Abstract

Methods of subterranean cementing involving cement compositions comprising particulate foamed elastomers and associated methods are provided. In one embodiment, the methods comprise introducing a cement composition into a subterranean location, wherein the cement composition comprises a hydraulic cement, a particulate foamed elastomer, and an aqueous fluid; and allowing the cement composition to set in the subterranean location.

First claim

What is claimed is:

1. A method of cementing, comprising:
introducing a cement composition into a subterranean location, wherein the cement composition comprises:
a hydraulic cement,
a particulate foamed elastomer, and
an aqueous fluid; and

allowing the cement composition to set in the subterranean location.

2. The method of claim 1 wherein the particulate foamed elastomer comprises polyurethane foam.

3. The method of claim 1 wherein the particulate foamed elastomer comprises a foamed swellable elastomer.

4. The method of claim 1 wherein the particulate foamed elastomer comprises at least one foamed oil-swellable elastomer selected from the group consisting of ethylene propylene diene M-class rubber, polyamide, polypropylene, polyethylene, styrene butadiene, styrene, divinylbenzene, natural rubber, acrylate butadiene rubber, polyacrylate rubber, isoprene rubber, chloroprene rubber, butyl rubber, brominated butyl rubber, chlorinated butyl rubber, chlorinated polyethylene, neoprene rubber, styrene butadiene copolymer rubber, sulphonated polyethylene, ethylene acrylate rubber, epichlorohydrin ethylene oxide copolymer, ethylene-propylene rubber, ethylene-propylene-diene terpolymer rubber, ethylene vinyl acetate copolymer, fluorosilicone rubbers, silicone rubbers, poly 2,2,1-bicyclo heptene (polynorborneane), alkylstyrene, nitrile rubber, hydrogenated nitrile rubber, fluoro rubbers, perfluoro rubbers, tetrafluorethylene/propylene, any derivative thereof, and any combination thereof.

5. The method of claim 1 wherein the particulate foamed elastomer comprises at least one foamed water-swellable elastomer selected from the group consisting of isobutylene maleic anhydride, starch-polyacrylate acid graft copolymer and salts thereof, polyethylene oxide polymer, carboxymethyl cellulose type polymers, polyacrylamide, poly(acrylic acid) and salts thereof, poly(acrylic acid-co-acrylamide) and salts thereof, graft-poly(ethylene oxide) of poly(acrylic acid) and salts thereof, poly(2-hydroxyethyl methacrylate), and poly(2-hydroxypropyl methacrylate), any derivative thereof, and any combination thereof.

6. The method of claim 1 wherein the particulate foamed elastomer is present in the cement composition in an amount of about 0.5% to about 30% by weight of the hydraulic cement.

7. The method of claim 1 wherein the particulate foamed elastomer is present in the cement composition in an amount of about 2% to about 10% by weight of the hydraulic cement.

8. The method of claim 1 wherein the particulate foamed elastomer comprises particulates with a size of about 40 to about 1000 microns.

9. The method of claim 1 wherein the hydraulic cement comprises at least one hydraulic cement selected from the group consisting of a Portland cement, a pozzolana cement, a gypsum cement, a high-alumina-content cement, a slag cement, a silica cement, cement kiln dust, and combinations thereof.

10. The method of claim 1 wherein the particulate foamed elastomer has an open cell structure that is permeable to the aqueous fluid.

11. A method of cementing in a subterranean formation, comprising:
introducing a cement composition into a space between a pipe string and a subterranean formation, wherein the cement composition comprises:
a hydraulic cement,
a particulate foamed elastomer, and
an aqueous fluid; and

allowing the cement composition to set in the space.

12. The method of claim 11 wherein the particulate foamed elastomer comprises polyurethane foam.

13. The method of claim 11 wherein the particulate foamed elastomer comprises a foamed swellable elastomer.

14. The method of claim 11 wherein the particulate foamed elastomer comprises at least one foamed oil-swellable elastomer selected from the group consisting of ethylene propylene diene M-class rubber, polyamide, polypropylene, polyethylene, styrene butadiene, styrene, divinylbenzene, natural rubber, acrylate butadiene rubber, polyacrylate rubber, isoprene rubber, chloroprene rubber, butyl rubber, brominated butyl rubber, chlorinated butyl rubber, chlorinated polyethylene, neoprene rubber, styrene butadiene copolymer rubber, sulphonated polyethylene, ethylene acrylate rubber, epichlorohydrin ethylene oxide copolymer, ethylene-propylene rubber, ethylene-propylene-diene terpolymer rubber, ethylene vinyl acetate copolymer, fluorosilicone rubbers, silicone rubbers, poly 2,2,1-bicyclo heptene (polynorborneane), alkylstyrene, nitrile rubber, hydrogenated nitrile rubber, fluoro rubbers, perfluoro rubbers, tetrafluorethylene/propylene, any derivative thereof, and any combination thereof.

15. The method of claim 11 wherein the particulate foamed elastomer comprises at least one foamed water-swellable elastomer selected from the group consisting of isobutylene maleic anhydride, starch-polyacrylate acid graft copolymer and salts thereof, polyethylene oxide polymer, carboxymethyl cellulose type polymers, polyacrylamide, poly(acrylic acid) and salts thereof, poly(acrylic acid-co-acrylamide) and salts thereof, graft-poly(ethylene oxide) of poly(acrylic acid) and salts thereof, poly(2-hydroxyethyl methacrylate), and poly(2-hydroxypropyl methacrylate), any derivative thereof, and any combination thereof.

16. The method of claim 11 wherein the particulate foamed elastomer is present in the cement composition in an amount of about 0.5% to about 30% by weight of the hydraulic cement.

17. The method of claim 11 wherein the particulate foamed elastomer is present in the cement composition in an amount of about 2% to about 10% by weight of the hydraulic cement.

18. The method of claim 11 wherein the particulate foamed elastomer comprises particulates with a size of about 40 to about 1000 microns.

19. The method of claim 11 wherein the particulate foamed elastomer comprises particulates with a size of about 60 to about 600 microns.

20. The method of claim 11 wherein the particulate foamed elastomer has an open cell structure that is permeable to the aqueous fluid.
