In this study, an elastic prestack migration/inversion (M/I) scheme was applied to a 2-D seismic line collected in the Adriatic Sea. The objective was to use M/I images to describe a hydrocarbon reservoir, consisting of karstified, brine-saturated limestones. The M/I technique offers the benefit of extracting maximum information from seismic reflection data to describe, and in some cases characterize, the reservoir target. M/I images are calibrated with well data and represent approximate changes in P- and S-wave impedances across the reservoir. Combining these two images yields a Poisson's ratio image.
