  • Methods for increase gas production and load recovery
    Patent number: 8946130
    Abstract: Methods are disclosed for improved sand control, fines control, load recovery and well productivity, where the compositions comprise reaction products of an amine and a phosphate-containing compound.
    Type: Grant
    Filed: May 12, 2009
    Date of Patent: February 3, 2015
    Assignee: Clearwater International LLC
    Inventors: Frank Zamora, Sarkis R. Kakadjian, Erin Fitzgerald, Tina Garza
  • Enhancing drag reduction properties of slick water systems
    Patent number: 8841240
    Abstract: Novel slick water fracturing fluid compositions are disclosed, where the compositions including with slick water fracturing compositions including a partially hydrolyzed polyacrylamide polymer system within invert emulsion and an effective amount of a friction reducer booster system, where the effective amount is sufficient to reduce a drag friction of the composition by an additional amount of at least 5% in the first 30 seconds of evaluation in high salinity and low temperature environments.
