Acquired Broadband Seismic and Its Value for an Interpreter and a Reservoir Geophysics

The seismic industry is constantly seeking of improving the contribution of seismic data to the upstream E&P workflow from seismic acquisition to reservoir modeling. In this paper, we review the experience we have in broadband seismic and illustrate how these benefits seismic interpreters and geoscientists involved in interpretation or quantitative seismic interpretation projects. One of the enduring objectives of the seismic industry has been the development of seismic solutions that are broader in term of frequency content, extending the range of both the low and high frequency sides without compromising one end or the other. Petroleum Geo-Services (PGS) since now 2007 is using a dual-sensor streamer acquisition system which provides broader seismic frequency bandwidth without any compromise in pre-stack data quality or acquisition efficiency. Results over the last seven years have demonstrated the benefits of this system in processing, seismic interpretation and reservoir geophysics. By presenting few case studies in different geographical and geological settings this paper seeks to illustrate the benefits to end-user practitioners in seismic interpretation and seismic reservoir characterization across a range of E&P asset development phases from exploration to appraisal and field development/optimization.
