ABSTRACT:
Resistivity measurements at different radial depths of investigation obtained from time lapse resistivity data gained from multiple passes of a resistivity tool through a borehole are analyzed together to obtain indications of at least one of fractional flow, residual oil and water saturations, oil saturation, and water saturation in a formation. For each of the logging passes having resistivity measurements with multiple radial depths of investigation, filtrate loss into the formation is also obtained through joint inversion.
