TGS is pleased to provide information regarding the upcoming license rounds in the Gulf of Mexico. The Bureau of Ocean Energy Management (BOEM), a division of the Department of the Interior, publishes the dates of the lease sales in the federal register 60 days prior to the sale. The lease sales are typically held in March, August and December.

The Brazilian National Petroleum Agency (Agência Nacional do Petróleo - ANP) announced the 11^th Licensing Round for concession blocks in Brazil on 24 April 2011.

The Canada – Nova Scotia Offshore Petroleum Board announces Results of Call for Bids NS11-1.

This line is from the TGS-Nopec and Schlumberger Brasil '99/2000/2001 non-exclusive seismic survey offshore Brasil. The survey, the largest of its kind in the World, includes over 200,000 line kilometers of seismic, gravity and magnetic data and covers the primary deep water sedimentary basins in south-east and northern offshore Brasil.

TGS has recently completed an additional 48,385 kilometers out of a total of 102,931 kilometers of new pre-stack depth processing for the Brasil offshore southern basin. This new depth project includes a carbonate tomography update that isolates the carbonate section above salt.

This depth imaging project includes 127,950 kilometers of 2D data in the Santos, Campos, and Espírito Santo Basins. Wave-equation and Kirchhoff versions are available.

TGS has reprocessed 16,028 km of 2D data in the Foz do Amazonas Basin, offshore Brazil.

East Newfoundland Orphan Basin The East Newfoundland Orphan Basin is currently in the spotlight with the 2003 call for bid No. NF03 1 closing on December 17, 2003.

The Freedom, Liberty, and Justice WAZ projects are now complete and ready for the upcoming Central Gulf of Mexico sale in June of this year.

TGS has Reverse Time Migration (RTM) fast-track data available in the Justice project.

The Deep Resolve 3D survey was designed and acquired to improve the image of the deep section of the continental shelf in the Gulf of Mexico.

The Deep Shelf Interpretation Project is a regional, evergreen interpretation project covering 3500 OCS Blocks of the Louisiana Shelf, Flex Trend and into the Deep Water protraction areas.

Approximately 100 OCS blocks of newly acquired Ocean Bottom Cable data in the Main Pass Viosca Knoll areas of the Gulf of Mexico.

The eMC3D survey is an eastern extension to the existing 3D coverage that TGSN has in Mississippi Canyon, Gulf of Mexico. The combination of these surveys provides a seamless regional 3D program covering over 900 OCS blocks (over 20,000 sq kms)

The line of the month is an RTM image from the recently completed Freedom Wide Azimuth 3D depth survey.

Hernando 3D is located in the eastern central Gulf of Mexico.

Mississippi Canyon 3 D Revival is a new Kirchhoff Pre Stack Time Migration reprocessing project, encompassing 627 OCS Blocks in Mississippi Canyon. This project is one of the largest 3 D seismic programs ever recorded in North America.

TGS-NOPEC is renewing it's commitment to the Mississippi Canyon Area of the Gulf of Mexico with the 3D Mississippi Canyon Revival project. This 3D survey was originally acquired in 1999 2000 with 8,000 meter streamer offsets.

TGS-NOPEC Geophysical Company (TGS) has completed the acquisition of a multi client 3D survey in the Gulf of Mexico. The survey known as “Orion”, is predominantly located within the “181 South” area, an area that has been off-limits to exploration until most recent 5-year leasing plan announced by the MMS.

This month's data example is from the Phase 45 project in the Gulf of Mexico. This is one of the largest 2D surveys in the world with slightly less than 100,000 total kilometers acquired.

This Line of the Month is from TGS’ SAKE 2D project. Located in DeSoto Canyon in the northeastern Gulf of Mexico, this project consists of over 5000 miles of data.

The Gulf of Mexico has been a core area for TGS for over 25 years. The Sophie's Link 3D is a new 179 OCS block project that links the Grand Isle and Ewing Bank areas (Deep Resolve 3D) to the West Delta and Mississippi Canyon areas (Mississippi Canyon 3D).

The line of the month is from TGS’ Sophie’s Resolve multi-client 3D survey in the Gulf of Mexico. The Gulf of Mexico Louisiana Shelf is a proven hydrocarbon province. 9000 meter offsets and 13 second records were acquired with streamers and with Ocean Bottom Sensors to achieve the best 3D coverage around existing infrastructure. TGS has taken clients to new depths with anisotropic pre-stack depth migrations to imaging down to 16 kilometers. Over 400 wells were utilized in developing the best anisotropic velocity model. 

The Gulf of Mexico Liberty WAZ project is now complete.  This project, combined with the Freedom WAZ project, accounts for over 19,500 km² of wide azimuth 3D coverage completed this year.

A regional deepwater interpretation project based on TGS Phase 45 PSDM data. The project, now complete, interprets key horizons over 7,200 deepwater Gulf of Mexico blocks using in excess of 100,000 KM of Kirchoff and Wave-equation processed 2D long-offset data.

TGS has recently completed 17670 miles of new Phase 51 2D acquisition with pre-stack time and depth processing in the Lloyd Ridge, Henderson, and Florida Plain areas of the Gulf of Mexico.

TGS has been a leader in offshore Canada with deepwater 2D grids that cover the Nova Scotia, Newfoundland, and Labrador offshore areas. TGS has completed over 160,000 kilometers of 2D pre-stack depth migrated data in the Gulf of Mexico, Bahamas, Canada, and Brazil.

Since 1999 TGS NOPEC has acquired more than 18,000 km of 2D seismic offshore West Greenland. The new data has been compiled into an integrated exploration report including grav mag and seismic data.

The 37000 km regional TGS 2D database offshore West Greenland has revealed a number of sedimentary basins and regional structural highs, - adjacent onshore analogs has revealed that both reservoir, source and seal are present.
