Aminex Plc has received formal approval from the Tanzanian Minister of Energy and Minerals to extend the work period of the Nyuni Area production sharing agreement (PSA) for a duration of four years. Accordingly, the current work period will now be extended until at least October 2019, Ecofin Agency reported.

This comes as the company began drilling the Ntorya-2 well, located in its Tanzanian Rumuva license, after the Caroil-2 rig was formally accepted on contract. The rig was accepted following inspection by an independent surveyor. Spudding of the Ntorya-2 appraisal well is expected before the end of 2016, informed London South East.

The well is expected to be drilled to an estimated total depth of 2,860m and is targeting the same sandstone channel complex as found at the Ntorya-1, but located further up-dip. The Ntorya-1 discovery flowed gas at 20mcf/d, with 139 barrels of associated condensate, from a 3.5m sandstone interval on test in June 2012.

The Ntorya discovery is situated 20 km from the Mtwara to Dar es Salaam gas pipeline which transports gas from various fields, including the Kiliwani North Field where Solo holds a 7.125% interest, to gas markets, north of Tanzania.
