  • Formation resistivity imager with reduced leakage to mandrel
    Patent number: 8972193
    Abstract: A method of estimating a parameter of a formation contacting a borehole with an instrument that includes a mandrel and a pad includes providing a measurement voltage to the pad; applying a biasing voltage to the mandrel while the measurement voltage is applied to the pad; measuring a received current during at least a portion of time the measurement voltage is provided; and estimating the parameter based on the received current.
    Type: Grant
    Filed: March 5, 2012
    Date of Patent: March 3, 2015
    Assignee: Baker Hughes Incorporated
    Inventors: Gregory B. Itskovich, Stanislav Wilhelm Forgang, Assol Kavtorina
  • Concentric buttons of different sizes for imaging and standoff correction
    Patent number: 8786288
    Abstract: Disclosed is a method of estimating a property of an earth formation penetrated by a borehole. The method includes conveying a carrier through the borehole and performing a plurality of electrical measurements on the formation using a sensor disposed at the carrier and having a plurality of electrodes disposed in a concentric arrangement wherein a standoff distance between the sensor and a wall of the borehole has an influence on each electrical measurement in the plurality of electrical measurements. The method further includes determining an impedance for each electrical measurement in the plurality of electrical measurements and inputting the determined impedances into an artificial neural network implemented by a processor. The artificial neural network outputs the property wherein the outputted property compensates for the influence of sensor standoff distance on each electrical measurement in the plurality of electrical measurements.
