New Gabon survey demonstrates how better design delivers better data

The quality of the seismic data you record depends on the quality of the energy generated by the source, how it interacts with the subsurface and the ability to record all the effects of those interactions. To obtain the required response from the reservoir it is necessary to start with the right sound, at the right level, from the right angle. This requires the use of the right survey design, with the right equipment and the right acquisition methods, as well as preserving all the recorded information through advanced broadband processing and imaging. By integrating all the available geological knowledge with existing gravity and velocity information it is possible to design the optimum acquisition parameters for a survey. This integrated approach was used to design, acquire and process the new 25,000-km2 broadband multi-client 3D survey offshore Gabon, that covers the five blocks on offer in Gabon’s new deepwater license round.
