The demand for better seismic data has increased in the search for new offshore energy resources. The launch of multisensor towed streamer technology in 2007 can be considered as a key milestone in marine seismic acquisition and imaging technology development (Widmaier et al., 2015) as high resolution imaging and quantitative interpretation has clearly benefited from the availability of true broadband data. Recent successful applications of full waveform inversion (Shen et al., 2017) are another breakthrough for seismic exploration technology. Longer offsets, improved near-offset sampling, higher trace density, denser spatial sampling, and larger azimuthal coverage are often referred to as the desired ingredients of modern marine seismic data. Innovative and smart technical solutions are required to meet such demands in a cost-effective manner. We will discuss how streamer and source geometries can be modified to address modern exploration objectives and geophysical challenges. Will novel solutions become the new paradigm in towed streamer acquisition?
