Publication number: 20230295486Abstract: A method for inhibiting corrosion of metal surfaces, such as carbon steel tubing, that are in contact with a fluid, such as brine in an oil and gas production fluid containing acid gases (e.g., CO2 and H2S) is accomplished by introducing a corrosion-inhibiting blend of two components into the fluid, where blend is glycolipids and quaternized amines, glycolipids and phosphate-containing compounds, quaternized amines and imidazoline-like compounds, quaternized amines and phosphate-containing compounds, or combinations of these blends. Each of the two components of the blends are present in an amount effective to synergistically inhibiting the corrosion of the metal surface when used together.Type: ApplicationFiled: March 17, 2022Publication date: September 21, 2023Applicant: Baker Hughes Oilfield Operations LLCInventors: Carlos M.

Patent number: 9463989Abstract: The use of a dialdehyde (e.g. glyoxal) and a nitrogen-containing scavenger (e.g. a triazine) when injected separately in media containing hydrogen sulfide (H2S) and/or mercaptans to scavenge H2S and/or mercaptans therefrom gives a synergistically better reaction rate and overall scavenging efficiency, i.e. capacity, over the use of the dialdehyde or the nitrogen-containing scavenger used alone, but in the same total amount of the dialdehyde and nitrogen-containing scavenger.

Publication number: 20110040126Abstract: Corrosion of both ferrous and non-ferrous metals, induced by a variety of corrosive aqueous-based environments, may be inhibited or controlled through use of corrosion inhibiting compositions comprising at least one member of certain formula-specified categories of mercaptan-based compounds. Where the compounds are appropriately selected, and particularly at low inhibitor concentrations, the compositions may inhibit corrosion to a degree that is comparable to or significantly greater than the inhibition provided by an equal amount of certain other corrosion inhibitor compounds. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: ApplicationFiled: October 12, 2010Publication date: February 17, 2011Applicant: BAKER HUGHES INCORPORATEDInventors: Michael D.

Patent number: 7713405Abstract: An electrochemical noise method, apparatus and system may be used to estimate and/or calculate parameters of interest related to corrosion rates of an electrically conductive article. The apparatus involves a working electrode (having substantially the same composition of the electrically conductive article), a reference electrode, and a counter electrode in an environment of interest. The working electrode is placed under potentiostatic control. A current transient between the working electrode and the counter electrode is measured. The working electrode is switched to open potential. A potential transient is measured over the duration of a localized corrosion event. The localized corrosion may then be calculated based on the measured potential transient and the current transient.Type: GrantFiled: May 6, 2008Date of Patent: May 11, 2010Assignee: Baker Hughes IncorporatedInventors: Vladimir Jovancicevic, Carlos M.
