Senegal’s state-owned hydrocarbons company Petrosen has officially launched the country’s first offshore licence round.

The licensing round comprises 12 blocks in the Mauritania-SeneGambia-Bissau-Conakry (MSGBC) Basin off Senegal.

According to TGS, the MSGBC Basin is home to high-profile oil and gas discoveries, both on and off the shelf.

Bids can be submitted in the next six months, with final applications delivered to the Senegal Ministry of Petroleum and Energy by July this year.

Petrosen has partnered with TGS, GeoPartners and PGS to provide over 14,000km of 2D data and over 10,000km² of 3D data.

It will also provide more than 50,000km² of Multibeam data with shallow cores and geochemistry to interested parties in the offshore licensing round.

Furthermore, TGS acquired additional 3D seismic data to offer interested bidders an improved subsurface understanding ahead of bid submissions.

TGS Southern Hemisphere executive vice-president Rune Eng said: “The launch of Senegal’s landmark license round is a seminal moment in the nation’s hydrocarbon history.

“TGS is delighted to be able to support this initiative with a full complement of regional data sets that should help E&P companies to de-risk their exploration activities as they seek to take advantage of a world-renowned oil and gas basin.”

TGS’ Senegal North Ultra-Deep Offshore (SN-UDO-19) 3D survey is the latest one covering over 5,100km².

It is designed to illuminate plays in the ultra-deep, allowing explorers to build upon the success the basin has experienced with the Sangomar field, the GTA complex and Yakaar discoveries.

The SN-UDO-19 survey is mostly complete, with fast track data anticipated in the second quarter of this year and full data by the fourth quarter.
