The oil and gas exploration boom in offshore Brazil has driven the deployment of new acquisition strategies and processing technologies. The Campos basin has proven to be a challenging area for seismic imaging, because of its complex geology and deep pre-salt targets. By providing an improved low frequency response and a broader usable bandwidth, seismic data recorded using variable depth streamer acquisition appears to be an appropriate and promising solution for oil and gas exploration offshore Brazil. New acquisition technology can require optimisation of the processing workflow. We expose the need to take care with standard processing steps such as de-signature and demonstrate, comparing real images from streamer and variable depth streamer data, how new acquisition technology combined with advanced processing techniques is beneficial to pre-salt imaging in the Campos basin.
