Abstract

The disclosure provides a downhole tool, and method of using the downhole tool, for enhancing recovery of heavy oil from a formation. A method for enhancing recovery of heavy oil from a formation includes placing a downhole tool in a first wellbore. The downhole tool has an outer core having at least one ceramic portion and at least one electromagnetic antenna located within the outer core. Electromagnetic radiation is emitted from the at least one electromagnetic antenna to heat the at least one ceramic portion.

First claim

What is claimed is:

1. A method for enhancing recovery of heavy oil from a formation, comprising the steps of:
suspending a downhole tool with a connector above a first wellbore;
removeably lowering the downhole tool in the first wellbore, the downhole tool comprising an outer core having at least one ceramic portion, the at least one ceramic portion comprising at least one mesh ceramic portion and at least one solid ceramic portion,
the downhole tool further comprising an inner core,
and at least one electromagnetic antenna disposed between the inner core and the outer core;
injecting fluid into the inner core of the downhole tool through the wellbore;
allowing the fluid to flow from the inner core through the at least one mesh ceramic portion of the downhole tool; and
emitting electromagnetic radiation from the at least one electromagnetic antenna to heat the at least one ceramic portion.

2. The method of claim 1 , further comprising converting the fluid from liquid to steam as it flows through the at least one mesh ceramic portion.

3. The method of claim 1 , wherein the fluid is water.

4. The method of claim 1 , wherein the step of heating the at least one ceramic portion comprises heating the at least one ceramic portion to at least about 1000° C.

5. The method of claim 1 , wherein the step of emitting electromagnetic radiation comprises emitting electromagnetic radiation with frequency ranges from 300 MHz to 300 GHz.

6. The method of claim 1 , the method further comprising:
converting the fluid from liquid to steam as it flows through the at least one mesh ceramic portion;
placing production tubing in a second wellbore below the first wellbore;
reducing the viscosity of heavy oil located in the formation with the steam to produce a reduced viscosity heavy oil;
draining the reduced viscosity heavy oil to a region containing the second wellbore; and
flowing the reduced viscosity heavy oil into the production tubing to be produced from the formation.

7. The method of claim 1 , wherein the at least one ceramic portion comprises silica, alumina, magnesium oxide, potassium, iron III oxide, calcium oxide, sodium oxide, and titanium oxide.

8. The method of claim 1 , the method further comprising:
injecting a proppant comprising ceramic particles into the inner core; and
heating the ceramic particles in the proppant with the electromagnetic radiation from the at least one electromagnetic antenna as the proppant flows from the inner core through the at least one mesh ceramic portion to the formation.

9. The method of claim 8 , wherein the ceramic particles range in size from about 106 micrometers to about 2.36 millimeters.

10. The method of claim 8 , wherein the ceramic particles are less than 2 micrometers.

11. A method for enhancing recovery of heavy oil from a formation, comprising the steps of:
suspending a downhole tool with a connector above a wellbore;
removeably lowering the downhole tool in the wellbore, the downhole tool comprising an inner core that is operable to allow the flow of fluid, an outer core comprising at least one mesh ceramic portion and at least one solid ceramic portion, and at least one electromagnetic antenna disposed between the inner core and outer core;
emitting electromagnetic radiation from the at least one electromagnetic antenna to heat the at least one mesh ceramic portion and the at least one solid ceramic portion to a temperature higher than the boiling point of the fluid;
injecting the fluid into the inner core;
flowing the fluid from the inner core through the at least one mesh ceramic portion to the formation; and
converting the fluid to steam as it flows through the at least one mesh ceramic portion.

12. The method of claim 11 , wherein the fluid is water.

13. The method of claim 11 , wherein the step of heating the at least one mesh ceramic portion and the at least one solid ceramic portion comprises heating the at least one mesh ceramic portion and the at least one solid ceramic portion to at least about 1000° C.

14. The method of claim 11 , wherein the step of emitting electromagnetic radiation comprises emitting electromagnetic radiation with frequency ranges from 300 MHz to 300 GHz.

15. The method of claim 11 , further comprising:
placing production tubing in a second wellbore below the first wellbore;
reducing the viscosity of heavy oil located in the formation with the steam to produce a reduced viscosity heavy oil;
draining the reduced viscosity heavy oil to a region containing the second wellbore; and
flowing the reduced viscosity heavy oil into the production tubing to be produced from the formation.

16. The method of claim 11 , wherein the at least one ceramic portion comprises silica, alumina, magnesium oxide, potassium, iron III oxide, calcium oxide, sodium oxide, and titanium oxide.

17. The method of claim 11 , further comprising:
injecting a proppant comprising ceramic particles into the inner core; and
heating the ceramic particles in the proppant with the electromagnetic radiation from the at least one electromagnetic antenna as the proppant flows from the inner core through the at least one mesh ceramic portion to the formation.

18. The method of claim 17 , wherein the ceramic particles range in size from about 106 micrometers to about 2.36 millimeters.

19. The method of claim 17 , wherein the ceramic particles are less than 2 micrometers.
