Well servicing fluid
View Patent ↗The present disclosure is directed to a method of servicing a well. The method comprises providing a well servicing fluid. The well servicing fluid is formulated with the following components comprising, at least one friction reducer chosen from polychloroprenes, vinyl acetate polymers, polyalkylene oxides polyalphaolefins; and a nonaqueous carrier fluid. The well servicing fluid is introduced into the well.
1. A method of servicing a well, the method comprising:
providing a well servicing fluid formulated with the following components comprising:
at least one friction reducer chosen from polychloroprenes and vinyl acetate polymers; and
a nonaqueous carrier fluid; and
introducing the well servicing fluid into the well.
2. The method of claim 1 , wherein the method further comprises fracturing a well formation by contacting the well formation with the well servicing fluid.
3. The method of claim 1 , wherein the method further comprises cleaning a tubular positioned within the well using the well servicing fluid.
4. The method of claim 1 , wherein the well servicing fluid comprises about 5% by weight water or less.
5. The method of claim 1 , wherein the well servicing fluid further comprises at least one nonsolvent of the friction reducer.
6. The method of claim 5 , wherein the at least one nonsolvent is chosen from alcohols, glycol ethers, ketones and esters.
7. The method of claim 5 , wherein the at least one nonsolvent comprises a glycol ether and an alkyl alcohol.
8. The method of claim 7 , wherein the glycol ether is propylene glycol ether.
9. The method of claim 1 , wherein the nonaqueous carrier comprises hydrocarbons.
10. The method of claim 1 , wherein the nonaqueous carrier comprises aromatic hydrocarbons and aliphatic hydrocarbons.
11. The method of claim 1 , wherein the nonaqueous carrier is in a concentration of 50% by weight or more based on the total weight of the well servicing fluid.
12. The method of claim 1 , wherein the concentration of friction reducer ranges from about 0.1 gptg to about 10 gptg, based on the total well servicing fluid.
13. The method of claim 1 , wherein the well servicing fluid is formulated to include a surfactant.
14. The method of claim 1 , wherein the well servicing fluid is formulated to include an oil gelling agent.
15. The method of claim 14 , wherein the oil gelling agent is chosen from phosphate esters, aluminum soaps and aluminum fatty acid salts.
16. The method of claim 1 , wherein the well servicing fluid further comprises a proppant.
17. The method of claim 1 , wherein the nonaqueous carrier fluid further comprises carbon dioxide.
18. The method of claim 1 , wherein the nonaqueous carrier fluid further comprises nitrogen.
19. The method of claim 1 , wherein the well servicing fluid is formulated with at least one additional ingredient chosen from non-emulsifiers, viscosifying agents, clay stabilization additives, scale dissolvers, biopolymer degradation additives, fluid loss control additives, breakers and high temperature stabilizers.
20. A method of servicing a well, the method comprising:
providing a well servicing fluid formulated with the following components comprising:
at least one friction reducer chosen from polychloroprenes, vinyl acetate polymers, polyalkylene oxides and polyalphaolefins;
a nonaqueous carrier fluid; and
at least one nonsolvent of the friction reducer; and
introducing the well servicing fluid into the well.
21. The method of claim 20 , wherein the at least one friction reducer comprises a dispersion of particles in the at least one nonsolvent, the particles being chosen from polychloroprenes, vinyl acetate polymers, polyalkylene oxides, and polyalphaolefins.
22. The method of claim 20 , wherein the at least one nonsolvent is chosen from alcohols, glycol ethers, ketones and esters.
23. The method of claim 20 , wherein the at least one nonsolvent comprises a glycol ether and an alkyl alcohol.
24. The method of claim 23 , wherein the glycol ether is propylene glycol ether.
