  • Induction resistivity imaging principles and devices in oil based mud
    Patent number: 7299131
    Abstract: An induction logging tool having transmitter and receiver antennas is used to make measurements of earth formations. The antennas may be mounted on the mandrel of a bottomhole assembly for MWD applications, or may be pad mounted for wireline applications. The induction measurements are inverted using a linearized model. The model parameters are determined in part from caliper measurements.
    Type: Grant

    Date of Patent: November 20, 2007
    Assignee: Baker Hughes Incorporated
    Inventors: Leonty A. Tabarovsky, Alexandre Bespalov, Mikhail Epov

  • Method of determining formation anisotropy in deviated wells using separation of induction mode
    Patent number: 6636045
    Abstract: Measurements are made with a multicomponent induction logging tool in earth formations in a borehole inclined to earth formations. A combination of principal component measurements is used to determine the horizontal resistivity of the earth formations. The determined horizontal resistivities are used in a model for inversion of other components of the data to obtain the vertical formations resistivities. When multifrequency measurements are available, frequency focusing is used.
