Summary:
Multi-component recording of seismic data with two components and four components has been in use in shallow water environments for nearly three decades. The use of motion sensors for streamer marine acquisition has a much shorter history. The earliest system introduced by PGS in 2007 used a combination of hydrophones and gimbaled vertical geophones, but in recent years two additional systems have been deployed that also record the horizontal motion of the streamers in the crossline direction. The motivation for the introduction of the vertical sensor was to improve the spectral content of the data, while for the horizontal sensor it is to enable sensor rotation when gimbals are not being utilized. This paper describes the design considerations and characteristics of one of these systems, and compares seismic data acquired on a recent production survey and produced with either hydrophone-only or joint deghosting.
