Methods for maintaining conductivity of proppant pack

1. A method comprising:

providing first particulates and a liquid composition comprising a tackifying compound and a resin, wherein the ratio of the resin to the tackifying compound is about 1:0.5 to about 1:1;

coating the first particulates with the liquid composition to form coated particulates;

then suspending the coated particulates in a carrier fluid; and

placing the carrier fluid comprising first coated particulates into a portion of a subterranean formation.

2. The method of claim 1 comprising, before the step of placing the carrier fluid:

placing particulates coated with a tackifying compound into substantially the same portion of the subterranean formation as the carrier fluid comprising first coated particulates will be placed.

3. The method of claim 1 wherein the tackifying compound is a material comprising at least one selected from the group consisting of non-aqueous tackifying agents, aqueous tackifying agents, silyl-modified polyamides, and mixtures thereof.

4. The method of claim 1 wherein the tackifying compound further comprises a solvent.

5. The method of claim 1 wherein the tackifying compound is present in the liquid composition in an amount from about 0.1% to about 25% by weight of the particulates.

6. The method of claim 1 wherein the resin is a material comprising at least one selected from the group consisting of two component epoxy-based resins, novolak resins, polyepoxide resins, phenol-aldehyde resins, urea-aldehyde resins, urethane resins, phenolic resins, furan resins, furan/furfuryl alcohol resins, phenolic/latex resins, phenol formaldehyde resins, polyester resins, hybrids of polyester resins, copolymers of polyester resins, polyurethane resins, hybrids of polyurethane resins, copolymers of polyurethane resins, acrylate resins, water-based resins, HT epoxy-based resins, and mixtures thereof.

7. The method of claim 1 wherein the resin further comprises a solvent.

8. The method of claim 1 wherein the resin is present in the liquid composition in an amount from about 0.1% to about 25% by weight of the particulates.

9. A method comprising:

providing particulates, a tackifying compound, and a resin;

coating the particulates with the tackifying compound to form tackifying compound-coated particulates;

coating the tackifying compound-coated particulates with the resin to form twice-coated particulates, wherein the ratio of the resin to the tackifying compound is about 1:0.5 to about 1:1;

then suspending the twice-coated particulates in a carrier fluid; and

placing the carrier fluid into a portion of a subterranean formation.

10. The method of claim 9 comprising, before the step of placing the carrier fluid:

placing particulates coated with a tackifying compound into substantially the same portion of the subterranean formation as the carrier fluid comprising the twice-coated particulates will be placed.

11. The method of claim 9 wherein the tackifying compound is a material comprising at least one selected from the group consisting of non-aqueous tackifying agents, aqueous tackifying agents, silyl-modified polyamides, and mixtures thereof.

12. The method of claim 9 wherein the tackifying compound further comprises a solvent.

13. The method of claim 9 wherein the tackifying compound is present in the liquid composition in an amount from about 0.1% to about 25% by weight of the particulates.

14. The method of claim 9 wherein the resin is a material comprising at least one selected from the group consisting of two component epoxy-based resins, novolak resins, polyepoxide resins, phenol-aldehyde resins, urea-aldehyde resins, urethane resins, phenolic resins, furan resins, furan/furfuryl alcohol resins, phenolic/latex resins, phenol formaldehyde resins, polyester resins, hybrids of polyester resins, copolymers of polyester resins, polyurethane resins, hybrids of polyurethane resins, copolymers of polyurethane resins, acrylate resins, water-based resins, HT epoxy-based resins, and mixtures thereof.

15. The method of claim 9 wherein the resin further comprises a solvent.

16. The method of claim 9 wherein the resin is present in the liquid composition in an amount from about 0.1% to about 25% by weight of the particulates.
