The increase in efficiency for marine streamer acquisition has been significant during the last<br>decade. The most efficient surveys have used configurations with 10 and 12 streamers and<br>two source arrays. Tow widths with up to 1350 m spread between the outer streamers were<br>successfully acquired fulfilling the survey objectives. With further improvements in vessel<br>streamer technology, we are experiencing a new trend focusing on improving data quality<br>using denser trace spacing.
