The document discusses TGS's extensive 2D seismic data library offshore Vietnam, including the Baldur Regional 2D seismic survey which covers over 14,400 km and provides regional coverage of Vietnam's offshore area. It also mentions the Baldur South and North surveys which together cover various basins and geological features in the region. Finally, it notes that the surveys enhance understanding of geology, basin architecture, and petroleum systems through improved well ties.

MULTI-CLIENT 2D SEISMIC LIBRARY
TGS maintains an extensive multi-client geoscience data library offshore Vietnam.
The Vietnam Regional 2D seismic survey (BR08) is a regional well-tie survey offshore Vietnam which provides a regional grid of data
over the whole of Vietnam’s offshore area. The survey, currently comprising over 14,400 km of modern long-offset data, is processed
in both time and depth.
The Baldur South survey covers the Cuu Long, Nam Con Son Basins and margins of the Malay Tho Chu, West and East Natuna, West
and North Luconia and the East Vietnam / South China Sea Basins. In addition, the data covers the Con Son Swell, Khorat Swell and
Toy Hua Shear Zone. The Baldur North survey is tied to the southern data through the Phu Khanh Basin and covers the southern Song
Hong Basin (Central and South East Yinggehai – Song Hong).
