TGSinBrief
TGS and NOPEC Yesterday
Former U.S. oil company executives organized TGS Geophysical Company in 1981
in Houston, Texas and built what became the dominant 2D multi-client data library
in the Gulf of Mexico. Former Norwegian oil company executives organized NOPEC
International (NOPEC) in 1981 in Oslo, Norway and started the first of many highly
successful multi-client surveys with a Central Graben regional project in the North
Sea. In 1997 NOPEC became publicly traded on the Oslo Stock Exchange.
TGS Today
Recognizing a need for high quality, regional, multi-client seismic surveys and a
win-winopportunityforinvestors,customersandemployees,theHoustonandOslo-
based companies merged in June 1998, forming TGS-NOPEC Geophysical Company
(TGS). Since that time, TGS has set the standard for multi-client geoscientific data
acquired around the world. TGS has a firm commitment to high quality products
and exemplary customer service. A staff of experienced professionals ensures TGS
delivers on its commitments.
Global Strength and Experience
TGS has acquired 2D and 3D multi-client seismic data in North
and South America, Europe, Africa, Asia, Australia and the
Arctic. The data acquired through a multi-client project is
ownedbyTGS.Thedataisthenlicensedtomultiplecustomers
through a non-transferable data license. The concept of multi-
client data is widely applied throughout most hydrocarbon
exploration and production regions in the world. It is
appreciated by the oil and gas companies as a cost-effective
and critical tool, used to evaluate hydrocarbon potential and
minimize risk in both mature and frontier exploration areas.
Using the multi-client model, TGS plans the seismic surveys,
coordinates government regulations and solicits funding
from the oil industry. Upon achieving an acceptable level of
pre-funding from industry as well as governmental and land
owner approval, TGS then finances and carries out the survey.
The resulting data is provided to the initial pre-funding parties
but is also licensed to additional clients interested in the area.
This concept provides benefits for all parties involved:
The oil companies get access to modern, high-quality
geophysical data at a lower cost.
Local governments benefit from the availability of high
quality data which attracts competitive interest in the area.
Over a period of time, TGS receives a higher return than
acquiring the data on a traditional contract basis where
the oil company would ultimately own the data.
The location of TGS’ multi-client data can be viewed through
the data zone map on the Company’s website at www.tgs.
com. Data from marine, land, ocean bottom cable (OBC),
transition zone and wide azimuth (WAZ) acquisition methods
are processed by TGS’ geophysicists who specialize in 2D
and 3D data with products and services including time, depth
and anisotropic imaging.
TGS has the industry’s largest collection of online well data in
areas within North America, South America, Europe, Russia
and Africa. TGS offers interpretation studies and services
that integrate seismic, well logs, biostratigraphic data,
core data and other geoscientific data to create basin wide
regional frameworks. These geological products are also
provided on a multi-client basis through subscription basis
or data license.

10. Reservoir
Enlightening the Reservoir®
Reservoirs rarely behave as predicted and modelled. Under-
standing reservoir behavior using frequent and recently
acquired data that is capable of discerning small changes
in reservoir attributes enables TGS’ clients to increase
production and make the most effective IOR decisions to
maximize production whilst minimizing lifting costs.
Implementing a PRM solution leads to increases in total
recovery factor, increases in reserves, reduced drilling
costs, less produced water and faster data-based decisions
to meet the expectations of stakeholders in each field and
operating company.
TGS provides data solutions that assure oil and gas operators’
reservoir production and the highest payback for Increased Oil
Recovery (IOR) schemes.
This is achieved through the deployment of Permanent Reservoir
Monitoring(PRM)solutionsthatcollectseismicinformation about the
behavior of the reservoir, enabling increased production and reserves
at lower cost and risk throughout the production life of a field.
By installing a Stingray®
fiber-optic sensing system permanently
on the seabed, operators are able to acquire high fidelity, four-
component, time-lapse data (4C/4D) on a frequent basis. “Listening

Stingray PRM Systems
Stingray PRM systems comprise a permanently installed array of reliable four-component (4C), passive fiber-optic sensors,
rigorously tested and qualified to military standards. Each Optical Sensing Unit (OSU) consists of one hydrophone and three
orthogonally-mounted accelerometers.
With no subsea electrical power requirements and a low fiber count, the seabed array is connected through a small riser
cable to the Stingray Recording System (SRS) situated on the platform, FPSO, or tied-back to a remote host facility up to 500
km away. The SRS communicates with the sensors by pulsing light into the array and receiving and decoding the returning
signals to provide full-wave seismic imaging data for detailed reservoir characterization and monitoring.

11. Reservoir
The Stingray system’s simple design delivers efficient manufacturing, delivery, installation
and operation, as well as operational performance. In common with experience in the
telecommunications industry which has relied on optical fibers for over 30 years, TGS’ optical
sensing systems offer a step-change in reliability, proven by the 11-year seabed operation of
a military sensing system based on the same technology and backed by a warranty.
Amongst other applications, the system can be used to identify bypassed compartments, monitor
flood fronts, plan infill drilling locations and sweep remaining oil more effectively.
Field-wide Monitoring
Highly scalable for large field implementations, the Stingray system can be used to acquire
active and passive data for reservoir management decision making as part of an Enhanced Oil
Recovery program. The system benefits from the industry’s simplest, most robust fiber-optic
architecture. Sensor lines connected in pairs allow bi-directional operation with no degradation
in system performance, providing resilience from external events such as severing of a cable.
The system’s 180 dB dynamic range ensures high quality data by allowing full recovery of
direct source arrivals.
Well Zone Monitoring
The modular Stingray system is designed to help oil and gas
operators address a variety of focused reservoir surveillance
requirementssuchaswellintegrity,hydraulicfracturemonitoring
or cuttings disposal monitoring. By permanently installing a
small Stingray 4C seismic sensing array on the seabed over
the target area, operators benefit from high quality active and
passive micro-seismic data to support production management
decisions, as well as detect more localized changes in behavior
by listening to real-time reservoir responses.
Deepwater Reservoir Monitoring
Ever-increasing reservoir complexity, coupled with more
difficult fluids and recovery from deeper waters, all challenge
the need for optimal data quality and 4D detectability.
Leveraging the efficient optical architecture of its proven
technology, the Stingray system is qualified for deepwater.
TGS is engaged in a collaborative program to develop the
patent-pending equipment and methods required to install
Stingray optical sensing arrays efficiently in water depths up
to 3,000 m. This will enable cost-effective seismic reservoir
monitoring in deepwater and obstructed areas as well as
reduce engineering and reservoir risk.
4D Data Acquisition and Processing
TGS provides dedicated, repeatable and cost-effective 4D
acquisition through strategic alliances with specialist providers
of containerized source solutions specially designed for PRM
projects. Acquisition partnerships concentrate on maximizing
synergies and creating a stronger combined offering in order
to optimize project execution, turnaround and data quality. The
significant acquisition activity and source vessel utilization by
TGS can also be leveraged to provide source vessels from the
long-term charter fleet when needed.
Seismic data quality control is carried out with TGS’
proprietary software developed to monitor the quality of
system performance, acquisition activity and the integrity of
the acquired data. Close integration of seismic quality control
and 4D processing ensures high quality data whilst improving
acquisition and processing turnaround time. By applying TGS’
industry leading depth imaging technology to 4D processing
development, TGS focuses on the reduction of 4D noise and
the preservation of high fidelity 4D signals to provide better
and more targeted 4D imaging.
