US Patent:
8520468, Aug 27, 2013
Filed:
Jul 16, 2012
Appl. No.:
13/550001
Inventors:
Daniel B. Seale - New Orleans LA, US

Assignee:
ION Geophysical Corporation - Houston TX
International Classification:
G01S 1/38
US Classification:
367 19, 367 16
Abstract:
A method and system for controlling the shape and separation of an arrangement of streamers towed behind a survey vessel. Each streamer is steered laterally by lateral steering devices positioned along its length at specific nodes. Each streamer is driven by its lateral steering devices to achieve a specified separation from a neighboring streamer. One of these actual streamers, used as a reference by the other actual streamers, is steered to achieve a specified separation from an imaginary, or ghost, streamer virtually towed with the actual streamers.
