| 20080261853 | Surface Active Polymers as Detergents - Provided herein are compositions useful as detergents in cleaning a wide variety of substrates, including hard surfaces and laundry. The compositions contain a water-soluble polymer, which is a co-polymer between a polymerizable amide and a second, ethylenically-unsaturated monomer. The polymerizable amide itself is prepared from an amine-capped, alkoxylated alcohol by reaction with maleic acid anhydride. Compositions according to the invention show enhanced cleaning performance and beneficial anti-redeposition properties. | 10-23-2008 |
| 20090131283 | IMIDAZOLINE-BASED HETEROCYCLIC FOAMERS FOR DOWNHOLE INJECTION - Disclosed are imidazoline-based foamers and corrosion inhibitors for treatment of oil and gas wells for enhanced production. The invention also includes methods of foaming a fluid by introducing the disclosed foamers to oil and gas wells. | 05-21-2009 |
| 20100113309 | METHOD OF REDUCING THE VISCOSITY OF HYDROCARBON FLUIDS - This invention relates to methods for reducing the viscosity of hydrocarbon liquids encountered in petroleum operations. The method includes forming a low viscosity emulsion by contacting hydrocarbon liquids with an effective amount of a water-soluble polymer having pendant methyl ether groups. | 05-06-2010 |
| 20100227950 | COMB-LIKE POLYETHERALKANOLAMINES IN INKS AND COATINGS - Provided herein are compositions useful as ink or coatings which contain novel dispersants that are capable of dispersing pigments which are traditionally difficult to disperse while maintaining acceptable levels of viscosity. Use of dispersants as taught herein enables the preparation of a wide variety of inks and coatings having high pigment loading and existing within a conventionally-useful viscosity range. | 09-09-2010 |
| 20110009556 | METHOD OF REDUCING THE VISCOSITY OF HYDROCARBON FLUIDS - A method for reducing the viscosity of a hydrocarbon fluid encountered in petroleum operations is disclosed. The method includes contacting the hydrocarbon fluid with an effective amount of a composition comprising at least one polymer having at least 25 mole percent cationic monomers. | 01-13-2011 |
| 20110071059 | FOAMERS FOR DOWNHOLE INJECTION - The present invention relates to a method for introducing a foaming composition including an imidazoline-based compound to a fluid. The foaming composition comprises at least one quaternized compound having an imidazoline moiety. An example of the quaternized compound is a quaternized imidazoline. | 03-24-2011 |
| 20110071060 | FOAMERS FOR DOWNHOLE INJECTION - This invention relates generally to novel foamer compositions for treatment of oil and gas wells to enhance production. The invention provides a method of foaming a fluid. The method includes introducing into the fluid a foam-forming amount of a composition comprising at least one long chain fatty acid and at least one organic solvent. An example of the long chain fatty acid is tall oil fatty acid and an example of the organic solvent is ethyleneglycol monobutyl ether. | 03-24-2011 |
| 20110092393 | METHOD OF REDUCING THE VISCOSITY OF HYDROCARBONS - Methods of treating hydrocarbon fluids to reduce the apparent viscosity of hydrocarbon fluids encountered in petroleum operations and reducing deposits within a well annulus or a pipeline are disclosed. The method comprises contacting such fluids with a hydrophobically modified polysaccharide to create water external emulsions. The disclosed hydrophobically modified polysaccharides have been demonstrated to reduce interfacial tension to below 65 mN/m and thereby improve the transportability of inherently viscous hydrocarbon fluids, such as heavy crude oils. | 04-21-2011 |
