Oil and gas survey consultants Fugro United Kingdom will process the data, which is expected to be ready for interpretation in early December.

Otto told the market this morning that the 149-square kilometre survey was finished under budget and two weeks ahead of schedule, with no interruptions.

“Our Turkish Operator has done an excellent job of managing the seismic acquisition and we are pleased that the survey has been completed ahead of schedule,” Otto chief executive Alex Parks said.

“We are looking forward to the drilling campaign scheduled to commence in December 2007 and are confident the joint venture has sufficient gas reserves in Turkey to warrant an immediate gas development feasibility study, aiming at commencing production in 2008.”

The survey was designed to cover the central, and so far most prospective, section of the permit which includes the joint venture’s three gas discoveries: Koyustu-1, Bati Umur-1 and Arpaci-1

The Edirne Licence joint venture comprises: Merty Energy (joint operator -10%),

Petrako (joint operator - 10%), Otto Energy (35%) and Incremental Petroleum (45%).
