Title: Method and system for increasing fold to streamer length ratio
Inventor: JACOBSEN NILS-ERIK
IPC: G01V1/38
Filed: 1999-04-16
Abstract: A method and system are provided for use in marine seismic data surveys to increase fold and offset without increasing streamer length or drag on the streamer boat.
