摘要： A method for inverting dielectric logging tool measurement data to estimate an electrical characteristic of an earth formation includes: receiving measurement data from the logging tool having a transmitter antenna and receiver antennas spaced known distances from the transmitter antenna; establishing an equation relating magnetic field measurements made by the receiver antennas to the distances and a wave vector; establishing an error equation that quantifies a difference between the magnetic field measurements made by the receiver antennas to magnetic field measurements made by the receiver antennas that would be obtained with an estimated formation electrical characteristic; calculating an error using the error equation for an initial estimated value of the wave vector that comprises a term having a first number multiplied times a second number of radians to provide a plurality of calculated errors; and determining a minimum error from the plurality of calculated errors to estimate the electrical characteristic.

摘要： Multi-array laterolog tool systems and methods acquire a set of array measurements sufficient to provide laterolog tool measurements of differing array sizes. Such systems and method offer multiple depths of investigation while offering greater measurement stability in borehole environments having high resistivity contrasts. In at least some system embodiments, a wireline or LWD tool body has a center electrode positioned between multiple pairs of guard electrodes and a pair of return electrodes. The tool's electronics provide a current from the center electrode to the pair of return electrodes and currents from each pair of guard electrodes to the pair of return electrodes. Each of the currents may be distinguishable by frequency or distinguishable by some other means. This novel arrangement of currents provides a complete set of measurements that enables one tool to simultaneously emulate a whole range of laterolog tools.

摘要： A method for determining a dip of a geological structure in a subterranean formation, involves generating, using a 3D resistivity analyzer, a first intermediate result describing the dip of the geological structure based on 3D resistivity data collected from a borehole penetrating the subterranean formation. The method further involves generating, using a borehole image analyzer, a second intermediate result describing the dip of the geological structure based on a borehole image collected from the borehole. The method further involves generating, by a computer processor combining the first intermediate result and the second intermediate result based on a pre-determined criterion, an integrated result describing the dip of the geological structure.

摘要： Resistivity logging tool module systems and methods enable efficient logging string assemblies and logging operations. In some of the disclosed embodiments, a resistivity logging tool module includes a mandrel with a connector section at each end and a ring support section between the connector sections. The resistivity logging tool module also includes a composite layer disposed around the ring support section. A set of ring electrodes is positioned along the ring support section around the composite layer, wherein the composite layer electrically isolates the ring electrodes from the ring support section. One of the modules of the multi-module resistivity logging tool includes an adaptor in an isolation joint configuration with one of its connector sections. A related assembly method includes obtaining a mandrel with a connector section at each end and a ring support section between the connector sections. The method also includes disposing a composite layer around the ring support section. The method also includes moving a set of ring electrodes to a position along the ring support section, wherein the composite layer electrically isolates the ring electrodes from the ring support section. One of the modules of the multi-module resistivity logging tool includes an adaptor in an isolation joint configuration with one of its connector sections.

摘要： A method and system for producing look-ahead profiles measurements includes positioning an energy transmitter, such as a transmitting antenna, proximate to a borehole assembly tool. One or more energy receivers, such as receiving antennas, are positioned along a length of the borehole assembly. Next, energy is transmitted to produce look-ahead scans relative to the borehole assembly tool. Look-ahead graph data with an x-axis being a function of a time relative to the position of the borehole assembly tool is generated. The look-ahead graph is produced and displayed on a display device. The look-ahead graph may track estimated formation values based on earth models. The estimated formation values are displayed below a tool position history line that is part of the look-ahead graph. The estimated formation values in the look-ahead graph may be based on inversions of resistivity data from the look-ahead scans.
