The Sovereign Explorer semisub, provided by Transocean, is drilling well 1-MRK-2-SPS. It is expected to take approximately three months to reach all five of the mapped targets.

“Interpretation of the 3D data for BM-S-29, combined with recently announced discovery at a distance of 18km from the block, has confirmed our view of the substantial potential of BM-S-29. We are confident that this is a promising exploration area, and pleased to have initiated the drilling of our first offshore well,” commented Paulo Mendonça, OGX’s general executive officer.
