São Tomé and Príncipe's national petroleum agency ANP-STP has held a public consultation on the Environmental, Social and Health Impact Assessment for a planned 3D seismic survey in Block 4 of the country's Exclusive Economic Zone. The consultation took place on 6 February in the Autonomous Region of Príncipe, marking a formal procedural step before seismic acquisition work can proceed.
Block 4 is operated by Shell, in a consortium that also includes Petrobras, Galp, and ANP-STP itself. The public consultation is a regulatory requirement under the ESIA process, and its completion moves the block one step closer to active seismic data acquisition. Government officials attended the meeting, signalling institutional engagement with the process.
The ESIA consultation represents an early-stage exploration milestone — not a contract award, block grant, or final investment decision. No seismic acquisition contract has been announced, and no timeline for the survey itself has been disclosed in the available information. The consortium composition nonetheless reflects significant international operator interest in São Tomé and Príncipe's offshore acreage, with two major integrated oil companies and a major Portuguese independent holding positions alongside the national agency.
São Tomé and Príncipe sits in the Gulf of Guinea, a region that has attracted sustained interest from Norwegian service companies due to its geological proximity to producing basins in Nigeria, Equatorial Guinea, and Gabon. While the archipelago's acreage remains at an early exploration stage, the involvement of operators of Shell and Petrobras's scale suggests the programme is being pursued with material resources and technical seriousness. Successful 3D seismic acquisition would generate the subsurface dataset needed to evaluate whether the block warrants drilling, making this consultation a foundational step in a potentially multi-year exploration sequence.
For Norwegian service and technology companies, the immediate actionable window is narrow: no tender, contract, or equipment procurement process has been announced. However, the confirmed operator identity and consortium structure provide a clear set of relationship targets. Shell and Petrobras both maintain established procurement relationships with Norwegian subsea, survey, and well-services suppliers, and early positioning ahead of any seismic vessel tender or future drilling campaign is advisable.
