  • 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.

  • Publication number: 20090266547
    Abstract: Disclosed is a system for injecting an enzymatic fluid composition into a gas or gas and oil near-well bore having a wide temperature range. The enzymatic fluid composition is a treatment for reducing oil deposits, asphaltenes, waxes, scale, or other hydrocarbon materials in a gas well or a combination gas/oil well where the production of gas is greater than 50% on a barrel of oil equivalent (BOE) basis.

  • 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.

  • Patent number: 5492663
    Abstract: The invention provides a method by which the mold for a molded vehicle component can be engraved with a grain pattern to match the stretched grain pattern of an adjacent vehicle panel covered by a stretched vinyl sheet. According to the method, a grained vinyl sheet is stretched over a model of the vehicle panel so that the grained pattern of the vinyl is distorted. A portion of the vinyl sheet is then severed at the region to be occupied by the molded component and this severed portion of the vinyl sheet is used as a master for engraving the mold for the molded component.
