Worldwide Geophysical Data Library Now Available on Google Earth

TGS-NOPEC Geophysical Company utilizes popular mapping platform to provide easy access to their products and services around the globe.

Making a geophysical data library easily accessible is no simple task, especially for a company that juggles worldwide data acquisition from multiple survey methods.  However, TGS-NOPEC Geophysical Company (TGS) has managed to develop a great way to keep their data library updated and user-friendly at the same time with the Google Earth platform. Now anyone can simply visit http://products.tgsnopec.no/ and after a few simple steps, the entire breadth of the TGS data library is at their fingertips.

TGS is a principal resource for global, non-exclusive geoscientific data products and services in the oil and gas exploration industry. The company specializes in planning, acquiring and processing multi-client geophysical data in major and emerging offshore exploration plays worldwide.  The company's 2D and 3D seismic library is among the strongest, most diverse and highest quality in the marketplace, and Google Earth provides an ideal platform for exploring this data around the globe.

Navigating the Google Earth data library provides a glimpse of how countries worldwide have entrusted TGS to assist with licensing rounds and the preparation of regional data programs. This global presence, which includes offshore seismic surveys conducted in more than two dozen nations, is made possible by a diverse staff on three continents. Success in this competitive marketplace reflects the company's reputation for benchmark quality and personalized service. 

2D and 3D Seismic Data
TGS' global multi-client library of 2D and 3D seismic data includes surveys from mature basins, emerging regions and frontier exploration zones. Since its founding, TGS has embraced the multi-client model, acquiring over 2,000,000 line kilometers of 2D data and 88,000 square kilometers of 3D seismic data in North and South America, Europe, Africa and Asia.  Maps of these surveys can be viewed by navigating the TGS data library through Google Earth.

  This 385 block survey will be the first available Speculative Reverse Time Migration. A preliminary version of 62 blocks is available and the entire area is expected to be complete in December2008. Available now for delivery are the Prestack Time Migration,Wave Equation and Kirchhoff Prestack Depth Migration volume.
• MC Revival Kirchhoff 3D
  This product utilizes 242 checkshots to create an anisotropic velocity model, turning wave Kirchhoff migration to pick two tops and bases of salt and subsalt tomography.

Gravity, Magnetics and CSEM
TGS offers value-added gravity and magnetic data products to complement its regional interpretations and seismic data packages.  These products are also available for viewing on Google Earth.

Workstation Services
The TGS data management team offers project data loading, platform transfer and workstation-related computing tasks. Exploration companies have realized facilities and resource cost savings with TGS handling the physical storage and management of their data tapes and materials.

The data management team includes experts who specialize in the loading of geoscientific data into leading seismic workstation platforms.  This provides a cost-effective alternative to the time-intensive and error-prone process of converting exploration data from one workstation format to another.  

Imaging Services
The Imaging Services group at TGS has very quickly become one of the premier providers of Seismic Data Processing and Depth Imaging.  The company's ongoing processing projects are viewable by clicking on the corresponding areas in Google Earth.

TGS' recent dynamic growth has been fueled by the acquisition of high end processing service companies (NuTec Energy Services in 2004 and Parallel Data Systems in 2007) and integrating them within the TGS organization. In addition to providing industry leading 3D pre stack depth migration algorithms, the company continues to add to its versatile data processing toolbox with advanced noise and multiple removal techniques, tomographic solutions and anisotropic estimation methods.

Developing and supporting the PRIMA software platform is an ongoing effort made by TGS. PRIMA provides the experienced processing geophysicists with a state of the art, user friendly and powerful environment for efficient processing, data analysis and review.

The most recent large-scale pre-stack depth migration project undertaken by TGS Imaging Services group was designed to take advantage of the most advanced imaging technologies available. These were applied to 660 block Mississippi Canyon 3D survey in the Gulf of Mexico and include:

• Anisotropic parameter estimation, calibrated with 247 wells
• Revised Interpretation
• Subsalt Tomography
• Industry leading 3D Anisotropic Kirchhoff PSDM for high quality and accuracy

World of Opportunities
Browsing the TGS data library on Google Earth provides a glimpse of the company's strong presence in the global subsurface data industry.  The company has acquired and processed data all over the world, and this user-friendly platform is an ideal way to navigate their vast array of assets.  TGS will continue to expand their library of geoscience data and services for energy companies looking to explore a world of opportunities.
