Abstract

A treatment composition for use in treating production fluids in or from a subterranean formation is provided. The treatment composition can be used for viscosity control in subsea umbilical fluid delivery applications, wherein the treatment composition exhibits desirable viscosity, flash point and/or pour point values.

Claims (16)

1 . A treatment composition for a production fluid in an oil and gas pipeline, the treatment composition comprising:

at least one treatment chemical; and

a solvent comprising ethylene glycol n-butyl ether acetate, wherein the treatment composition is capable of being injected into a subsea umbilical line and delivered to the production fluid from another location.

2 . The treatment composition of claim 1 , wherein the at least one treatment chemical comprises a corrosion inhibitor.

3 . The treatment composition of claim 1 , wherein the production fluid comprises crude oil.

4 . The treatment composition of claim 1 , wherein the production fluid comprises natural gas.

5 . A treatment composition for a production fluid from an oil and gas well, the treatment composition comprising:

at least one treatment chemical; and

a solvent having a flash point of 60° C. or greater and a viscosity of 1.81 cP or lower at 20° C. and 1 bar, wherein the treatment composition is capable of being injected into a subsea umbilical line and delivered to the production fluid from another location.

6 . The treatment composition of claim 5 , wherein the at least one treatment chemical comprises a corrosion inhibitor that is chemically stable in the solvent.

7 .- 15 . (canceled)

16 . The treatment composition of claim 5 , wherein the solvent comprises ethylene glycol n-butyl ether acetate.

17 . The treatment composition of claim 1 , wherein the treatment composition does not comprise any water.

18 . The treatment composition of claim 5 , wherein the treatment composition does not comprise any water.

19 . The treatment composition of claim 5 , wherein the solvent has a pour point of −20° C. or lower.

20 . The treatment composition of claim 5 , wherein the solvent has a freezing point of about −64° C.
