Abstract
In one embodiment, a method includes receiving, via a processor, data from a plurality of imaging buttons disposed on a downhole tool within a borehole, generating, via the processor, a resistivity image, a permittivity image, a standoff curve, a rugosity index curve, a high-resolution image of a relationship between resistivity and permittivity of a section of a geological formation measured by the downhole tool, or some combination thereof based on the data, characterizing, via the processor, one or more vugs, one or more fractures, or some combination thereof based at least on the resistivity image, the permittivity image, the standoff curve, the rugosity index curve, the high-resolution image of the relationship between resistivity and permittivity, or some combination thereof, and identifying, via the processor, one or more rock types based at least on the high-resolution image of the relationship between resistivity and permittivity.
