Otto holds a 35 per cent interest in the Edirne Licence onshore Thrace Basin of Western Turkey. The Edirne licence was originally acquired by Otto in 2004 but is now a non operated asset, operated by joint venture partners TransAtlantic, (55%) and a local Turkish company Petraco (10%).

The Turkish Energy Market Regulatory Authority (EMRA) granted the Joint Venture a wholesale gas licence. The Joint Venture is the first to produce and sell onshore Turkish gas directly into the extensive "Botas" gas distribution network, which enables the sale of gas anywhere in Turkey for the best possible price, at a discount to the Botas price.  Gas production and sales commenced in April 2010.

This low cost exploration and development project is teamed with a good fiscal regime and a robust domestic gas price. It is Otto's second producing asset and source of cash flow.
