Maputo, Mozambique — ESI-AFRICA.COM — 01 November 2011 – The Italian energy company ENI has announced that its natural gas discovery in the Rovuma Basin, off the coast of the northern Mozambican province of Cabo Delgado, is considerably larger than its original estimates

On 20 October, the company issued a statement here that its exploratory well, ‘Mamba South 1’, drilling in water 1,585m deep in offshore Area 4 of the Rovuma Basin, had discovered 212m of continuous gas pay, giving an estimate of at least 15 trillion cubic feet of gas.

ENI continued to drill deeper and found what it described as “a new separated pool that contains a potential of up to 7.5 trillion cubic feet of gas in clean sands from the Eocene age.”

These two discoveries in one well indicate total gas reserves here of at least 22.5 trillion cubic feet, reports all-Africa.com, citing the Mozambique News Agency AIM.

ENI is continuing to drill at Mamba South 1 until it reaches a total depth of 5,000m, after which it will move the rig 22km to the north and drill a second well, to be known as Mamba North 1.

The company announced last week that it had already made a start with the front-end activities for timely marketing of the gas both internationally and locally.

ENI is the operator of area 4, with a 70% participating interest. Its partners are the Portuguese company Galp Energia (10%), the Korea Gas Corporation (KOGAS – 10%), and Mozambique’s publicly owned National Hydrocarbon Company, ENH (also with 10%).

The ENI announcements mean that from just one well the Italian company has discovered more than twice the amount of natural gas found by the US-based company Anadarko. The four wells sunk by Anadarko in Rovuma Basin Area 1 hit an estimated 10 trillion cubic feet of recoverable gas.
