  • Enzyme Surfactant Fluids Used in Non-Gel Hydraulic Fracturing of Oil Wells
    Publication number: 20100300693
    Abstract: The present application describes improved total recovery of oil, condensate and associated gas in a subterranean formation such that said hydrocarbons are released by a hydraulic fracturing process with a non-gel hydraulic fracturing fluid that comprises an enzyme surfactant fluid with at least one anionic surfactant thereby forming a non-gel hydraulic fracturing fluid enzyme surfactant composition which is injected at 1 to 3 percent of total frac fluid during fracturing.
    Type: Application
    Filed: August 3, 2010
    Publication date: December 2, 2010
    Inventors: John L. Gray, Allan R. Hartman, Ronald Michael Herzfeld
  • Enzyme enhanced oil/gas recovery (EEOR/EEGR) using non-gel hydraulic fracturing in hydrocarbon producing wells
    Publication number: 20090062153
    Abstract: The present application describes enhanced recovery of oil and/or other hydrocarbons in a subterranean formation such that oil and/or hydrocarbons are released by a hydraulic fracturing process with a non-gel hydraulic fracturing fluid that comprises an oleophilic enzyme thereby forming a non-gel hydraulic fracturing fluid enzyme composition which is injected during an initial or later stage.
