Alexander Igorevich Fedorov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Radial waves in a borehole and stoneley waves for measuring formation permeability and electroacoustic constant
    Patent number: 9557440
    Abstract: A Stoneley wave is generated in a borehole in a saturated porous earth formation. Measurements are made of the velocity of motion of the formation and the fluid in the formation. The difference in the velocities is indicative of formation permeability. An additional measurement of the electric field at the borehole wall enables determination of the electroacoustic constant.
    Type: Grant
    Filed: July 17, 2009
    Date of Patent: January 31, 2017
    Assignee: BAKER HUGHES INCORPORATED
    Inventors: Vitaly Nikolaevich Dorovsky, Alexander Igorevich Fedorov, Yury Vadimovich Perepechko
