P265 Attenuation Analysis and Simultaneous Inversion as a Key Component in Prospect Evaluation M. Parks* (BG Group Ltd) K. Bardwell (BG Group Ltd) R. Nesbit (Schlumberger Oilfield UK Plc) & A. Alexander (Schlumberger Oilfield UK Plc) SUMMARY Prospect evaluation can benefit greatly from analysis of the acoustic and elastic rock properties combined with energy attenuation measurements at the target level. Seismically estimated rock properties can be used in conjunction with classical play fairway analysis to reduce risk in exploration drilling. In this paper we describe a comprehensive reservoir characterisation workflow undertaken on a Palaeocene Forties Sandstone prospect. We demonstrate that
