  • Method for operating a couette device to create and study emulsions
    Patent number: 7581436
    Abstract: A method for generating and characterizing an emulsion. The method provides a Couette device having first and second cylindrical members that define an annulus between them. The second cylindrical member is rotatably driven with respect to the first cylindrical member. Two or more substances each in a non-emulsified state are injected into the annulus. The Couette device is operated in a first mode to generate an emulsion from the two or more substances. The Couette device is also operated in a second mode to measure various attributes of the emulsion.
    Type: Grant
    Filed: January 25, 2008
    Date of Patent: September 1, 2009
    Assignee: Schlumberger Technology Corporation
    Inventors: Dmitry Eskin, Shawn David Taylor, Hussein Alboudwarej, Joao Felix, Geza Horvath Szabo
