Abstract
Official abstract text for this publication.
A method of preventing or mitigating the formation of metal sulfide scale in a fluid is provided. The fluid can be treated with an additive comprising thiamine. The fluid can be a production fluid from an oil and gas well. The production fluid can include crude oil. The fluid can include an aqueous fluid. The aqueous fluid can further include crude oil. The metal sulfide scale can include iron sulfide scale and/or zinc sulfide scale.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of preventing or mitigating the formation of metal sulfide scale in a fluid, the method comprising treating the fluid with an additive comprising thiamine. 2 . The method of claim 1 , wherein the fluid is a production fluid from an oil and gas well. 3 . The method of claim 2 , wherein the production fluid comprises crude oil. 4 . The method of claim 1 , wherein the fluid comprises an aqueous fluid. 5 . The method of claim 4 , wherein the aqueous fluid further comprises crude oil. 6 . The method of claim 1 , wherein the metal sulfide scale comprises iron sulfide scale. The method of claim 1 , wherein the metal sulfide scale comprises zinc sulfide scale. 8 . A method of preventing or mitigating the formation of metal sulfide scale in downstream equipment containing production fluid from an oil and gas well, the method comprising treating the production fluid with an additive comprising thiamine. 9 . The method of claim 8 , wherein the production fluid comprises crude oil. 10 . The method of claim 8 , wherein the metal sulfide scale comprises iron sulfide scale. 11 . The method of claim 8 , wherein the metal sulfide scale comprises zinc sulfide scale. 12 . The method of claim 8 , wherein the downstream equipment is selected from the group consisting of pipes, pipelines, separators, dehydrators, strainers, centrifuged cyclones, and electrostatic precipitators. 13 . A method of reducing the amount of metal sulfide scale in a fluid, the method comprising treating the fluid with an additive comprising thiamine. 14 . The method of claim 13 , wherein the fluid comprises a production fluid from an oil and gas well. 15 . The method of claim 13 , wherein the production fluid comprises crude oil. 16 . The method of claim 13 , wherein the fluid comprises an aqueous fluid. 17 . The method of claim 16 , wherein the aqueous fluid further comprises crude oil. 18 . The method of claim 13 , wherein the metal sulfide scale comprises iron sulfide scale. 19 . The method of claim 13 , wherein the metal sulfide scale comprises zinc sulfide scale. 20 . A method of reducing the amount of metal sulfide scale in downstream equipment containing production fluid from an oil and gas well, the method comprising treating the production fluid with an additive comprising thiamine. 21 . The method of claim 20 , wherein the production fluid comprises crude oil. 22 . The method of claim 20 , wherein the metal sulfide scale comprises iron sulfide scale. 23 . The method of claim 20 , wherein the metal sulfide scale comprises zinc sulfide scale. 24 . The method of claim 20 , wherein the downstream equipment is selected from the group consisting of pipes, pipelines, separators, dehydrators, strainers, centrifuged cyclones, and electrostatic precipitators.
