Publication number: 20220403250Abstract: A method of treating contaminated materials such as oil and gas production waste sludges to recover crude oil hydrocarbons. The method includes the inversion of water-in-oil emulsions, and subsequent separation steps. These may involve the separation and removal of asphaltenes, petroleum waxes and/or solid particles from the crude oil hydrocarbons. The treatment method uses the physical phenomena of hydrodynamic cavitation and hydraulic shock, which produce different effects upon a mixture of water and the contaminated material being treated. These are deployed either as single or combined stage(s) of treatment or as a repeated series of single/combined treatment stages, with or without additional processing operations between each single/combined treatment stage. The method may be implemented with suitable plant including hydrodynamic cavitation units (103, 106) and hydraulic shock units (104, 107), followed by separators (105, 108).Type: ApplicationFiled: November 12, 2020Publication date: December 22, 2022Inventors: Mark BATT-RAWDEN, Michael LEVEY

Publication number: 20180037804Abstract: The implementations described herein relate to imidazoline quaternary ammonium based compositions, processes for the preparation thereof and to the use of imidazoline quaternary ammonium based compositions as anti-agglomerants. In some implementations, the anti-agglomerant compositions described herein are able to handle greater than 10° C. subcooling in a sour system up to 40,000 ppm H2S and also without the need for a hydrocarbon phase. It is believed that some of the anti-agglomerants described herein can function without a hydrocarbon phase in sour conditions.Type: ApplicationFiled: October 3, 2017Publication date: February 8, 2018Inventors: Simon John Michael Levey, Robert Fowles, Duane S. Treybig

Patent number: 9249350Abstract: Anti-accretion additives utilize silicone chemistry to prevent bituminous and heavy oil materials from sticking to metals surfaces such as drill bits, drillstring, casing and the like. Organopolysiloxanes and/or copolymers thereof are added directly to an aqueous drilling fluid or are first diluted in a solvent for adding to the drilling fluid. Further, an alkyl polyalkylene oxide may also be added. If a silicone oil is used as the solvent, the anti-accretion additive has the increased functionality of minimizing the amount of bituminous or heavy oil material which is retained in the drilling fluid when returned to surface and permits removal of the bituminous or heavy oil materials with the solids using conventional solids control equipment.Type: GrantFiled: May 13, 2010Date of Patent: February 2, 2016Assignee: LUBRIZOL OILFIELD SOLUTIONS, INC.Inventors: Clayton Smith, Simon John Michael Levey, Yonglin (Ginger) Ren

Patent number: 8709983Abstract: A substantially liquid gellant formed as one or more reaction products of a metal carboxylate or metal carboxylate amine salt, one or more organic acids, an ester which drives the reaction so that the reaction products are asymmetrical in structure, and a rheology modifier which preferentially interacts between the reaction products for prevent solidifying of the gellant reaction products until such time as the gellant is mixed with the fracturing fluid containing an activator after which the reaction products preferentially interact with the activator to gel the fracturing fluid. The resulting gellant is capable of gelling a hydrocarbon base fluid in less than about 30 seconds.Type: GrantFiled: February 4, 2011Date of Patent: April 29, 2014Assignee: Weatherford Canada PartnershipInventors: Clayton Smith, Simon John Michael Levey

Patent number: 7754661Abstract: A method of recovering hydrocarbon or synthetic base oils from used oil-based drilling mud utilizes acid to deactivate emulsifiers in the drilling mud for altering the emulsion stability and permitting removal of the solids contained in the drilling mud using conventional separation such as centrifugation. A surfactant is typically added to prevent water-wetting as a result of the addition of the acid. The recovered base oil contains substantially all of the deactivated emulsifiers, which can be reactivated through the addition of lime, allowing new drilling fluids to be prepared without the need to add significant amounts of emulsifier to the recycled base oil.Type: GrantFiled: November 27, 2007Date of Patent: July 13, 2010Inventors: Clayton Smith, Simon John Michael Levey
