After testing confirmed a high quality oil find at the project, the company said it expected future horizontal production at the Okoro East wells would yield between 4500 barrels and 7000 of oil per day per well, based on data from three drill stem tests undertaken since January 17.
According to the tests, the oil reserves is of between 38 degrees API and 40 degrees API.
Afren said the wells would be drilled in the second half of this year using the free well head slots on the existing Okoro platform.
They would be tied back to the Armada Perkasa floating production, storage and offloading vessel, a move Afren chief executive Osman Shahenshah said would ensure a high return.
“The well has also opened up follow on prospectivity on the block that we will continue to evaluate,” he said.
Afren and its partner in development licence OML-212, Amni International Petroleum Development Company, would now consider development options for the project, he said.
Up to eight production wells would be drilled there under a full field development scenario.
The well was spudded in December by the Transocean jack-up Adriatic IX, which the company used to search for oil near its producing Okoro field.
