MARINE SEISMIC STREAMER SYSTEM CONFIGURATIONS, SYSTEMS, AND METHODS |
摘要 |
Methods for determining by acoustic ranging relative positions of marine seismic streamers in a network of streamers are described, as well as streamer configurations and systems which overcome weak or non-existent acoustic positioning signals. The acoustic network includes a plurality of acoustic transceiver pairs, and the methods include implementing a network solution-based reconfiguration of the acoustic transceiver pairs. When the network of streamers changes more than a critical amount, the network is reconfigured, the critical amount being when the network solution-based reconfiguration is no longer adequate to provide enough acoustic signals to give reasonable relative positions of the acoustic transceiver pairs in the network due to their spatial relation. |
