f Why Accept One Sensor When You Can Have Two-Dual-Sensor Towed Marine Streamer Seismic?

Traditionally, towed marine cables measure the seismic wavefield using only pressure sensors (hydrophones). To image shallow targets the focus will be on resolution and enhancing the higher frequencies, normally achieved by towing the streamer more shallow in the water. Imaging of deeper targets the focus will be on penetration and enhancing the lower frequencies, this time achieved by towing the streamer deeper in the water. By introducing a dual sensor streamer PGS has now overcome this limitation making it possible to record broadband seismic data, both higher and lower frequencies, with a single acquisition configuration.
