Block 6 Muni River Ultra-deep waters Exploration Galp 45% (op.) | KE 25% | Shell 20% | ANP 10%
Block 11 Muni River Ultra-deep waters Exploration Galp 20% | KE 35% (op.) | Shell 30% | ANP 15%

Galp drills the first exploratory well in the country in block 6. Although this specific prospect does not show potential for future evaluation, the drilling proved the existence of an active petroleum system and made it possible to collect a significant amount of data that will guide the definition of the next exploratory steps in the region.

Galp assumes the role of operator in block 12, replacing the previous operator Kosmos Energy.

In block 6, preparatory work is being finalised for the drilling of the exploratory well called Jaca.

Galp decides to abandon block 5, where it has been present since 2016.

Geological and geophysical studies continue to progress, particularly in block 6, where a prospect has been identified for the drilling of an exploration well.

Processing and interpretation of 3D seismic data collected in 2017. Geological and geophysical studies to assess the initial prospectivity of the blocks.

3D seismic acquisition campaign of 16,000 km2 along blocks 5, 6, 11 and 12.

Galp strengthens its presence in São Tomé and Príncipe with the acquisition of a 20% stake in blocks 5, 11 and 12, adjacent to block 6 already operated by the company.

Galp has been present in São Tomé and Príncipe since 2015, when it acquired a 45% stake and the operation of block 6.

Block 6 is located in São Tomé and Príncipe's Exclusive Economic Zone, in a basin that is little explored but has high potential due to its proximity to areas with a proven oil system.
