The new blocks, A3 and A4, are located outboard of Ophir’s existing acreage in the North Gabon basin. Block A3, which will be called the Nkouere PSC, covers an area of 675 km2 and Block A4, which will be called the Nkawa PSC, covers an area of 2,085 km2; both cover water depths of between 2,000m and 2,500m.
Ophir’s analysis of its 2014 North Gabon drill campaign has enhanced the prospectivity of the deepwater distal margin of the North Gabon Basin. In particular the Cretaceous section, where a now-proven oil-prone marine source rock is overlain by a series of deepwater coarse sands. This offers a petroleum system with the potential for large stratigraphic and structural traps. This frontier play is thus far unexplored in the West Atlantic margins and Ophir is now well positioned to chase the play with an expanded footprint comprised of its existing acreage and the new Nkouere and Nkawa PSCs. Ophir is presently acquiring an 8,600 km2 3D seismic programme on the play in its existing blocks and the 3D acquisition will now be enlarged by a further 2,300 km2 to cover these two new blocks.
The Company’s total acreage in Gabon now totals 15,470 km2 across six blocks. Ophir has a 100% participating interest and operatorship in the two new blocks. The Gabonese State has the right to acquire a 20% interest in the newly awarded Nkouere and Nkawa PSCs on commencement of production.
The Gabon National Oil Company also has the right to acquire up to an additional 15% interest at market rates.
