SAN DONATO MILANESE, Italy – Eni has notched two more giant gas discoveries in the Mamba complex in Area 4 offshore Mozambique.
The Mamba South 2 and Coral 2 delineation wells have added 6 tcf (170 bcm) to the Area 4 reserves base, now estimated to hold 23 tcf (651 bcm)-plus in place, with potential of 75 tcf (2.1 tcm) throughout theMamba complex.
Mamba South 2 was drilled in 1,918 m (6,293 ft) of water to a TD of 4,300 m (14,107 ft), 9 km (6 mi) east ofMamba South 1 and 50 km (31 mi) from the Capo Delgado coast.
It intersected 60 m (197 ft) of gas pay in good quality Oligocene reservoirs. The well also proved hydraulic communication with the same reservoir at Mamba South 1. On test it flowed lean gas at a sustained rate of 140 MMcf/d (4 MMcm/d).
Coral 2 was drilled in 1,950 m (6,398 ft) of water to a TD of 4,725 m (15,502 ft), 15 km (9.3 mi) northwest of Coral 1, 50 km off the Capo Delgado coast. It encountered 140 m (459 ft) of gas pay in good quality Eocene reservoirs, also confirming hydraulic communication with the same reservoir of Coral 1.
Eni plans a production test of Coral 2, and to drill at least two more back-to-back delineation wells, Coral 3 and Mamba South 3, to assess the full potential of the Mamba complex.
