Fluid efficiency and flow back enhancer
The invention provides Formula I compounds, and its compositions, wherein HG, X, L, Y, m, and n are defined in the specification, as fluid efficiency and flow back enhancers for use in a method of treating subterranean formations.
1. A method for treating a subterranean formation, comprising:
placing a fluid composition into the subterranean formation, the fluid composition comprises a compound selected from the group consisting of:
and
combinations thereof.
2. The method of claim 1 , wherein the fluid composition comprises:
3. The method of claim 1 , wherein the fluid composition comprises:
4. The method of claim 1 , wherein contacting the subterranean formation comprises placing the fluid composition in at least one of a fracture and flowpath in the subterranean formation.
5. The method of claim 4 , wherein the fracture is present in the subterranean formation at the time when the fluid composition is contacted with the subterranean formation.
6. The method of claim 5 , wherein the method further comprises forming the fracture or flowpath.
7. The method of claim 1 , further comprising fracturing at least a portion of the subterranean formation to form a fracture in the subterranean formation.
8. The method of claim 7 , further comprising depositing a proppant into the fracture, and wherein the fluid composition comprises the proppant.
9. The method of claim 8 , wherein the proppant comprises a resin.
10. The method of claim 1 , wherein the compound comprises about 0.1 wt % to about 10 wt % of the fluid composition.
11. The method of claim 1 , further comprising combining the fluid composition with a fracturing fluid.
12. The method of claim 1 , wherein contacting the subterranean formation occurs in a formation matrix located in the subterranean formation.
13. The method of claim 1 , wherein subsequent to placing the fluid composition into the subterranean formation, the method further comprises:
contacting the fluid composition with another fluid having a pH sufficient to cleave a bond in a linker group of the compound; and
cleaving the bond.
14. The method of claim 13 , wherein the pH of the fluid is less than 6.
15. The method of claim 14 , wherein the pH of the fluid is less than 2.
16. The method of claim 1 , wherein placing the composition in the subterranean formation comprises pumping the composition through a drill string disposed in a wellbore within the subterranean formation, through a drill bit at a downhole end of the drill string, and back above-surface through an annulus.
17. The method of claim 16 , further comprising processing the composition exiting the annulus with a fluid processing unit to generate a cleaned composition and recirculating the cleaned composition through the wellbore.
18. A method for treating a subterranean formation, comprising:
placing a fluid composition into the subterranean formation, the fluid composition comprises a proppant and a compound selected from the group consisting of:
and
combinations thereof; and
fracturing at least a portion of the subterranean formation to form a fracture or flowpath in the subterranean formation.
19. A composition, comprising:
a carrier fluid; and
a fluid composition comprising a compound selected from the group consisting of:
and
combinations thereof.
