ConocoPhillips told the market its Coco Marine-1 exploratory well, offshore Cameroon, successfully flowed oil during a drill stem test of a Lower Tertiary reservoir pay interval encountered during drilling.
The well, which was spudded late October, is located in 23m of water in exploration permit PH 77 in Douala Basin, off the coast of Cameroon.
Conoco said the well was drilled to a total depth 2,630 metres and recorded maximum daily flow rates of 3,000 barrels of 34-degree API gravity oil and 1.8 million cubic feet of gas during the test.
"The test marks the first successful flow of liquid hydrocarbons from a Tertiary reservoir in the Douala Basin," the company said.
ConocoPhillips has a 50% stake in the 4,554 sq.km field and is the operator while partner Petronas Carigali holds the remaining 50%. Both companies are currently analyzing well results, and will be working with the National Hydrocarbon Corporation of Cameroon (SNH) on developing forward plans to evaluate the Coco Marine discovery and other identified leads in the permit.
