Patent number: 9340725Abstract: Preparing a demulsifier, an oil soluble imidazoline corrosion inhibitor, an alkylphenolic resin, an alkylphenolic resin oxyalkylate, a paraffin inhibitor, a defoamer, an oil soluble scavenger, an oil soluble cleaner, a wetting agent, a surfactant, a foamer, and combinations thereof, in a non-limiting embodiment, in the absence of a BTEX solvent would be more beneficial to the environment than the same products prepared with BTEX solvent(s). The method may include adding an organic solvent to a mixture to form the aforementioned material(s). The organic solvent may be or include propylene glycol methyl ether acetate (PGMEA currently marketed as DOWANOL PMA™), dipropylene glycol methyl ether acetate (currently marketed as DOWANOL DPMA™), diisobutyl ketone (DIBK), methyl isobutylketone (MIBK), and mixtures thereof.Type: GrantFiled: August 19, 2011Date of Patent: May 17, 2016Assignee: Baker Hughes IncorporatedInventor: David J.

Patent number: 8765020Abstract: Mitigating or preventing corrosion of metal may be achieved in systems that are alkaline, such as carbon dioxide capture systems. The method may include adding an additive to a system wherein the system is at an alkaline pH; the system has both O2 and CO2 present; or the system is at an alkaline pH and has both O2 and CO2 present. The additive may be selected from the group consisting of: quaternary aromatic amines; quaternary alkyl substituted aromatic amines; and combinations thereof. The corrosion inhibiting properties of the additives may be increased by use of synergistic combinants. The abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: GrantFiled: May 17, 2010Date of Patent: July 1, 2014Assignee: Baker Hughes IncorporatedInventors: Ksenija Babić-Samard{hacek over (z)}ija, Lawrence N.

Patent number: 7838468Abstract: A clayish subterranean formation, such as may be encountered in rock surrounding a well bore during hydrocarbon recovery operations may be stabilized with relatively high molecular weight acid ammonium salts of an imide of polymaleic anhydride. The salts may be unneutralized or partially neutralized. The invention is particularly relevant to hydraulic fracturing fluids used in enhanced oil recovery. The compositions herein are made in the presence of a reactive solvent, such as a polyalkylene glycol, e.g. polyethylene glycol. The compositions of this invention are more environmentally friendly than some current technology.Type: GrantFiled: January 4, 2008Date of Patent: November 23, 2010Assignee: Baker Hughes IncorporatedInventors: David J. Poelker, JoAnn McMahon, John A. Schield

Patent number: 6558619Abstract: A corrosion inhibitor comprising a quantity of a phosphorylated oxyalkylated polyol at a pH of 5.0 or higher which produces a first level of corrosion loss in an oxygenated corrosive system under given conditions, and an amount of a passivating agent effective to decrease the corrosion loss under said given conditions to a second level which is less than the first level. The passivating agent minimizes the impact of the corrosion inhibitor on the rheology of drilling system fluids.Type: GrantFiled: August 9, 1999Date of Patent: May 6, 2003Assignee: Baker Hughes IncorporatedInventors: Michael L.
