Abstract

A method of servicing a wellbore in a subterranean formation comprising placing a wellbore servicing fluid comprising a resin-loaded expanded material into a wellbore wherein a resin is released from the resin-loaded expanded material in situ within the wellbore or subterranean formation. A wellbore treatment composition comprising a resin-loaded expanded material wherein the expanded material comprises polylactide and the resin material comprises a high-temperature epoxy-based resin.

First claim

What is claimed is:

1. A method of servicing a wellbore in a subterranean formation comprising:
adding a liquid additive to a wellbore servicing fluid, wherein the liquid additive comprises a resin-loaded expanded material that comprises a resin and an expanded material comprising a foam; and
placing the wellbore servicing fluid into the wellbore,
wherein the resin is released from the resin-loaded expanded material in situ within the wellbore or the subterranean formation, and
wherein the resin at least partially coats a proppant in situ within the wellbore or the subterranean formation after being released.

2. The method of claim 1 wherein the foam is selected from the group consisting of: a hydrocarbon-based material, a degradable material, and any combination thereof.

3. The method of claim 1 wherein the foam comprises an open-cell structure foam or a closed-cell structure foam.

4. The method of claim 2 wherein the foam is the hydrocarbon-based material, and wherein the hydrocarbon-based material is selected from the group consisting of: polyethylene, polypropylene, polystyrene, a hydrocarbon-based rubber (e.g., latex), any copolymer, any blend, any derivative thereof, and any combination thereof.

5. The method of claim 2 wherein the hydrocarbon-based material is the degradable material, and wherein the degradable material comprises a degradable polymer.

6. The method of claim 5 wherein the degradable polymer is selected from the group consisting of: a polysaccharide, a lignosulfonate, a chitin, a chitosan, a protein, a proteinous material, a fatty alcohol, a fatty ester, a fatty acid salt, an aliphatic polyester, a poly(lactide), a poly(glycolide), a poly(ϵ-caprolactone), a polyoxymethylene, a polyurethane, a poly(hydroxybutyrate), a poly(anhydride), an aliphatic polycarbonate, a polyvinyl polymer, an acrylic-based polymer, a poly(amino acid), a poly(aspartic acid), a poly(alkylene oxide), a poly(ethylene oxide), a polyphosphazene, poly(orthoester), a poly(hydroxy ester ether), a polyether ester, a polyester amide, a polyamide, a polyhydroxyalkanoate, a polyethyleneterephthalate, a polybutyleneterephthalate, a polyethylenenaphthalenate, any copolymer, any blend, any derivative, and any combination thereof.

7. The method of claim 6 wherein the degradable polymer is the aliphatic polyester, and wherein the aliphatic polyester comprises a compound represented by general formula I:

where n is an integer ranging from about 75 to about 10,000 and R comprises hydrogen, an alkyl group, an aryl group, an alkylaryl group, an acetyl group, a heteroatom, and any combination thereof.

8. The method of claim 5 wherein the degradable polymer comprises polylactic acid.

9. The method of claim 1 wherein the expanded material has a porosity of from about 20 vol. % to about 90 vol. %.

10. The method of claim 1 wherein the expanded material has a pore size of from about 0.1 microns to about 500 microns.

11. The method of claim 1 wherein the expanded material has a bulk density of from about 0.05 g/cc to about 1 g/cc.

12. The method of claim 1 wherein the resin is selected from the group consisting of: a thermoplastic resin, an acrylic-based resin, a two-component epoxy-based resin, a furan-based resin, a phenolic-based resin, a high-temperature epoxy-based resin, a phenol/phenol formaldehyde/furfuryl alcohol resin, a polysilicone, a polyepoxide resin, a polyester resin, an urea-aldehyde resin, an urethane resin, and any combination thereof.

13. The method of claim 1 wherein the resin is present in an amount of from about 0.1 wt. % to about 99 wt. % and the expanded material is present in an amount of from about 0.1 wt. % to about 99 wt. % based on the total weight of the resin-loaded expanded material.

14. The method of claim 1 wherein the resin-loaded expanded material is present in the wellbore servicing fluid in an amount of from about 0.01 ppg to about 6 ppg.

15. The method of claim 1 wherein the wellbore servicing fluid is a fracturing fluid.

16. The method of claim 1 further comprising altering the structural integrity of the resin-loaded expanded material.

17. The method of claim 16 wherein the structural integrity of the resin-loaded expanded material is altered by compression, contact with a degradation agent, or both.

18. The method of claim 17 wherein the degradation agent comprises a solution selected from the group consisting of: a base solution, an ammonium hydroxide solution, an alcoholic alkaline solution, an alkaline amine solution, and any combination thereof.

19. The method of claim 1 wherein the wellbore servicing fluid comprises the proppant.

20. The method of claim 1 wherein the resin at least partially coats the proppant in situ within a fracture in the subterranean formation.
