Abstract
G-22 MAPPING OF UPPER JURASSIC SANDSTONE IN THE BORG NORTH AREA USING ELASTIC INVERSION J. HELGESEN 1 Å. KARLSEN 2 Ø. RUNDE 1 and J. STEINDL 1 Summary 1 The Upper Jurassic Draupne reservoir sandstone in the Borg area is difficult to distinguish from the Draupne shale using seismic data mainly due to the small thickness of the sand and the wide variability of acoustic impedance in the shale. Through careful processing of the seismic data layer-based elastic inversion of partial stacks and 3D visualisation we were able to identify and map these sandstones using the estimated Poisson’s ratio and
