Afren-logoNigerian player Optimum Petroleum, along with drilling partners Afren and Lekoil, struck a “significant light oil accumulation” at the Ogo-1 well on the Ogo prospect in OPL 310 off Nigeria.

The well was drilled to 3205 metres and threw up a gross hydrocarbons column of 160 metres with 66 metres of net stacked pay.

Drilling it set to continue a little deeper, however, as the partners chase further high potential zones.

Optimum was targeting 78 million barrels of of oil equivalent of potential resource in its initial target. However, Afren wrote in a statement on Wednesday: “Based on evidence to date, targeted resources are likely to be significantly in excess of previous estimates.”

Afren continued: “The Ogo-1 discovery, testing a four-way dip-closed structure in the Turonian, Cenomanian, and Albian sandstone reservoirs, confirms the extension of the same Cretaceous sandstones that have yielded other significant discoveries along the West African transform margin.”

The Ogo-1 probe spudded on 23 April. A sidetrack will also be drilled, aiming for a separate structure with a resource potential of about 124 million boe.

The current well is being drilled by GSF Transocean Monitor and lies due east of Yinka Folawiyo’s Aje asset.

Participating interest in the block are Optimum on 60%, Afren on 22.86% and Lekoil on 17.14%. Economic interest is Optimum on 30%, Afren on 40% and Lekoil on 30%.
