Norwegian multi-client geoscience data provider of exploration and production (E&P)
companies, TGS, has completed its Jaan survey of the Mauritania, Senegal, Gambia, Guinea-
Bissau and Guinea-Conakry (MSGBC) Basin in partnership with PGS and Geopartners.
The survey covers a 28,000Km2 maritime area offshore Senegal, The Gambia and Guinea-

Rune Eng, TGS Executive Vice President Global said, “Recent and significant success in the
MSGBC Basin demonstrates the importance of the province in terms of exploration not only
in Africa, but also worldwide. Learning from these giant discoveries and cross-border
exploration success, the Jaan 3D survey has been specifically designed to highlight key play
fairways and provide a vital exploration volume to enable E&P companies to unlock the next
giant discovery.”

Jaan 3D consists of both newly acquired (over 12,000Km2) and recently reprocessed seismic
surveys, processed and harmonized to create a seamless 3D pre-stack time migration and
pre-stack depth migration volume, which allows explorers to obtain a holistic understanding
of this prolific basin and its unique geological features of the shelf edge trend across

These new results are expected to encourage other countries in the basin to move forward
with licensing rounds and hydrocarbon exploration incentives. Across the MSGBC Basin, this new survey adds to the TGS subsurface data library’s existing 82,000Km of 2D seismic and a further 16,000Km2 of 3D seismic (including newly acquired deepwater The Gambia and Senegal 3D surveys).

In addition to extensive global geophysical and geological data libraries that include multi-
client seismic data, magnetic and gravity data, digital well logs, production data and
directional surveys, TGS also offers advanced processing and imaging services, interpretation
products, and data integration solutions.
