LONDON -- In late October 2008, Melrose Resources made a gas discovery with the Kavarna No.1 exploration well in the Black Sea, offshore Bulgaria. The well encountered a well developed, gas bearing Paleocene reservoir formation with an initial reserve estimate of 24 bcf. Prior to running open-hole logs a strong gas influx occurred in the wellbore. The company proceeded to plug and re-drill the well.
The replacement well, Kavarna No. 2, has been drilled and encountered 125 ft (38 m) of net gas pay with an average porosity of 27%. The new well data has confirmed the initial reserves estimate, the company reports.
The well is currently being completed with a subsea tree allowing for a tie back to the Galata field facilities. The company anticipates first production in 3Q 2009. The Kaliakra discovery, which contains estimated reserves of 47 bcf, is scheduled to be tied back to the Galata facilities for first production in 2010.
