  • HYDROCARBON FLUID FLOW IMPROVER
    Publication number: 20140224495
    Abstract: Disclosed herein is a fluid flow improver comprising a branched dendritic core comprising a first quaternary carbon center bonded to four second carbon atoms, wherein at least three of the four second carbon atoms are individually bonded to one or more chain extender ligands to produce the branched dendritic core, wherein the branched dendritic core has greater than or equal to about 16 terminal hydroxyl groups, and wherein at least one of the terminal hydroxyl groups is esterified with at least one carboxylic acid moiety comprising from 6 to 30 carbon atoms. Methods of inhibiting deposition of paraffin and reducing pour point temperature of a hydrocarbon fluid are also disclosed.

  • KINETIC HYDRATE INHIBITORS WITH PENDENT AMINO FUNCTIONALITY
    Publication number: 20140142002
    Abstract: A kinetic gas hydrate inhibitor is provided as a polyester polymer with a plurality of amino or ammonium groups pendent directly from the backbone. A composition containing concentrated kinetic inhibitor is injected into gas wells, or into other systems involving transporting liquid gas mixtures through a conduit. Use of the kinetic inhibitor prevents formation of gas hydrates under conditions of temperature and pressure where they would otherwise occur.

  • METHOD OF PREDICTING/OPTIMIZING HYDROGEN SULFIDE SCAVENGING CAPACITY AND REDUCTION OF SCALE FORMATION
    Publication number: 20110130298
    Abstract: A method of optimizing a hydrogen sulfide scavenger blend that includes selecting a hydrogen sulfide scavenger blend comprising at least two hydrogen sulfide scavengers; determining a scavenging capacity for the blend; modifying at least one blend parameter based on the determined scavenging capacity; redetermining the scavenging capacity for the modified blend; and selecting an optimized blend from the blend and the modified blend is disclosed.
