Present in São Tomé and Príncipe since 2015, Galp acquired a 45% stake in Block 6, where it is the operator. In 2016, Galp expanded its presence with the acquisition of a 20% stake in blocks 5, 11 and 12. During 2019, Galp has decided to withdrawn from block 5.
In 2017, a 3D seismic acquisition campaign was initiated, covering an area of 16 thousand km2 along all blocks.
Following the geological and geophysical studies carried out on block 6, Galp and the other partners are finalising the preparation of the first exploratory well on the block. The well, known as Jaca, is expected to be spud in late 2021 / early 2022.
Galp assumed the role of operator for block 12 in 2020, replacing the previous operator, Kosmos Energy. Kosmos' stake was distributed in proportion to the stakes of the other members of the consortium.
