Claims
- 1] A method for increasing the thermal stability of a well fluid comprising:
mixing an effective amount of a miscible amine in the well fluid, wherein the well fluid comprises a synthetic polymer.
- 2] The method of claim 1, wherein the miscible amine comprises an amine selected from the group consisting of primary, secondary and tertiary amines, and mixtures thereof.
- 3] The method of claim 1, wherein the miscible amine comprises about 0.2% to about 20% by weight of the well fluid.
- 4] The method of claim 3, wherein the miscible amine comprises about 0.6% to about 12% by weight of the well fluid.
- 5] The method of claim 3, wherein the synthetic polymer comprises about 0.3% to about 5% by weight of the well fluid.
- 6] The method of claim 4, wherein the synthetic polymer comprises about 0.6% to about 2.6% by weight of the well fluid.
- 7] The method of claim 1, wherein the synthetic polymer comprises polyethylene glycol.
- 8] The method of claim 1, wherein the miscible amine comprises triethanol amine.
- 9] A method for increasing the thermal stability of a well fluid comprising:
mixing about 0.2% to about 20% by weight of a miscible amine into the well fluid, wherein the well fluid comprises a synthetic polymer.
- 10] The method of claim 9, wherein the miscible amine comprises an amine selected from the group consisting of primary, secondary and tertiary amines, and mixtures thereof.
- 11] The method of claim 9, wherein the synthetic polymer comprises polyethylene glycol.
- 12] The method of claim 10, wherein the synthetic polymer comprises about 0.3% to about 5% by weight of the well fluid.
- 13] The method of claim 9, wherein the miscible amine comprises triethanol amine.
- 14] A thermally stable well fluid comprising:
a synthetic polymer; and an effective amount of miscible amine.
- 15] The well fluid of claim 14, wherein the miscible amine comprises an amine selected from the group consisting of primary, secondary and tertiary amines, and mixtures thereof.
- 16] The well fluid of claim 14, wherein the synthetic polymer comprises polyethylene glycol.
- 17] The well fluid of claim 14, wherein the miscible amine comprises triethanol amine.
- 18] The well fluid of claim 14, wherein the miscible amine comprises about 0.2% to about 20% by weight of the well fluid.
- 19] The well fluid of claim 18, wherein the miscible amine comprises about 0.6% to about 12% by weight of the well fluid.
- 20] The well fluid of claim 18, wherein the synthetic polymer comprises about 0.3% to about 5% by weight of the well fluid.
- 21] The well fluid of claim 19, wherein the synthetic polymer comprises about 0.6% to about 2.6% by weight of the well fluid.
- 22] A method of treating a well comprising:
injecting a well treating fluid into the well, wherein the well treating fluid comprises a synthetic polymer and an effective amount of a miscible amine.
- 23] The method of claim 22, wherein the miscible amine comprises an amine selected from the group consisting of primary, secondary and tertiary amines and mixtures thereof.
- 24] The method of claim 22, wherein the synthetic polymer comprises polyethylene glycol.
- 25] The method of claim 22, wherein the miscible amine comprises triethanol amine.
- 26] The method of claim 22, wherein the miscible amine comprises about 0.2% to about 20% by weight of the well treating fluid.
- 27] The method of claim 26, wherein the miscible amine comprises about 0.6% to about 12% by weight of the well treating fluid.
- 28] The method of claim 26, wherein the synthetic polymer comprises about 0.3% to about 5% by weight of the well treating fluid.
- 29] The method of claim 27, wherein the synthetic polymer comprises about 0.6% to about 2.6% by weight of the well treating fluid.
