  • Publication number: 20140166288
    Abstract: A method of performing a squeeze treatment comprises pumping a treatment fluid under pressure through a wellbore into a subterranean formation, wherein the treatment fluid includes a hydrogen sulfide scavenging compound that adsorbs onto the subterranean formation in a region around the wellbore. Production fluids are then allowed to flow from the subterranean formation into the wellbore, wherein the production fluids contact the adsorbed hydrogen sulfide scavenging compound as the production fluids flow through the region around the wellbore, and wherein the production fluids contain hydrogen sulfide that reacts with the hydrogen sulfide scavenging compound to reduce an amount of hydrogen sulfide in the production fluids before the production fluids flow into the wellbore.

  • Publication number: 20140166282
    Abstract: Functionalized alpha-hydroxy alkyl ethers have been found to perform as non (or anti-) scaling hydrogen sulfide scavengers. A method of scavenging hydrogen sulfide includes contacting a fluid containing hydrogen sulfide with a treatment fluid including a functionalized alpha-hydroxy alkyl ether. Accordingly, the alpha-hydroxy alkyl ether reacts with the hydrogen sulfide to reduce the amount of hydrogen sulfide in the fluid. The functionalized alpha-hydroxy alkyl ether is functionalized with a phosphate group, phosphonate group, sulfate group, or sulfonate group. A broad range of alpha-hydroxy alkyl ethers are disclosed.

  • Patent number: 7776930
    Abstract: 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 the formation, the production equipment, or processing systems. It is believed that the naphthenate inhibitors, such as monophosphate ester or diphosphate ester, exhibit surface-active properties that cause the inhibitors to align and concentrate in a layer at the oil-water interface and thereby prevent interactions between organic acids in the oil phase with cations or cation complexes in the water. It is believed that the physical positioning and geometry of the naphthenate inhibitor blocks the growth of naphthenate salt crystals. However, it is preferred that the naphthenate inhibitors also avoid the formation of oil-in-water and water-in-oil emulsions.

  • Patent number: 7776931
    Abstract: 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 monophosphate esters and diphosphate esters exhibit surface-active properties that cause the inhibitors to self-associate at oil-water interfaces and inhibit interactions between organic acids in the oil with cations or cation complexes in the water. 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.

  • Patent number: 7373276
    Abstract: 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 CEF for a series of emulsions that differ substantially only in their internal phase volume ratio. A plot of CEF values as a function of the inverse of the internal phase volume ratio is characterized by a linear slope. Using the slope, a theoretical CEF value can be determined by extrapolating to where the inverse of the internal phase volume ratio is about one. The slope for a given emulsion series is associated with the relative energy barrier to flocculation and the theoretical critical electric field for a given emulsion series is associated with the relative energy barrier to coalescence. Comparative studies are performed using this method.

  • Patent number: 6815208
    Abstract: 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 facilitates meeting environmental guidelines while also minimizing chemical cost. The method includes: adding an oxygen scavenger to remove oxygen and prevent or minimize oxygen corrosion; raising the hydrotest water pH, typically in excess of pH 9.5; adding a biocide in reduced amount; and adding a scale inhibitor to inhibit scale.

  • Patent number: 6475431
    Abstract: A low toxic, biodegradable, water soluble and dispersant series of corrosion inhibitors are described. The method of inhibiting corrosion in aqueous medium by incorporating the inhibitor in PPM is provided. The corrosion inhibitor compromises an acrylic acid and chloroacetic acid adduct of 2-substituted imidazolines or primary, secondary or tertiary amines with carbon chain of twelve to twenty-two saturated or unsaturated carbon atoms. The molar ratio of acrylic acid to chloroacetic acid was methodically changed while keeping the concentration of imidazoline or the amine a constant. The product is made water soluble by raising the pH to 8-9 at the end of the synthesis by adding aqueous sodium hydroxide.

  • Patent number: 6383368
    Abstract: A metal salt removal procedure for use with a crude oil flow is disclosed. A small amount of water, and a caustic in the range of 7-12 pH, and preferably 9-12 pH, are injected to form water bubbles surrounded by oil. An ethylene oxide reacted with polypropylene glycol at 350° F. or so yields a water soluble demulsifier added at the rate of a few ppm to the water in oil mix. The added reaction product, a polyol, enables metal salt isolation in the water.

  • Patent number: 5611992
    Abstract: The present invention relates to blends of individual corrosion inhibitors with phosphate esters for protection of ferrous metals against attack by a corrosive environment. These blends are synergistically more effective than each of the individual corrosion inhibitors. The phosphate esters of the present invention are the reaction products of ethoxylated, propoxylated, or butoxylated alcohols or phenols with phosphating agents. Other corrosion inhibitors suitable for blending with the phosphate esters include fatty amines, poly amides, imidazolines, poly imidazolines, quaternary amines, poly quats and dimer, trimer, and polymeric acids. Phosphate esters may comprise any portion of the total amount of corrosion inhibitors in the blend, but the preferred concentration is from about 5 to about 50 weight percent phosphate ester. The corrosion inhibitor blends may be diluted to any concentration with solvents or other fluids as necessary for particular applications.
