According to the company, the Hajdunanas-2 appraisal was drilled in the Hernad licences which cover a total of 5,420sqkm in north eastern Hungary. JKX holds a 50% interest in the licenses. Exploration well results are expected in 2009 from the drilling of other prospects on both the Hernad licenses.
The Hajdunanas-2 well was drilled vertically to a total depth of 1,467m and encountered several gas-bearing intervals within the Miocene Pannonian interval between 990m and 1,080m.
The company said that, the productive Miocene volcanoclastic sequence encountered in Hajdunanas-1 below the Pannonian interval was found to be tight at this location and, consequently, a deeper Miocene target was not pursued.
Two production tests were completed in the Pannonian sands. An upper zone with a 25m perforated interval flowed at 7.4 million cubic feet per day (MMcfd) of gas through a 14mm choke, with flowing wellhead pressure of 1,250psi. The lower zone tested a 5m interval and flowed at 8.5MMcfd through a 16mm choke, with a flowing wellhead pressure of 1,308psi.
JKX Oil & Gas is an exploration and production company which has licence interests in Ukraine, Russia, Georgia, Bulgaria, Turkey, Hungary, Slovakia and the United States.
