  • Patent number: 11060397
    Abstract: An example method includes disposing a carrier in a borehole in an earth formation. The carrier includes a logging assembly for performing a formation evaluation of the earth formation using a sensor in proximity to a borehole wall of the borehole, fluid being disposed at least partially between the sensor and the borehole wall. The method further includes estimating an apparent dielectric loss angle of the fluid to determine a stand-off effect caused by the fluid. The method further includes estimating a formation dielectric loss angle and determining a formation resistance based at least in part on the formation dielectric loss angle. The method further includes adjusting the formation evaluation based at least in part on the estimated formation resistance that accounts for the stand-off effect caused by the fluid. The method further includes performing a wellbore operation based at least in part on the adjusted formation evaluation.
