Bulgarian tiebacks nearing completion
Melrose Resources is preparing to bring onstream two new gas field developments in the Bulgarian sector of the Black Sea.
EDINBURGH, UK -- Melrose Resources is preparing to bring onstream two new gas field developments in the Bulgarian sector of the Black Sea.
Kavarna and Kaliakra both are being developed as single well subsea tiebacks to the Melrose operated Galata field platform. GSP Offshore’sBigfoot pipelay barge should arrive on location shortly to install the two flow lines.
First production from Kavarna is due in September with Kaliakra set to follow in October. Combined output from the two fields will be around 45 MMcf/d.
Recently, Melrose discovered further quantities of gas with its Kavarna East No.1 well, testing a Palaeocene prospect in between Kavarna and Kaliakra. Analysis indicates reserves of 12 Bcf, which will likely be produced via a low cost tieback next year to the Kavarna subsea well location.
The Kavarna East reservoir structure appears to be filled with gas to the spill point, in line with other fields discovered on the same geological trend. According to Melrose, this substantiates the prognosis of a large regional biogenic gas source, with the likelihood that further gas volumes have migrated north into the central area of the Galata block.
The company plans to acquire seismic over this area in 2011 to assess its prospectivity. It is also lining up a well on the Kaliakra East structure, which has prospective resources of 59 Bcf.
