Zhengwei Liu - Sugar Land TX, US

Assignee:

Baker Hughes Oilfield Operations LLC - Houston TX

International Classification:

C23F 11/16
C23F 11/14

Abstract:

A method of preventing or mitigating corrosion on a metallic surface exposed to a supercritical fluid is disclosed. The method includes adding a corrosion inhibitor composition to a supercritical fluid comprising a supercritical carbon dioxide; and contacting the supercritical fluid with a metallic surface, wherein the corrosion inhibitor composition comprises a corrosion inhibitor that has a solubility of greater than 5,000 ppm in the supercritical fluid at 48.9 C. and 2,200 psi.

F17D 3/12
F17D 5/00
E21B 37/06

Abstract:

A corrosion inhibitor additive is circulated in a system with a corrosion environment to inhibit metal corrosion. The corrosion inhibitor additive includes a first component and a second component. The second component includes without limitation, imidazolines, amides, quaternary amines, carboxylic acid reaction products, organophosphates, phenathradine derivatives, heterocyclic molecules containing one or both of nitrogen and sulfur, and combinations thereof. The first component may have one of the following formulas:wherein x is oxygen or hydrogenated nitrogen or quaternized nitrogen; R, R, Rand Rare independently hydrogen, methyl or an alkyl group; p, q and n are independently integers from 1 to 100; andwhere z is an integer ranging from 1 to 100; and where a lower amount of the corrosion inhibitor additive is used to achieve the same or better results in inhibiting the corrosion of the metal surface as compared to an otherwise identical method for inhibiting corrosion absent the corrosion inhibitor additive.

Abstract:

A composition for inhibiting corrosion of a metal is provided. The corrosion inhibitor composition comprises 5-amino-2-mercaptobenzimidazole. The corrosion inhibitor composition can also comprise a 2-mercaptobenzimidazole derivative selected from the group consisting of 2-mercapto-5-methylbenzimidazole, 5-Ethoxy-2-mercaptobenzimidazole, 5-(difluoromethoxy)-2-mercapto-1H-benzimidazole 1-Methyl-1H-benzimidazole-2-thiol and 2-mercapto-5-nitrobenzimidazole. The corrosion inhibitor composition outperforms many other sulfur-containing corrosion inhibitors in kettle testing.

Appl. No.:

15/354578

Inventors:

- Houston TX, US
Tracey Jackson - Sugar Land TX, US

Assignee:

BAKER HUGHES INCORPORATED - Houston TX

International Classification:

C23F 11/18
C09D 5/08
C09D 1/00

Abstract:

Corrosion to a metal surface in contact with corrosion forming components within an aqueous-based fluid system may be decreased, prevented, and/or inhibited by contacting the metal surface(s) with apatite forming components and forming at least one apatite species on the surface with the apatite forming components. The apatite forming components may be or include phosphates, organophosphates and combinations thereof. In a non-limiting embodiment, the apatite forming components may further include fluorides, chlorides, calcium, and combinations thereof.

International Classification:

C09K 8/528
C02F 5/14
C02F 5/12

Abstract:

Two intermediates that have known separate efficacy for preventing scales such as calcium carbonate, magnesium carbonate and barite (barium sulfate) were discovered to have a synergistic effect for preventing or inhibiting silicate scaling when used together. Each of these intermediates is ineffective at preventing silicate scaling when used alone; however, when used in combination, they have a synergistic benefit. In one non-limiting embodiment the components include a polyamine phosphonate and a lysine tetra(alkylene)phosphonate.

Abstract:

A corrosion inhibitor additive may be circulated in a subterranean formation in an effective amount to decrease metal corrosion in a high temperature environment. The corrosion inhibitor additive may include at least one first inhibitor and at least one second inhibitor. The second inhibitor(s) may include imidazolines, quaternary amines, phosphate esters, and combinations thereof. The first inhibitor(s) may have one of the following formulas:wherein x is oxygen or hydrogenated nitrogen or quaternized nitrogen; R, R, Rand Rare independently hydrogen, methyl or an alkyl group; p, q and n are integers from 1 to 100; andwhere z is an integer ranging from 1 to 100.
