Abstract

The invention discloses a method of creating a polymerized composition in a well bore: providing a polymerizable composition made of a polymerization initiator and a monomer polymerizable by frontal polymerization; introducing the polymerizable composition into the wellbore; exposing the polymerizable composition to a trigger to activate the frontal polymerization; and creating the polymerized composition.

Claims (46)

1. A method of creating a polymerized composition in a well bore, comprising:

a. providing a polymerizable composition made of a polymerization initiator and a monomer polymerizable by frontal polymerization;

b. introducing the polymerizable composition into the wellbore;

c. exposing the polymerizable composition to a trigger to activate the frontal polymerization; and

d. creating the polymerized composition.

2. The method of claim 1 , wherein the trigger is temperature, electromagnetic radiation, or a chemical activator distinct from the monomer and/or initiator.

3. The method of claim 2 , wherein the electromagnetic radiation is UV or visible light.

4. The method of claim 2 , wherein the electromagnetic radiation is microwave.

5. The method of claim 1 , further comprising introduction a downhole tool in the wellbore, and wherein the trigger is generated from the downhole tool.

6. The method of claim 5 , wherein the frontal polymerization is stopped by thermal modification, by acoustic waves, by mixing the polymerizable composition or by cavitation.

7. The method of claim 1 , further comprising stopping the frontal polymerization.

8. The method of claim 7 , wherein the frontal polymerization is re-started by exposing the polymerizable composition to the trigger.

9. The method of claim 1 , wherein the polymerizable composition further comprises a thickening agent.

10. The method of claim 1 , wherein the polymerizable composition further comprises a filler.

11. The method of claim 10 , wherein the filler is a microwave susceptor.

12. The method of claim 1 , wherein the polymerized composition is solid.

13. The method of claim 1 , wherein the wellbore comprises particulates and the polymerized composition is fused with the particulates creating a screen.

14. The method of claim 13 , wherein the screen is permeable.

15. The method of claim 13 , wherein the particulates are proppant and/or gravel.

16. The method of claim 1 , wherein the polymerized composition is a plug.

17. The method of claim 16 , being used in conjunction with a method of cementing the wellbore, a method of fracturing the wellbore, or a method of drilling the wellbore.

18. The method of claim 1 , wherein the polymerized composition is a layer.

19. The method of claim 18 , being used in conjunction with a method of drilling the wellbore, a method of fracturing the wellbore, a method of perforating the wellbore, or a method of cementing the wellbore.

20. A method, comprising:

a. providing a polymerizable composition made of a polymerization initiator and a monomer polymerizable by frontal polymerization;

b. introducing the polymerizable composition into a wellbore; and

c. exposing the polymerizable composition to a trigger to activate the frontal polymerization.

21. The method of claim 20 , wherein the trigger is temperature, electromagnetic radiation, or a chemical activator distinct from the monomer and/or initiator.

22. The method of claim 21 , wherein the electromagnetic radiation is UV or visible light.

23. The method of claim 21 , wherein the electromagnetic radiation is microwave.

24. The method of claim 20 , further comprising introduction a downhole tool in the wellbore, and wherein the trigger is generated from the downhole tool.

25. The method of claim 20 , wherein the polymerizable composition further comprises a thickening agent.

26. The method of claim 20 , wherein the polymerizable composition further comprises a filler.

27. The method of claim 26 , wherein the filler is a microwave susceptor.

28. The method of claim 20 , wherein the method is sand control, lost circulation, or zonal isolation of the subterranean formation.

29. A method of consolidating an unconsolidated zone within a subterranean formation in a well bore, comprising:

a. providing a polymerizable composition made of a polymerization initiator and a monomer polymerizable by frontal polymerization;

b. providing a downhole tool able to generate a trigger;

c. introducing the downhole tool into the wellbore in the vicinity of the unconsolidated zone;

d. introducing the polymerizable composition into the wellbore;

e. exposing the polymerizable composition to the trigger to activate the frontal polymerization; and

f. leaving a solid polymerized composition in the unconsolidated zone.

30. The method of claim 29 , wherein the downhole tool is a drilling tool and the method further comprises drilling the wellbore.

31. The method of claim 29 , wherein the trigger is temperature, electromagnetic radiation, or a chemical activator distinct from the monomer and/or initiator.

32. The method of claim 31 , wherein the electromagnetic radiation is UV or visible light.

33. The method of claim 29 , wherein the trigger is generated from the downhole tool.
