A method for enhancing measurement resolution is disclosed. In one embodiment,the method includes (1) obtaining multiple measurement samples at each ofmultiple positions along a borehole; (2) extracting reference index samplesfrom the set of measurement samples; (3) determining a difference between eachof the reference index samples and corresponding modeled index samples; and(4) updating a set of enhanced index samples based on the difference. Theindex samples are preferably chosen to be representative of the measurementsamples obtained at each position, and accordingly, may be selected ones ofthe measurement samples, or alternatively, may be averages of the measurementsamples. The aforementioned modeled index samples may be found fromapplication of a predetermined tool response to the enhanced index samples,which in turn, may be found by iteration. Once the difference has been reducedbelow some threshold, the relationship between the enhanced index samples andthe reference index samples may be used to calculate a deconvolution filterfor all of the original measurement samples from the borehole. When applied tothe original measurement samples, the deconvolution filter producesmeasurement samples having an enhanced resolution.
