Technology advances mean we now understand where all our source and receiver positions are in real time for towed streamer surveys, and Andrew Long explains how they can be independently steered too. (PGS 2020)

The largest seismic vessels can now tow 18-20 streamers, and attention has turned to whether several sources should be used to improve data quality or improve survey efficiency. We break down the competing arguments into simple visual explanations, to show how different survey designs can be tailored for various geological challenges. (PGS 2020)
