| Number | Title | Issue Date |
| 7776931 | Low dosage naphthenate inhibitors Low dosage naphthenate inhibitors, such as a surfactant or hydrotrope, delivered into production fluids for contact with mixtures of oil and water, such as in a hydrocarbon producing formation, production equipment, or processing systems. Inhibitor compounds such as... | 08/17/2010 |
| 7776930 | Methods for inhibiting naphthenate salt precipitates and naphthenate-stabilized emulsions Inhibiting naphthenate salts that can form precipitates or emulsions during crude oil production or processing. An effective amount of a naphthenate inhibitor, such as a hydrotrope, is provided into the production fluids for contact with mixtures of oil and water in... | 08/17/2010 |
| 7381689 | Methods for inhibiting hydrate blockage in oil and gas pipelines using amide compounds A method and an amide composition used therein for inhibiting, retarding, mitigating, reducing, controlling and/or delaying formation of hydrocarbon hydrates or agglomerates of hydrates. The method may be applied to prevent or reduce or mitigate plugging of conduits... | 06/03/2008 |
| 7373276 | Quantitative evaluation of emulsion stability based on critical electric field measurements A method for quantitative evaluation of emulsion stability using Critical Electric Field (CEF) determinations over a range of conditions, such as a range of temperatures, demulsifier compositions, or demulsifier concentrations. The method includes determining the CE... | 05/13/2008 |
| 7264653 | Methods for inhibiting hydrate blockage in oil and gas pipelines using simple quaternary ammonium and phosphonium compounds A method and a quaternary ammonium or phosphonium composition used therein for inhibiting retarding, mitigating, reducing, controlling and/or delaying formation of hydrocarbon hydrates or agglomerates of hydrates. The method may be applied to prevent or reduce or mi... | 09/04/2007 |
| 6815208 | Chemical treatment for hydrostatic test A method of treating hydrotest water to inhibits oxygen corrosion, microbiologically influenced corrosion (MIC) and to allow safe discharge of water. The combination treatment plan reduces biocide usage in a high pH brine. The reduced overall chemical usage facilita... | 11/09/2004 |
| 6475431 | Corrosion inhibitors with low environmental toxicity A low toxic, biodegradable, water soluble and dispersant series of corrosion inhibitors are described.
