Valeura Energy has confirmed natural gas discovery in its first exploration well, Bati Gurgen-1, on its 100 per cent owned and operated Banarli Licence in Turkey’s Thrace Basin
The well flowed at an initial rate of 96,277 cu/m of gas per day on a 24-hour production test.
The Canada-listed company also said that preliminary Q4 2015 net petroleum and natural gas sales in Turkey averaged 806 boepd, which was in line with annual guidance and included 124,594 cu/m per day of natural gas at an average price realisation of approximately US$9.9 per 28.3 cu/m and seven bpd of oil and condensate.
The Bati Gurgen-1 exploration well was drilled to a measured depth of 2,735 metres into the top of the Teslimkoy member of the Mezardere formation and was cased to a measured depth of 2,729 metres. Log analysis indicated 32 metres of aggregate net gas pay at an average porosity of 19.6 per cent in multiple stacked sands in the Danismen and Osmancik formations. The well also penetrated several over-pressured, thinner and tighter stacked sands in the Mezardere formation.
The main completion programme consisted of perforating approximately 13 metres of conventional stacked sands in the Osmancik formation below 1,480 metres and carrying out a 24-hour production test.
Over this period, 96,277 cu/m of natural gas, 15 barrels of condensate and minimal water were produced at a stable restricted rate through a 36/64-inch choke. It is expected that the Danismen formation will be completed within one or two months after the well is on production to permit further performance monitoring of the Osmancik formation alone.
The Bati Gurgen-1 well is currently shut-in awaiting completion of the pipeline tie-in to the dehydration facility at the Gurgen-1 well where Valeura Energy holds a 40 per cent working interest located approximately three km to the southeast on the joint venture lands acquired from Thrace Basin Natural Gas (Turkiye) Corporation (TBNG) and Pinnacle Turkey Inc.
