Patent number: 10392903Abstract: Copolymers containing acryloylmorpholine and vinylimidazole, and optionally vinylcaprolactam and/or n-vinyl pyrrolidone, have shown superior results in hydrate inhibition tests at conditions of 7° C. subcooling dosed at 1 vol % based on the water cut of the system fluids. The copolymer product has also passed high TDS (total dissolved solids) brine compatibility tests and secondary property tests including foaming and hot injection tests which make it useful as a kinetic hydrate inhibitor in gas production systems susceptible to the formation of natural gas hydrates.Type: GrantFiled: July 6, 2018Date of Patent: August 27, 2019Assignee: Baker Hughes, a GE company, LLCInventors: Howard James Spencer, Ravinder Virdee, Michael P.

Publication number: 20170306247Abstract: Hydrogen sulfide (H2S) and/or mercaptan scavengers are chemicals that remove H2S and/or mercaptans from gas, oil and water. Water-based formulations may be made and used employing scavenging compounds having the formulae: wherein each R1, R2, R3, and R4 are the same or different and are selected from the group consisting of hydrogen, an alkyl, an alkenyl, an aryl, an acyl, a halogen, a hydroxyl, a nitro, an alkyl ester, an aryl ester, an alkyl ether, an aryl ether, a hydroxymethyl, an anhydride group, an amino, and a sulfide. In one non-limiting embodiment the compounds (A) and (B) do not contain nitrogen atoms. Water-based formulations, such as those using a protic solvent with the above compounds, work well as H2S scavengers.Type: ApplicationFiled: July 8, 2017Publication date: October 26, 2017Applicant: Baker Hughes, a GE company, LLCInventors: Sunder Ramachandran, Vladimir Jovancicevic, Ying H.

Patent number: 9260669Abstract: The use of neutral aqueous solutions of glyoxal (pH approximately 6 to 8.5) scavenges H2S that is present in natural gas and in oil better than glyoxal alone or base alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over glyoxal used alone. A buffer may be optionally used. In another embodiment, the combination of non-nitrogen-containing surfactants and glyoxal results in a significant increase in the reaction rate and the overall scavenging efficiency, i.e. capacity as compared to glyoxal used alone.Type: GrantFiled: February 29, 2012Date of Patent: February 16, 2016Assignee: BAKER HUGHES INCORPORATEDInventors: Sunder Ramachandran, Vladimir Jovancicevic, Kyle C.

Patent number: 8703655Abstract: A homopolymer of a monomer selected from those having the general formula: wherein: R1 is H or CH3; R2 is H or an alkyl group having from 1 to about 4 carbon atoms; A is a straight or branched chain alkyl group having from 1 to 10 carbon atoms; and R3, R4, and R5 each are independently an alkyl group having from 1 to 6 carbon atoms; or a copolymer of such monomers as acrylate, acrylamide or methacrylamide may be used to disperse metal sulfides prior to their forming scales during the production and transportation of crude oil. Terpolymers of dimethyldiallylammonium salt, 2-hydroxypropyl acrylate; and acrylic acid may also be used for this purpose. The production fluid may also be treated with a compound that promotes the formation of dispersible sulfide scales.Type: GrantFiled: June 9, 2008Date of Patent: April 22, 2014Assignee: Baker Hughes IncorporatedInventors: Marc N.
