Abstract

A method of mitigating annular pressure buildup includes providing or using a foamed treatment fluid including: an aqueous base fluid; a water-soluble polymer comprising carbonyl groups; an organic crosslinking agent that comprises an amine group that is capable of crosslinking the water-soluble polymer comprising carbonyl groups; a foam surfactant; and sufficient gas to form a foam; and introducing the foamed treatment fluid into a well bore annulus. A foamed treatment fluid includes an aqueous base fluid; a water-soluble polymer comprising carbonyl groups; an organic crosslinking agent that comprises an amine group that is capable of crosslinking the water-soluble polymer comprising carbonyl groups; a foam surfactant; and sufficient gas to form a foam.

First claim

What is claimed is:

1. A method of mitigating annular pressure buildup comprising:
providing or using a foamed treatment fluid including:
an aqueous base fluid;
a water-soluble polymer comprising carbonyl groups comprising at least one of an acrylamide-based polymer, an oxidized polysaccharide, and combinations thereof;
an organic crosslinking agent comprising polyethyleneimine, wherein the organic crosslinking agent is present in an amount of about 0.5% to about 15% by weight of the foaming treatment fluid;
a foam surfactant; and
sufficient gas to form a foam; and

introducing the foamed treatment fluid into a well bore annulus.

2. The method of claim 1 , wherein the foamed treatment fluid includes no chromium crosslinking agents.

3. The method of claim 1 , wherein the foamed treatment fluid further comprises a gelling agent.

4. The method of claim 3 , wherein the gelling agent is a biopolymer.

5. The method of claim 1 , wherein the foam surfactant comprises at least one of an amphoteric surfactant, cationic surfactant, anionic surfactant, and combinations thereof.

6. The method of claim 5 , wherein the foam surfactant comprises at least one selected from the group consisting of betaines, sultaines, and imidazolinium, sodium lauryl sulfate, polyoxyethylene fatty alcohols, polyoxyethylene sorbitol esters, alkanolamides, sulfosuccinates, phospholipids, glycolipid, sodium lauryl sulfoacetate, alcohol ether sulfates, and combinations thereof.

7. The method of claim 1 , wherein the foam surfactant is present in the foamed treatment fluid at a concentration of about 0.005% to about 5% w/w of the aqueous base fluid.

8. The method of claim 1 , wherein the quality of the foam is from about 5% gas volume to about 99% gas volume.

9. The method of claim 1 , wherein the gas is selected from the group consisting of nitrogen, carbon dioxide, air, methane, helium, argon, and any combination thereof.

10. The method of claim 1 , further comprising using the treatment fluid to displace a drilling fluid from the well bore annulus; and introducing a cement composition into the well bore annulus, wherein the treatment fluid separates the cement composition from the drilling fluid.

11. A method of mitigating annular pressure buildup comprising:
combining:
an aqueous base fluid;
a water-soluble polymer comprising dialdehyde starch, dialdehyde cellulose, or combinations thereof;
an organic crosslinking agent comprising polyethyleneimine;
a foam surfactant; and
sufficient gas to form a foam; and

introducing the foamed treatment fluid into a well bore annulus.

12. The method of claim 11 , wherein the water-soluble polymer further comprises at least one of the following: an acrylamide-based polymer, an oxidized polysaccharide, and combinations thereof.

13. The method of claim 11 , wherein the foamed treatment fluid includes no chromium crosslinking agents.

14. The method of claim 11 , wherein the foamed treatment fluid further comprises a gelling agent.

15. The method of claim 14 , wherein the gelling agent is a biopolymer.

16. The method of claim 11 , wherein the foam surfactant comprises at least one of an amphoteric surfactant, cationic surfactant, anionic surfactant, and combinations thereof.

17. The method of claim 16 , wherein the foam surfactant comprises at least one selected from the group consisting of betaines, sultaines, and imidazolinium, sodium lauryl sulfate, polyoxyethylene fatty alcohols, polyoxyethylene sorbitol esters, alkanolamides, sulfosuccinates, phospholipids, glycolipid, sodium lauryl sulfoacetate, alcohol ether sulfates, and combinations thereof.

18. The method of claim 11 , wherein the foam surfactant is present in the foamed treatment fluid at a concentration of about 0.005% to about 5% w/w of the aqueous base fluid.

19. The method of claim 11 , wherein the quality of the foam is from about 5% gas volume to about 99% gas volume.

20. The method of claim 11 , wherein the gas is selected from the group consisting of nitrogen, carbon dioxide, air, methane, helium, argon, and any combination thereof.

21. The method of claim 11 , further comprising using the treatment fluid to displace a drilling fluid from the well bore annulus; and introducing a cement composition into the well bore annulus, wherein the treatment fluid separates the cement composition from the drilling fluid.

22. The method of claim 11 , further comprising a mixer for combining the components and a pump for introducing the foamed treatment fluid into the well bore annulus.
