Methods and Systems for Streamer Anti-Twist

摘要

Disclosed are methods and systems for enabling anti-twist functionality in marine geophysical streamers. An embodiment discloses a method comprising: towing a streamer behind a survey vessel in a body of water, wherein the streamer comprises rotation sensors and streamer rotation devices; receiving data from at least one rotation sensor indicative of streamer twist; and rotating a portion of the streamer with at least one streamer rotation device to reduce the streamer twist based, at least in part on the data.

主权项

1. A system for marine geophysical surveying comprising:
a streamer; geophysical sensors at spaced apart locations on the streamer, wherein the geophysical sensors are configured to generate signals in response to detecting energy emitted from one or more energy sources; streamer rotation devices at spaced apart locations on the streamer; and rotation sensors at spaced apart locations on the streamer.
