London-listed Oil junion Afren’s Okoro East exploration well, offshore southeast Nigeria has come up trumps having encountered 169m (549ft) true vertical thickness (TVT) of net oil pay and 12.5m (41ft) of net gas pay in excellent quality reservoir sands
The well encountered oil in the Tertiary reservoir sands equivalent to those that have been developed and are in production at the Okoro main field, in addition to the deeper previously unexplored reservoirs.
According to Afren, the discovery of significant pay in the previously unexplored deeper zones opens up further prospectivity at similar levels on the main Okoro Field and elsewhere on Block OML112.
