"The approval effectively commences the development of the Kavarna field, which contains estimated reserves of 24 Bcf (billion cubic feet of gas) and is located 8 kilometres east of Melrose's Galata field platform," the company said in a statement.
The company expects the field to be on stream by July 1, 2010.
Melrose has also also filed an application before the government in Sofia to develop a nearby gas field - the Kaliakra field which contains 57 Bcf of reserves. The gas field is located 14 kilometres east of Galata gas field which the company plans to transform into a gas storage depot together with state-run gas monopoly Bulgargaz.
First gas from the Kaliakra field is expected by October 1, 2010.
The total capital expenditure for the two developments is expected to be $59 million (39.6 million euro), Melrose added.
Melrose Resources (www.melroseresources.com) drills also in neighbouring Romania and in the U.S., Eqypt, France and Turkey.
