Streamer design for geophysical prospecting

摘要

PGS-13-01 US An apparatusis disclosed that includes a solid-core streamer with particle motion sensors disposed within the solid core.Some embodiments may additionally include one or more pressure sensors that are disposed outside of the solid core.In some embodiments, the apparatus may also include one or more electromagnetic sensorsAlso disclosed are various methods of operating an apparatus that includes a streamer with particle motion sensors disposed within the solid core of the streamer. A vessel towing a solid-core streamer including particle motion sensors in the center of the solid core and pressure sensors outside the solid core A seismic energy source sending a seismic wavefield through the body of water to subterranean formations below the body of water The pressure sensors transmitting signals indicative of pressure variations and the particle motion sensors transmitting signals indicative of at least one component of particle motion The transmitted signals of the pressure sensors and the particle motion sensors being analyzed to determine up-going and down-going seismic wavefields Producing a geophysical data product
