oa The Value of Broadband Seismic from Dual-sensor Streamer for the Interpreter and Reservoir Geophysics

The seismic industry is constantly seeking ways of improving the contribution of seismic data to the upstream E&P workflow from seismic acquisition to reservoir modeling. We review recent developments in broadband seismic and illustrate how these add value for seismic interpreters and geoscientists involved in reservoir characterization or quantitative interpretation projects. In 2007 a dual-sensor streamer acquisition system was developed with the objective of providing broader seismic frequency bandwidth without any compromise in pre-stack data quality or acquisition efficiency. The increase in bandwidth is achieved by removing the sea-surface ghost at the receiver end via the principle of wavefield separation. 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 and optimization.
