  • Method for determining weight concentration of clay in a sample of a porous medium
    Patent number: 9399911
    Abstract: For the purpose of determining a weight concentration of a clay material in a porous medium sample, a specific active surface area of the clay material and an initial specific active surface area of the porous sample are measured. A water solution of the clay material is pumped through the sample and a specific active surface area of the sample of the porous medium is measured after the pumping. Then, the weight concentration of the clay material is calculated.
    Type: Grant
    Filed: August 30, 2013
    Date of Patent: July 26, 2016
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Dmitry Mikhailov, Valery Vasilievich Shako, Evgeny Chuvilin, Tatiyana Buida
