4. The downhole tool of claim 3 , wherein the downhole tool further comprises an inner core that is operable to allow the flow of fluid.

5. The downhole tool of claim 1 , wherein the at least one ceramic portion is operable to be heated to at least about 1000° C. by the electromagnetic radiation emitted from the at least one electromagnetic antenna.

6. The downhole tool of claim 1 , wherein the electromagnetic radiation frequency ranges from 300 MHz to 300 GHz.

7. The downhole tool of claim 1 , further comprising a connector for selectively attaching the downhole tool to a string for removeably lowering the downhole tool into a wellbore.

8. The downhole tool of claim 1 , wherein the at least one electromagnetic antenna is operable to emit electromagnetic radiation that is capable of heating the at least one ceramic portion in between about 3 minutes and about 5 minutes, such that steam is generated in situ in the formation when the at least one ceramic portion contacts water.

9. A downhole tool for enhancing recovery of heavy oil from a formation, the downhole tool comprising:
an outer core comprising at least one mesh ceramic portion and at least one solid ceramic portion, the at least one mesh ceramic portion and at least one solid ceramic portion comprising a heat up ceramic material, the heat up ceramic material comprising at least three compounds selected from the group consisting of: silica, alumina, magnesium oxide, potassium iron III oxide, calcium oxide, sodium oxide, and titanium oxide; and
at least one electromagnetic antenna; wherein the at least one electromagnetic antenna is operable to emit electromagnetic radiation that is capable of heating the at least one mesh ceramic portion and the at least one solid ceramic portion, the at least one mesh ceramic portion and at least one solid ceramic portion operable to heat quickly such that steam is generated in situ in the formation when water contacts either the at least one mesh ceramic portion or the at least one solid ceramic portion.

10. The downhole tool of claim 9 , wherein the at least one mesh ceramic portion is operable to be heated to at least about 1000° C. by the electromagnetic radiation emitted from the at least one electromagnetic antenna.

11. The downhole tool of claim 9 , wherein the at least one solid ceramic portion is operable to be heated to at least about 1000° C. by the electromagnetic radiation emitted from the at least one electromagnetic antenna.

12. The downhole tool of claim 9 , wherein the at least one mesh ceramic portion and the at least one solid ceramic portion are comprised of the same material.

13. The downhole tool of claim 9 , wherein the at least one mesh ceramic portion and the at least one solid ceramic portion are comprised of different materials.

14. The downhole tool of claim 9 , wherein the at least one mesh ceramic portion is operable to allow for the flow of fluid to the formation.

15. The downhole tool of claim 14 , wherein the fluid is water.

16. The downhole tool of claim 15 , wherein the water converts from liquid form to steam as the water flows through the at least one mesh ceramic portion to the formation.

17. The downhole tool of claim 9 , wherein the electromagnetic radiation frequency ranges from 300 MHz to 300 GHz.

18. The downhole tool of claim 9 , further comprising a connector for selectively attaching the downhole tool to a string for removeably lowering the downhole tool into a wellbore.

19. The downhole tool of claim 9 , wherein the at least one electromagnetic antenna is operable to emit electromagnetic radiation that is capable of heating the at least one mesh ceramic portion and at least one solid ceramic portion in between about 3 minutes and about 5 minutes, such that steam is generated in situ in the formation when water contacts the at least one mesh ceramic portion or the at least one solid ceramic portion.
