OPL 236

The map shows the geographical regional setting of the Ukana South field, which lies in the south western part of the OPL 236 block, the block covering 1,652 sq.km. 

OPL 236 was part of the original OML 48 which was relinquished by Chevron,  and subsequently awarded to Oando plc, the largest publicly quoted energy company in Nigeria, via a bid round. Seven Energy signed a farm-in agreement with Oando plc in late 2007, whereby Seven Energy is Technical Partner with a 42.75% interest.

The Ukana South gas field was discovered by the Ukana South-1 well in 1988, whilst being operated by Chevron, and was suspended as a gas discovery well. Ukana South gas sands lie between 6000-7000ft. The gas from the field will be sold into the 18" East Horizon pipeline between Port Harcourt to Calabar.

There are eight other prospects in OPL 236 and 3D seismic will be acquired over the south western part of the block in 2009. The Ukana South field will tested for reservoir performance and facilities optimisation in mid-2009, ahead of first gas production in early 2010.
