Perenco says that the Sputnik-1 well, targeting a pre-salt structure in Gabon's offshore Arouwe block, has encountered non commercial hydrocarbon pay in up to 300 metres of net sandstone reservoir.
The Vantage Tungsten Explorer drill ship, drilled Sputnik-1 to a final depth of 4,868 metres in water depths of 1,023 metres.
The rig will now leave the Arouwe block and the results of this well will be incorporated into wider understanding of the region."
Tullow has a 35% interest in the Arouwe block with partners Perenco (35%, Operator) and ExxonMobil (30%).
Commenting on today's announcement, Angus McCoss, Exploration Director, said, "This is an encouraging result from the pre-salt play, offshore Gabon. Having found a petroleum system, we will now take the data from this well and integrate it with our seismic data to discuss with partners our next steps for the licence."
