|20130324446||EMULSION BREAKERS INCLUDING POLYESTER FUNCTIONALITIES - An emulsion breaker composition, a method of making the emulsion breaker, and method of breaking an emulsion are disclosed. In one method, an emulsion is contacted with an effective amount of an emulsion breaker composition. The emulsion breaker is a linear or branched polymer having at least one branch, wherein each branch has a first polymer block having a backbone including a plurality of ester groups and a second polymer block including an alkoxylate, and wherein at least two of the ester groups are connected by a —CR1R2 group. The emulsion breakers are preferably formed by reacting a polyol with a cyclic ester monomer in the presence of a first catalyst to form an intermediate polymer having a plurality of branches, wherein each branch has a backbone including a plurality of ester groups, and then reacting the intermediate polymer with at least one alkylene oxide species in the presence of a second catalyst to form an alkoxylate block on each branch.||12-05-2013|
|20120283147||LOW DOSAGE POLYMERIC NAPHTHENATE INHIBITORS - Polymeric naphthenate inhibitors are delivered into production fluids to contact mixtures of oil and water, such as in a hydrocarbon producing formation, production equipment, or processing systems. These polymeric naphthenate inhibitors exhibit surface-active properties causing the inhibitors to self-associate at oil-water interfaces and inhibit interactions between organic acids in the oil and cations or cation complexes in water. The large surface area makes these polymers persistent and effective at low concentrations. These compounds also inhibit aggregation of organic acid carboxylate salts that form when pH and pressure conditions are amenable to organic acid ionization. Preferred inhibitors do not form emulsions due to the formation of unstable mixed interface structures that result in coalescence of dispersed droplets. Naphthenate inhibitor dosages less than 100 ppm can effectively inhibit naphthenate salts or other organic acid salts that can form precipitates or emulsions during crude oil production or processing.||11-08-2012|
|20120212729||THERMAL PHASE SEPARATION SIMULATOR - A thermal phase separation simulator and method for testing chemicals is disclosed. The simulator comprises a circular block heater carousel mounted for rotation on a stage. The carousel includes a circular array of test wells for receiving a plurality of test bottles, a plurality of heating elements and thermocouples disposed between the wells. Each well has an illumination port and a vertical slit to the outside to allow visual observation or imaging of a vertical swatch of the bottle. An illumination source aligns with the illumination port of each well in response to rotation of the carousel. The method includes adding a mixed phase fluid to a plurality of bottles, adding a chemical agent to each bottle, and simulating a thermal phase separation. Images of the fluid in each bottle are captured and analyzed to determine the performance of the one or more chemical agents.||08-23-2012|
|20120088700||Inhibiting Carbon Dioxide Induced Deposition - An asphaltene and resin precipitation inhibiting solution formed of an asphaltene and resin precipitation inhibiting compound and a solvent miscible in a carbon dioxide liquid or supercritical fluid. The inhibiting compound includes a head region with an affinity for asphaltene and resin components of a hydrocarbon mixture that is greater than its affinity for water, carbon dioxide, and aliphatic components of the hydrocarbon mixture. The head region includes one or more unsaturated hydrocarbon groups or one or more nonionic dipolar groups. The inhibiting compound also includes a tail region with an affinity for carbon dioxide that is greater than its affinity for substantially all components of the hydrocarbon mixture and water. The tail region includes one or more nonionic quadrupolar groups. An effective amount of solution is added to a hydrocarbon mixture in an underground reservoir when employing a carbon dioxide fluid to flush the hydrocarbon mixture from the reservoir.||04-12-2012|
|20110302827||Inhibiting Stress Corrosion Cracking of Metal Exposed to Moderate to High Concentrations of Ethanol - An effective stress corrosion cracking (SCC) inhibiting amount of a corrosion inhibitor is added into a blend of fuel and ethanol that contacts a metal, wherein the corrosion inhibitor is an organic acid selected from citric acid, ascorbic acid, succinic acid, pyruvic acid, maleic acid, oxaloacetic acid, oxalosuccinic acid, ketoglutaric acid, isocitric acid, malic acid, aconitic acid, fumaric acid, isomers of these organic acids, and a combination thereof. For example, the corrosion inhibitors inhibit stress corrosion cracking of pipeline grade metal pipe at ethanol concentrations greater than fifteen percent. In one embodiment, the corrosion inhibitor is added into a blend of fuel and ethanol flowing through a pipeline at a plurality of injection points spaced apart along the length of the pipeline. In one option, the corrosion inhibitor is ammoniated to form the ammonium salt of the organic acid. In another option, the foregoing corrosion inhibitors are used in combination with one or more conventional corrosion inhibitors in an amount that is effective to inhibit general corrosion.||12-15-2011|
|20100324166||USING DISPERSION POLYMERS WITH NONIONIC CHARACTERISTICS AND FORMULATIONS TO REDUCE FRICTION - This invention discloses, compositions of aqueous fluids comprising one or more dispersion polymer(s), wherein the dispersion polymer comprises 96 to 100 mole percent of one or more nonionic monomer units and 0 to 4 mole percent of one or more cationic or anionic monomer units; and has a molecular weight of at least 100,000. The invention also discloses the method(s) of using one or more such dispersion polymer(s), comprising adding to or mixing with the aqueous fluid a friction-reducing amount of the polymer(s), before, during or after a turbulent flow is induced. Nonionic dispersion polymers consistently render substantially greater extents of friction reduction than their ionic counterparts. A dispersion polymer (formed by dispersion polymerization) provides up to four times as much friction reduction as the same polymer in solution when used at the same dosage. Moreover, unlike ionic dispersion polymers, nonionic dispersion polymers are intrinsically compatible with charged oilfield species such as multi-valence brine(s), quaternary amine-based corrosion inhibitors and biocides.||12-23-2010|
|20100163494||PREPARATION OF ENVIRONMENTALLY ACCEPTABLE SCALE INHIBITORS - Alkyl phosphonates prepared from amino acids suitable for use in inhibiting scale. The phosphonates are obtained as reaction mixtures where the level of alkyl phosphonation is deliberately controlled to provide only partial alkyl phosphonation of the amino acid. The resulting alkyl phosphonates exhibit improved environmental properties compared to the fully substituted species, while still exhibiting acceptable efficacy in the control of scale. The compositions possess advantages over existing phosphonates in that they exhibit higher biodegradation by method OECD 306. They also offer lower toxicity to marine life compared to the fully substituted species and are not expected to bioaccumulate.||07-01-2010|
|20090235730||METHOD FOR CLEANING AN OIL FIELD CAPILLARY TUBE - A method and apparatus for removing deposits formed within a capillary tube that has been used to deliver treatment chemicals into a well. The method includes pumping a cleaning solution through the capillary tube coil, preferably after the capillary tube has been removed from the well and formed as a coil. The cleaning solution comprises at least 20 weight percent of a surfactant or dispersant, at least 5 weight percent of a coupling agent, and at least 10 weight percent solvent. A preferred surfactant or dispersant is selected from the group consisting of an alkyl-aryl sulphonate and a phosphate ester.
