Melrose Resources said gas samples obtained from its Kaliakra No.2 well in Bulgaria confirmed that the reservoir has very good properties, with an average porosity in excess of 30% high gas productivity.Given the quality of the reservoir, it was not necessary to run flow tests in the well and it has been temporarily suspended for future use as a development well, the group added. 'We are very pleased with the results from the Kaliakra appraisal well which confirm our geologic model for the area and effectively increases the most likely combined reserves estimate for Kavarna, Kavarna East and Kaliakra to 100 Bcf,' said chief executive David Thomas.'Beyond these three structures we still have two other exploration prospects to drill on the same geologic trend and we plan to acquire further 3D seismic data in early 2010 to the north of the trend where we believe the same Palaeocene exploration play may be present.'
