The delineation was through the Agulha 2 well drilled in a water depth of 2,603 m (8,540 ft) to a TD of 5,645 m (18,520 ft). The well is located in the southern part of the Area 4 block, 12 km (7 mi) south of the Agulha 1 discovery well and 80 km (50 mi) off the Cabo Delgado coast.
Agulha 2, the 12th well successfully drilled in Area 4, proved about 25 m (82 ft) of gas column in good-quality Paleocene reservoir sandstones and confirmed the southern extension of the field.
Eni is considering further exploration drilling in the southern part of Area 4. Total resources in the area are estimated at 85 tcf of gas in place.
Eni is the operator of Area 4 with a 50% indirect interest owned through Eni East Africa, which holds 70% of Area 4. The other partners are GalpEnergia (10%), KOGAS (10%), and ENH (10%, carried through the exploration phase). CNPC owns a 20% indirect participation in Area 4 through Eni East Africa.
