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 structur
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 system comprising: a first volume of a foamed wellbore servicing fluid recovered from a wellbore and in contact with a de-foaming structure, wherein the defoaming structure comprises a defoamer and an inert substrate. 2. The system of claim 1, wherein the defoaming structure is a porous structure, a screen, a flexible sponge, or combinations thereof. 3. The system of claim 1, wherein the defoaming structure comprises a screen. 4. The system of claim 1, further comprising a fluid container, wherein at least a portion of the fluid container comprises the defoaming structure. 5. The system of claim 4, wherein the fluid container comprises a median or baffle, wherein at least a portion of the median or baffle comprises the defoaming structure. 6. The system of claim 1, further comprising a fluid conduit, wherein at least a portion of the fluid conduit comprises the defoaming structure. 7. The system of claim 6, wherein the fluid conduit is a pipe. 8. The system of claim 1, further comprising a wellbore servicing equipment component. 9. The system of claim 8, wherein at least a portion of the wellbore servicing equipment component comprises the defoaming structure. 10. The system of claim 1, further comprising a second volume of the foamed wellbore servicing fluid disposed within the wellbore. 11. The system of claim 1, further comprising a recovered defoamed wellbore servicing fluid substantially free of the defoamer. 12. The system of claim 11, 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 is selected from the group consisting of an organic polymer, an inorganic material, and combinations thereof. 13. The system 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, n-alkyl phosphate esters, or combinations thereof and wherein the inert substrate is an organic polymer, an inorganic material, or combinations thereof. 14. The system of claim 1, wherein the inert substrate is an organic polymer an inorganic material, or combinations thereof. 15. The system of claim 1, wherein the inert substrate, the defoamer, or both are functionalized. 16. The system of claim 1, wherein the defoamer is bonded to the inert substrate via a covalent bond. 17. The system 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 system of claim 1, wherein the inert substrate and the defoamer are bonded via a covalent bond, where the covalent bond results via a condensation reaction. 19. The system 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 system of claim 1, wherein the defoamer covers from about 5% to about 100% of the surface of the inert substrate.
