Resolution and imaging of complex reservoirs - the value of broadband seismic via dual-sensor streamer acquisition

The seismic industry is constantly seeking ways of improving the contribution of seismic data to the upstream Exploration and Production workflow from seismic acquisition to reservoir modeling. We review recent developments in broadband seismic and illustrate how these benefit seismic interpreters and geoscientists involved in reservoir characterization or quantitative interpretation projects. Petroleum Geo-Services (PGS) launched in 2007 a dual-sensor streamer acquisition system developed with the objective of providing broader seismic frequency bandwidth without any compromise in pre-stack data quality or acquisition efficiency. Results over the last five years have demonstrated the benefits of this system in processing, seismic interpretation and reservoir geophysics. Case studies from different geological settings 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.
