FORMATION RESISTIVITY MEASUREMENT APPARATUS, SYSTEMS, AND METHODS

摘要

Apparatus, systems, and methods may operate to correct measured resistivity data for borehole effects to provide borehole-corrected apparent resistivity data for a non-invaded formation. Additional activity may include inverting the measured resistivity data or the borehole-corrected apparent resistivity data to provide non-invaded true resistivity values for the non-invaded formation, inverting the measured resistivity data to provide invaded true resistivity values for an invaded formation, determining true resistivity values for a geological formation associated with the measured resistivity data as a weighted combination of the non-invaded true resistivity values and the invaded true resistivity values, and operating a controlled device according to the true resistivity values for the geological formation.
