Abstract

Prestack inversion was performed on a 3D dataset over a North American carbonate play. The PSTM gathers were conditioned and then Bandwidth Extension (BE) was performed on the data extending the bandwidth from less than 2 octaves to more than 3.5 octaves. After initially inverting to Vp, Vs and density other rock properties were derived including Poisson's ratio and Young's, bulk and shear moduli. Results were cross plotted and geobodies built corresponding to the best reservoir rock.

Drilling results pre- and post-inversion will be discussed.
