Publication number: 20100298173Abstract: 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: ApplicationFiled: May 13, 2010Publication date: November 25, 2010Applicant: INNOVATIVE CHEMICAL TECHNOLOGIES CANADA LTD.Inventors: Clayton SMITH, Simon John Michael LEVEY, Yonglin (Ginger) REN

Publication number: 20100210484Abstract: A clay stabilizer which is capable of inhibiting swelling in a wide variety of clay types and is also capable of restoring permeability in formations which have previously been damaged by clay swelling. Amine salts of differing molecular weights configurations and ionic strength are combined to provide transport into micropores, mesopores and macropores in the formation and to effect cationic change therein. A poly quaternary amine having a high to very high charge density is added along with lower molecular weight amine salts to substantially permanently exchange cations with the clay in the formation.Type: ApplicationFiled: April 27, 2010Publication date: August 19, 2010Applicant: INNOVATIVE CHEMICAL TECHNOLOGIES CANADA LTD.Inventors: Clayton SMITH, Darin OSWALD, Michael D.

Patent number: 7500522Abstract: Asphaltene control additives are added to base fluids which are introduced directly or indirectly into a hydrocarbon-bearing formation to mitigate asphaltene deposition in the formation which results in improved permeability in the formation and production of hydrocarbons therefrom. The fluids to which the additive is added may be liquid CO2-based, aqueous-based or non-aqueous-based fluids. Further, the fluids are fracturing fluids, drilling fluids and wellbore treatment fluids such as acidizing fluids.Type: GrantFiled: September 21, 2006Date of Patent: March 10, 2009Assignee: Innovative Chemical Technologies Canada Ltd.Inventors: Dan Skibinski, Clayton Smith

Publication number: 20080146466Abstract: 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: ApplicationFiled: December 14, 2007Publication date: June 19, 2008Applicant: INNOVATIVE CHEMICAL TECHNOLOGIES CANADA LTD.Inventors: Clayton SMITH, Simon John Michael LEVEY

Publication number: 20080121564Abstract: 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: ApplicationFiled: November 27, 2007Publication date: May 29, 2008Applicant: INNOVATIVE CHEMICAL TECHNOLOGIES CANADA LTD.Inventors: Clayton Smith, Simon John Michael Levey

Patent number: 7219735Abstract: A packer fluid is provided for use with a wellbore fluid in an annulus or casing bore, having an aqueous portion which contains additives for preventing corrosion, microbiological activity, salt and scale deposition, and an environmentally-acceptable capping fluid which resides at a top of the wellbore to act as freeze protection and as thermal insulation in a the frost penetration layer. The additives in the packer fluid are particularly selected to exist in the aqueous additive fluid and in the wellbore fluid and to be substantially immiscible with the capping fluid and thereby prevent significant migration of the additives into the capping fluid which would compromise its environmental acceptability.Type: GrantFiled: October 30, 2003Date of Patent: May 22, 2007Assignee: Innovative Chemical Technologies Canada Ltd.Inventors: Clayton Smith, Dan Skibinski

Publication number: 20060281636Abstract: An acidizing formulation for use in the stimulation of hydrocarbon production is stable when packaged and stored as a single fluid for periods exceeding one year. The formulation contains a miscibility solvent which substantially prevents any phase separation between the constituents and lack of dispersion of the additives in the fluid.Type: ApplicationFiled: June 9, 2006Publication date: December 14, 2006Applicant: INNOVATIVE CHEMICAL TECHNOLOGIES CANADA LTD.Inventors: Clayton SMITH, Darin OSWALD, Dan SKIBINSKI, Nicole SYLVESTRE
