Claims
- 1. A well fluid comprising:
a glycol compound; and an organic liquid, wherein the glycol compound and the organic liquid are present in amounts selected to achieve a predetermined density suitable for annular pressure control.
- 2. The well fluid of claim 1, further comprising water.
- 3. The well fluid of claim 1, further comprising a salt solution.
- 4. The well fluid of claim 1, wherein the well fluid is substantially water-free.
- 5. The well fluid of claim 1, further comprising a polymer, wherein the polymer, the glycol compound, and the organic liquid are present in amounts selected to achieve a predetermined heat capacity.
- 6. The well fluid of claim 1, further comprising a polymer, wherein the polymer, the glycol compound, and the organic liquid are present in amounts selected to achieve a predetermined thermal conductivity.
- 7. The well fluid of claim 1, further comprising a polymer, wherein the polymer, the glycol compound, and the organic liquid are present in amounts selected to achieve a predetermined viscosity.
- 8. The well fluid of claim 3, wherein the salt solution comprises at least one selected from the group consisting of halide brines, formate brines, and acetate brines.
- 9. The well fluid of claim 8, wherein the salt solution comprises calcium bromide.
- 10. The well fluid of claim 1, wherein the glycol compound comprises at least one selected from the group consisting of ethylene glycol, propylene glycol, and monoethylene glycol.
- 11. The well fluid of claim 1, wherein the glycol compound comprises 20% to 50% of a total weight percentage of the well fluid.
- 12. The well fluid of claim 11, wherein the glycol compound comprises monoethylene glycol.
- 13. The well fluid of claim 1, wherein the organic liquid comprises 20% to 50% of the total weight percentage of the well fluid.
- 14. The well fluid of claim 12, wherein the organic liquid comprises methanol.
- 15. The well fluid of claim 1, wherein the predetermined density comprises 5 ppg to 9 ppg.
- 16. A method of treating a well comprising:
injecting a well-treating fluid into the well, wherein the well-treating fluid comprises a glycol compound, and an organic liquid, the glycol compound and the organic liquid present in amounts selected to achieve a predetermined density suitable for annular pressure control.
- 17. A well fluid comprising:
a glycol compound; and a quaternary amine salt, wherein the glycol compound and the quaternary amine salt are present in amounts selected to achieve a predetermined density suitable for annular pressure control.
- 18. The well fluid of claim 17, further comprising an organic liquid.
- 19. The well fluid of claim 17, wherein the glycol compound and the quaternary amine salt are selected such that a density of the well fluid decreases when the quaternary amine is added to the glycol compound.
- 20. The well fluid of claim 17, wherein the glycol compound comprises at least one selected from the group consisting of ethylene glycol, propylene glycol, and monoethylene glycol.
