  • US Patent:
    7046112, May 16, 2006
  • Filed:
    Jan 26, 2004
  • Appl. No.:
    10/764781
  • Inventors:
    Evan L. Davies - Spring TX, US
    Luis E. San Martin - Houston TX, US
  • Assignee:
    Halliburton Energy Services, Inc. - Houston TX
  • International Classification:
    H01F 27/30
  • US Classification:
    336198
  • Abstract:
    The present invention is directed to a logging tool induction coil form having a coating layer, which is easy to form to tight tolerances, bonded to at least a portion of the outer surface of the ceramic hollow cylindrical core. A plurality of parallel circumferential grooves are machined into the coating layer. Since the coating material is easy to machine, the parallel circumferential grooves can be machined to the tight tolerances needed in logging applications at a fraction of the time and cost of machining ceramic-only forms.

  • International Classification:
    G01V 3/20
    G01V 3/24
  • US Classification:
    324366, 324370
  • Abstract:
    Oil-based mud imaging systems and methods having standoff compensation. In some embodiments, disclosed logging systems include a logging tool in communication with surface computing facilities. The logging tool is provided with a sensor array having at least two voltage electrodes positioned between two current electrodes energized by an excitation source to create an oscillatory electric field in a borehole wall. The two current electrodes are each shielded with conductive shields to prevent current leakage into the logging tool body. A common mode voltage is measured, and the phase and amplitude of the excitation source is controlled to reduce the difference between the common mode voltage and reference voltage of a voltage detector. The logging tool is further provided with electronics coupled to the voltage detector and the current electrodes to determine a differential voltage between the voltage electrodes and two current flows from separate ones of the current electrodes. From the differential voltage and multiple current flows, the computing facilities determine borehole wall resistivity, and may display the resistivity as a borehole wall image.

  • Abstract:
    An artificial neural network, ANN, and method of training the ANN for inversion of logging tool signals into well logs of formation parameters is disclosed. Properly selected synthetic models of earth formations are used to train the ANN. The models include Oklahoma and chirp type of formations. In each model parameter contrasts of from 10 to 1 to about 100 to 1 are included. Models including maximum and minimum parameter values spanning the operating range of the selected logging tool are included. Parameter contrasts at interfaces are limited to realistic values found in earth formations. The selected models are used to generate synthetic tool signals, which are then used as inputs to the ANN for training. When the ANN coefficients are properly adjusted to produce an output matching the original models, the ANN can be used for inversion of any real signals from the selected logging tool.

  • Abstract:
    An apparatus and method that provide steerable measurements of attenuation and phase difference are disclosed. In a preferred embodiment, a logging tool is provided with two triads of orthogonal receivers and a triad of orthogonal transmitters. A controller in the logging tool fires selected transmitters singly and in pairs, and determines measurements of ratios between signals received by the receiver triads. The measurement of sixteen ratios is sufficient to allow determination of attenuation and phase difference that would be measured by virtually steered receivers according to equations provided herein.

  • Abstract:
    An apparatus and method for performing high transverse resolution voltage measurements in downhole logging tools utilized to determine the resistivity of an adjacent portion of a borehole wall. Two current electrodes and are energized by an excitation source to create an oscillatory electric field in a borehole wall. The voltage drop from each voltage electrode in a row of laterally spaced voltage electrodes is measured relative to a shared voltage electrode longitudinally spaced from the row of electrodes. The differential voltage is used in combination with a measured current flow to determine a resistivity value for the borehole. A second row of laterally spaced voltage electrodes having electrodes laterally offset from the electrodes of the first row is included to provide high transverse resolution. A common mode voltage at the shared voltage electrodes is measured and utilized to minimize the resistivity measurement error.
