The wells Nzanza-1 and Cinguvu-1 are located around 350km northwest of Luanda in a water depth of some 1.400mt. During production test, the Nzanza-1 well produced oil with a density of 18 API gravity at rates above 1,600 barrels per day. At Cinguvu-1, the production test reached a maximum flow of 6,400 barrels per day of oil with a density of 23 API gravity.
