Afren keen to develop offshore Nigeria Okoro oil field

Offshore staff

LONDON – Afren has completed testing at its Okoro East oil discovery offshore southeast Nigeria.

Results of three subsequent DSTs have confirmed a good quality 38-40º API crude. Pressure data supports the pre-drill volumetric estimates of a Pmean stock oil in place of 157 MMbbl. Future horizontal production wells on the structure should be capable of delivering 4,500-7,000 b/d per well.

Afren plans to drill two producer wells in the second half of this year using spare slots on the existing Okoro platform. These wells will be tied back to the Armada Perkasa FPSO during the second half of 2012.

Up to eight production wells could be drilled under a full, possibly standalone, field development scenario.

Okoro East is 2 km (1.2 mi) east of the Okoro main field.  It is in a similar structural setting with a fault sealed three-way dip closure in Tertiary reservoir sands at equivalent intervals to the main Okoro field.
