Filed:

Mar 13, 2003

Appl. No.:

10/388243

Inventors:

David A. Clayton - Seabrook TX, US
Shyam Kutty - Houston TX, US
Allen Nance - Fredericksburg TX, US

Assignee:

Input/Output, Inc. - Stafford TX

International Classification:

G01V001/38

US Classification:

367144

Abstract:

An in-water distributed control system for use in marine seismic survey. The system includes a shipboard interface and power supply coupled to an in-water subsystem via a high bandwidth communication link. The in-water subsystem includes a remote control module for generating firing commands based on synchronizing and position parameters transmitted by the interface. The remote control module transmits power, data, and commands to a plurality of gun control modules. Each gun control module operates an air gun. An individually addressable remote cut-off valve controls air to each air gun. Depth and pressure at the gun control module is sensed by at least one DT/PT module. An optional expansion unit provides additional DT/PT capability.

International Classification:

G01V001/52
H04B017/00

US Classification:

367 68, 367 13, 702 16

Abstract:

A graphical user interface (GUI) and control system for marine seismic data acquisition is described along with a method of real-time quality control of the seismic survey. The control system includes real-time data processing of individual source near-field measured signals and concurrent synthesis of array far-field signatures. The control system determines individual source out-of-specification conditions and computes far-field signatures based on an array configuration excluding the failed source. Source, array, and troubleshooting information are presented to a user in real-time over a GUI monitor to allow informed decision-making regarding continued and/or modified survey operations and operational parameters.

Abstract:

A graphical user interface (GUI) and control system for controlling and testing an acoustic source. The control system includes real-time data processing of individual source near-field measured signatures and synthesis of array far-field signatures. The control system determines individual source out-of-specification conditions and computes far-field signatures based on an array configuration and, when applicable, excluding failed sources. Source, array, and troubleshooting information are presented to a user in real-time over a GUI monitor to allow informed decision-making regarding continued and/or modified survey operations and operational parameters.
