  • Workflow to use borehole completion as antenna for geophysical applications
    Patent number: 10365394
    Abstract: An electromagnetic geophysical survey is performed by transmitting current from a first source into earth, the first source being located in a borehole. An electromagnetic field generated by the current transmitted from the first source is measured to create subsurface data. In addition, a background model is constructed and a leakage current distribution is calculated. A resistivity distribution of the earth is calculated using the subsurface data, the background model and the leakage current distribution, with the leakage current distribution being used as a source current distribution.

  • System and method for performing distant geophysical survey
    Patent number: 10309214
    Abstract: A downhole drilling tool is adapted to be placed in a borehole formed in the earth. The downhole drilling tool has mounted thereto at least one of a transmitter for generating and a receiver for sensing at least one component of an electromagnetic field within a distant earth region. The tool also has a device configured to acquire subsurface data from the at least one component of the electromagnetic field; and a device configured to calculate a resistivity distribution of the distant earth region from the subsurface data. A geophysical survey is performed with a downhole drilling tool by transmitting at least one component of an electromagnetic field through the distant earth region; acquiring subsurface data from the at least one component of the electromagnetic field; and calculating a resistivity distribution of the distant earth region from the subsurface data.
