  • Publication number: 20170327731
    Abstract: Methods for selecting a surfactant for treating a subterranean formation based on the performance of the surfactant and the characteristics of the subterranean formation and the treatment fluids that may be used to treat that formation are provided. In one embodiment, the method may comprise providing a treatment fluid, formation materials, hydrocarbon, and a plurality of surfactants, wherein the hydrocarbon is acquired from a subterranean formation; selecting at least two surfactants from the plurality of surfactants by determining whether each of the plurality of surfactants separates a mixture of the treatment fluid and the hydrocarbon; and selecting at least one surfactant from the at least two surfactants by determining whether the hydrocarbon displaces the treatment fluid from the formation materials in the presence of each of the at least two surfactants.

  • Publication number: 20170322132
    Abstract: Evaluating surfactants for use in downhole applications, especially surfactants with similar surface tension or interfacial tension values and wetting properties, may be achieved with a sensitive column test using a non-uniform particulate media therein. An exemplary method may include providing a column containing two types of particles that differ by at least one of: a mean particle diameter, a sphericity, and a chemical composition. Surfactant samples may be individually tested by passing the sample through the column followed by a displacement fluid, typically an oleaginous. The displacement rate and volume of the surfactant sample may be used to assess the surfactant's suitability for downhole applications.

  • Publication number: 20170003210
    Abstract: System and method for monitoring frac fluid flow through a column bed includes preparing a vessel (112, 440) with a column including a filtering member (120, 420), a column bed (114, 414) simulating a downhole environment, and a frac fluid (116, 416). Frac fluid (116, 416) is flowed through the column bed (114, 414) at an acceleration exceeding gravity for a predetermined period of time. The amount of liquid that flows through the column bed (114, 414) and that is recovered after the predetermined period of time is then determined.

  • Publication number: 20160273327
    Abstract: A method for controlling water passage from an interval undergoing hydraulic fracturing to another interval in the same or a different well bore. The method introduces a relative permeability modifier at a pressure sufficient to create or enhance at least one fracture and fracture face in the subterranean formation surrounding the interval during fracturing. The method can reduce the water passage between two or more intervals of a well bore and between two or more well bores. The method can reduce the amount of water produced from a well, which reduces the processing necessary to remove water from the hydrocarbons produced from the well.

  • Patent number: 8778910
    Abstract: The invention relates to concentrated liquid cleansing compositions in lamellar phase which possess a lotion-like appearance conveying signals of enhanced moisturization. The use of a specific ratio of synthetic anionic surfactant(s) and co-surfactant(s) to fatty acid(s) in a structured liquid product was found to improve lather production by moderating or eliminating the increase in viscosity upon dilution. In a further embodiment, specific small hydrophobic molecules were found to improve freeze/thaw stability and thereby cause the inventive composition to maintain noticeable moisturization signals.
