Gabon: Sputnik pre-salt well is non-commercial

Operator Perenco has announced that the Sputnik-1 well, targeting a pre-salt structure in the offshore Arouwe Block, has encountered non-commercial hydrocarbon pay in up to 300 metres of net sandstone reservoir. The Vantage Tungsten Explorer drillship drilled Sputnik-1 to a final depth of 4,868 metres in water depths of 1,023 metres. The rig will now leave the block, and the results of this well will be incorporated into wider understanding of the region, Perenco said.
