  • Resistivity Measurement Through Metal Casing Using Magnetic Field and Magnetoacoustic Phenomena
    Publication number: 20110261647
    Abstract: Measurements of acoustic velocities are made through a case borehole in the absence and presence of an applied magnetic field. A formation resistivity parameter may be estimated from differences in the acoustic velocities.
    Type: Application
    Filed: June 9, 2011
    Publication date: October 27, 2011
    Applicant: BAKER HUGHES INCORPORATED
    Inventors: Leonty A. Tabarovsky, Vitaly N. Dorovsky, Yuriy A. Nefedkin, Kholmatzhon Imomnazarov

  • Method and apparatus of using crossed magnetic fields for measuring conductivity, permeability and porosity
    Patent number: 7500539
    Abstract: When a static magnetic field and a crossed oscillating field are applied, the deformation rate at a boundary between a fluid and a porous medium depends on the amplitudes of the applied magnetic fields (to be exact, on their product), electric conductivity, porosity, and permeability. Knowing two of the three enables determination of the third. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
