Angola: Sonangol declares Cobalt gas find commercial

Sonangol has declared Cobalt Energy International’s Zalophus-1 well on Block 20 to be a commercial gas discovery. Sonangol said in a statement the Kwanza Basin well was drilled to a depth of 5,210 metres in 1,830 metres of water and encountered a 44-metre hydrocarbon column in the pre-salt. It estimated resources at 2.8tcf of gas, as well as liquids. A deal announced in August 2015 for Cobalt to sell blocks 20 and 21 to Sonangol for $1.75bn has yet to be finalised.
