System and Method for Imaging Subterranean Formations

摘要

Systems and methods for imaging properties of subterranean formations in a wellbore include a formation sensor for collecting currents injected into the subterranean formations and a formation imaging unit. The formation imaging unit includes a current management unit for collecting data from the currents injected into the subterranean formations and a formation data unit for determining at least one formation parameter from the collected data. The formation imaging unit also includes an inversion unit for determining at least one formation property by inverting the at least one formation parameter. The inversion unit is suitable for generating an inverted standoff image and an inverted permittivity image for comparison with a composite image of the formation imaging unit.

1. A formation imaging unit for imaging properties of at least one subterranean formation in a wellbore at a wellsite, the formation imaging unit comprising:
a current management unit for collecting data from at least two currents injected into the at least one subterranean formation, the at least two currents having at least two different frequencies; a formation data unit for determining at least one formation parameter from the collected data; and an inversion unit for inverting the at least one formation parameter to provide one or more of an inverted standoff image and an inverted permittivity image.
