Australian independent ADX Energy, was hoping to spud the Sidi Daher exploration well, onshore Tunisia in February 2011, as of the time of our going to press in late January 2011. The operator of the Chorbane Block signed a Letter of Intent with Challenger Limited for the use of the Rig 37 onshore drilling unit to drill the well. But the spud is subject to completion of civil works and receipt of approvals from the Tunisian authorities.
ADX expects to drill the well to a Total Depth of 2,150metres. The Sidi Daher prospect contains multiple potential reservoir intervals of Tertiary and Cretaceous age that will be evaluated with this well. ADX has estimated prospective resources of 175 billion cubic feet of gas in the Eocene aged Metlaoui Formation and 44 million barrels of oil in the Cretaceous aged Abiod Formation. Additional resource potential exists in the Douleb and Bireno Members of the Cretaceous aged Aleg Formation.
