Abstract
Systems and methods for imaging properties of subterranean formations (136) in a wellbore (106) include a formation sensor (120, 200) for collecting currents (304A, 304B) injected into the subterranean formations (139) and a formation imaging unit (118). The formation imaging unit (118) includes a current management unit for collecting data from the currents injected into the subterranean formations (136) and a formation data unit (116) for determining at least one formation parameter from the collected data. The formation imaging unit (118) 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.
