A method of servicing a wellbore in a subterranean formation comprising placing a foamed wellbore servicing fluid into a wellbore; flowing the foamed wellbore servicing fluid back to the wellbore surface; and contacting the foamed wellbore servicing fluid with an immobilized defoaming agent structure comprising an inert substrate and a defoamer. A system comprising a foamed wellbore servicing fluid in contact with a de-foaming structure, wherein the de-foaming structure comprises a defoamer covalently bonded to an inert substrate.

1. A method of servicing a wellbore in a subterranean formation comprising: placing a foamed wellbore servicing fluid into a wellbore;flowing the foamed wellbore servicing fluid back to the wellbore surface; andcontacting the foamed wellbore servicing fluid with an immobilized defoaming agent structure comprising an inert substrate and a defoamer. 2. The method of claim 1 wherein the inert substrate is an organic polymer, an inorganic material, or combinations thereof. 3. The method of claim 2 wherein the organic polymer is vinyl polymers, olefin polymers, fluoropolymers, polyesters, copolymers thereof, or combinations thereof. 4. The method of claim 3 wherein the vinyl polymer is polystyrene, polyvinylchloride, cross-linked polyvinylacetate, cross-linked polyacrylamide, poly methacrylamide, copolymers, blends, or combinations thereof. 5. The method of claim 3 wherein the olefin polymer is polyethylene, polypropylene, polybutylene, polybutadiene, polyisoprene, copolymers, blends, or combinations thereof. 6. The method of claim 3 wherein the fluoropolymer is polyvinyl fluoride, polytetrafluoroethylene, fluorinated ethylene propylene copolymers, perfluoroalkoxy polymer, perfluoromethylalkoxy polymer, ethylenetetrafluoroethylene, ethylenechlorotrifluoroethylene, polychlorotrifluoro ethylene, polyvinylidene fluoride, perfluoro-octene, copolymers, blends, or combinations thereof. 7. The method of claim 3 wherein the polyester is polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polymerized polyethyleneglycol dimethacrylate, copolymers, blends, or combinations thereof. 8. The method of claim 3 wherein the inorganic material is silica gel, alumina, metals, or combinations thereof. 9. The method of claim 2, wherein the de-foaming structure comprises a defoamer covalently bonded to an inert substrate. 10. The method of claim 9 wherein the defoamer is a silicon-containing material, a hydrocarbon, polypropylene glycol, polyethylene glycol, an aliphatic hydrocarbon, glycerol tristearate, amides of carboxylic acid, ethoxylated fatty alcohols, propoxylated fatty alcohols, ethoxylated alcohols, n-alkyl phosphate esters, or combinations thereof and wherein the inert substrate comprises an organic polymer, an inorganic material, or combinations thereof. 11. The method of claim 10 wherein the wellbore servicing fluid is a drilling fluid and the structure is a screen. 12. The method of claim 11 further comprising recovering a defoamed wellbore servicing fluid substantially free of the defoamer. 13. The method of claim 2 wherein the organic polymer is acrylonitrile/butadiene/styrene resins, block copolymers of styrene with either butadiene or isoprene; polysiloxane resins, polyphosphazenes, or combinations thereof. 14. The method of claim 1 wherein the defoamer is a silicon-containing material, a hydrocarbon, polypropylene glycol, polyethylene glycol, an aliphatic hydrocarbon, glycerol tristearate, amides of carboxylic acid, ethoxylated fatty alcohols, propoxylated fatty alcohols, ethoxylated alcohols, aliphatic alcohols, n-alkyl phosphate esters, or combinations thereof. 15. The method of claim 1 wherein the inert substrate, the defoamer, or both are functionalized. 16. The method of claim 1 wherein the inert substrate and the defoamer are covalently bonded. 17. The method of claim 16 wherein the covalent bond is a sulfur-metal t bond, an ester bond, an amide bond, a C—C bond, a C—O bond; a C—N bond; a C—Si bond or combinations thereof. 18. The method of claim 1 wherein the inert substrate and the defoamer are covalently bonded via a condensation reaction. 19. The method of claim 18 wherein the condensation reaction is a condensation reaction between an amine and a carboxylic acid; a condensation reaction between an alcohol and a carboxylic acid; a Claisen condensation reaction; a Claisen-Schmidt condensation reaction; a Knoevenagel condensation reaction; a Michael addition reaction; chloride condensation reaction or combinations thereof. 20. The method of claim 1 wherein the immobilized defoaming agent structure is a porous structure, a screen; a flexible sponge, or any combinations thereof. 21. The method of claim 1 wherein the defoamer covers from about 5% to about 100% of the surface of the inert substrate. 22. The method of claim 1 further comprising recovering a defoamed wellbore servicing fluid substantially free of the defoamer, re-foaming the recovered wellbore serving fluid, and placing the re-foamed wellbore servicing fluid downhole.
