MILAN -- Eni has started production from the gas platform Annamaria B in the Adriatic Sea .C11.AG concession. Current output is around 800,000 cu m/d, but will reach about 1.2 MMcm/d at full operation.
The Annamaria field straddles the median line between Italy and Croatia, 60 km (37 mi) from the Italian east coast in a water depth of around 60 m (197 ft). It is the first cross-border field to be put into production in the Adriatic. The governments of the two countries approved the unitization and joint development agreement last July.
Annamaria A, a “twin” platform already operating in Croatian waters, produces at a similar rate to Annamaria B’s current level. This facility is operated by the INA/Eni joint venture InAgip.
Gas is sent through a subsea pipeline to the treatment plant at Fano, 70 km (43.5 mi) away, for onward passage into the national distribution network.
Eni estimates remaining reserves and gas produced to date at around 10 bcm, or 64 MMboe. It describes Annamaria as its most significant new development in the region since 1998, with a total cost of around $561 million.
Construction was performed by Rosetti Marino, Saipem Energy Services and Intermare Sarda in Italy at the yards Marina di Ravenna and Arbatax (Sardinia) yards; and the Rijeka yard in Croatia.
