The round will be open for six months from October 2017, with awards expected by October 2018. Companies will be able to submit bids on all open blocks.

“This is an exciting time for The Republic of Guinea. The recent successes in the Northern MSGBC Basin have increased the industry interest in this relatively under explored region, and this chain of success will steadily and inevitably flow down south to us. We currently have an active rig in our waters, drilling what we hope will be the first of many commercial successes,” commented Diakaria Koulibaly, CEO of ONAP.

TGS has ~14,000 km of modern, high quality 2D data coverage over the blocks on offer. Click here to learn more.
