Abstract

Methods are provided that include a method comprising providing a resin composition comprising a resin and at least a plurality of filler particulates and introducing the resin composition into a well bore which penetrates at least a portion of a subterranean formation, wherein the resin composition does not form proppant aggregates or proppant particulates. In some embodiments, the resin composition may be introduced into the subterranean formation at a pressure below the fracture pressure of the subterranean formation. Additional methods and compositions are also provided.

Claims

1. A method comprising:

providing a resin composition comprising a resin and at least a plurality of filler particulates,

wherein the resin comprises a two-component epoxy based resin comprising a liquid hardenable resin component and a liquid hardening agent component;

wherein at least a portion of the plurality of filler particulates comprises at least one filler particulate selected from the group consisting of;

alumina, zirconia, titanium dioxide, boron, and combinations of such particulates; and

,

wherein the filler is present in the resin composition from about 1% to about 10% by weight of the resin composition;

introducing the resin composition into a well bore which penetrates at least a portion of a subterranean formation, wherein the resin composition does not form proppant aggregates or proppant particulates; and

allowing the resin composition to viscosify to form a flexible material, wherein the material is able to withstand hydrostatic pressure in the well bore once it has viscosified.

2. The method of claim 1 wherein the liquid hardenable resin component comprises a hardenable resin.

3. The method of claim 2 wherein the hardenable resin is present in the liquid hardenable resin component in an amount in the range of about 5% to about 100% by weight of the liquid hardenable resin component.

4. The method of claim 1 wherein the liquid hardening agent component comprises a hardening agent and a surfactant.

5. The method of claim 4 wherein the liquid hardening agent component further comprises a silane coupling agent and a liquid carrier.

6. The method of claim 1 wherein the plurality of filler particulates have a density that is substantially similar to the resin.

7. A method comprising:

providing a resin composition comprising a resin and at least a plurality of filler particulates,

wherein the resin comprises a two-component epoxy based resin comprising a liquid hardenable resin component and a liquid hardening agent component;

wherein at least a portion of the plurality of filler particulates comprises at least one filler particulate selected from the group consisting of;

clay, alumina, carbon black, meta-silicate, calcium silicate, calcine, kaolin, talc, zirconia, titanium dioxide, boron, and combinations of such particulates, wherein the resin composition does not comprise proppant aggregates or proppant particulates;

wherein the filler is present in the resin composition from about 1% to about 10% by weight of the resin composition;

introducing the resin composition into a well bore which penetrates at least a portion of a subterranean formation at a pressure above the fracture pressure of the subterranean formation; and

allowing the resin composition to viscosify to form a flexible material, wherein the material is able to withstand hydrostatic pressure in the well bore once it has viscosified.

8. The method of claim 7 wherein the liquid hardenable resin component comprises a hardenable resin.

9. The method of claim 8 wherein the liquid hardenable resin component further comprises a solvent.

10. The method of claim 8 wherein the hardenable resin is present in the liquid hardenable resin component in an amount in the range of about 5% to about 100% by weight of the liquid hardenable resin component.

11. The method of claim 7 wherein the liquid hardening agent component comprises a hardening agent and a surfactant.

12. The method of claim 11 wherein the liquid hardening agent component further comprises a silane coupling agent and a liquid carrier.

13. A method comprising:

providing a liquid resin composition comprising a resin and at least a plurality of filler particulates dispersed therein,

wherein the resin comprises a two-component epoxy based resin comprising a liquid hardenable resin component and a liquid hardening agent component;

wherein at least a portion of the plurality of filler particulates comprises at least one filler particulate selected from the group consisting of;

alumina, zirconia, titanium dioxide, boron, and combinations of such particulates, wherein the plurality of filler particulates are intimately dispersed in the resin composition and wherein the filler particulates range in size from about 0.5 microns to about 5 microns;

introducing the liquid resin composition into a well bore which penetrates at least a portion of a subterranean formation; and

allowing the resin composition to viscosify to form a flexible material, wherein the material is able to withstand hydrostatic pressure in the well bore once it has viscosified.

14. The method of claim 13 wherein the plurality of filler particulates are present in an amount from about 0.1% to about 70% by weight of the resin composition.

15. The method of claim 13 wherein the liquid hardenable resin component comprises a hardenable resin in an amount in the range of about 5% to about 100% by weight of the liquid hardenable resin component.

16. The method of claim 15 wherein the liquid hardenable resin component further comprises a solvent in an amount in the range of 0.1% to about 30% by weight of the liquid hardenable resin component.

17. The method of claim 13 wherein a hardening agent is present in the liquid hardening agent component in an amount in the range of about 0.1% to about 95% by weight of the liquid hardening agent component.
