COMPOSITIONS AND METHODS FOR RE-FRACTURING WELLS

1 . A method of extracting oil and/or gas from a previously fractured subterranean stratum comprising proppants, the method comprising:

injecting a light weight proppant into the previously fractured subterranean stratum; and

extracting the oil and/or gas from the previously fractured subterranean stratum.

2 . The method of claim 1 , wherein the light weight proppant is injected with slickwater.

3 . The method of claim 1 , wherein the light weight proppant is a coated particulate comprising a particulate core with a compatibilizing agent and a hydrophobic polymer coating the particulate core, wherein a portion of the hydrophobic polymer is exposed to provide an exposed hydrophobic surface of the coated particulate.

4 . The method of claim 3 , wherein the compatibilizing agent binds the hydrophobic polymer to the particulate.

5 . The method of claim 3 , wherein the compatibilizing agent encapsulates the particulate core and a first surface of the hydrophobic polymer binds to the compatibilizing agent and a second surface of the hydrophobic polymer is exposed to provide the exposed hydrophobic surface of the coated particulate.

6 . The method of claim 3 , wherein the coated particulate has enhanced particulate transport as compared to a particulate without the exposed hydrophobic surface.

7 . The method of claim 3 , wherein the compatibilizing agent is a alkoxysilane.

8 . The method of claim 7 , wherein the alkoxysilane is a methoxysilane, ethoxysilane, butoxysilane, or octoxysilane.

9 . The method of claim 3 , wherein the compatibilizing agent is a surfactant.

10 . The method of claim 9 , wherein the surfactant is a hydroxysultaine.

11 . The method of claim 10 , wherein the hydroxysultaine is cocamidopropyl hydroxysultaine.

12 . The method of claim 3 , wherein the compatibilizing agent is an alkoxylated alcohol.

13 . The method of claim 3 , wherein the compatibilizing agent is an acrylate polymer.

14 . The method of claim 3 , wherein the hydrophobic polymer is an amorphous polyalphaolefin.

15 . The method of claim 1 , wherein the hydrophobic polymer is a non-siloxane hydrophobic polymer.

16 . (canceled)

17 . The method of claim 1 , wherein the light weight proppant is substantially free of a hydrogel.

18 - 25 . (canceled)

26 . The method of claim 1 , wherein the light weight proppant is substantially free of a frother.

27 . The method of claim 1 , wherein the light weight proppant has a sand particle core.

28 - 30 . (canceled)

31 . The method of claim 1 , wherein the method increases the fracture height and half-length and/or creates uniform vertical and horizontal proppant distribution as compared to the previously fractured subterranean stratum.

32 . The method of claim 1 , wherein the light weight proppants are injected or treated with a gas.

33 - 37 . (canceled)
