The summer exploration and drilling season in the Barents Sea is well under way, with Eni and Gazprom both now active in the region.

DOF Subsea is currently towing the Goliat Platform the 85 kilometres from its mooring at Hammerfest, northern Norway, to the Goliat field in the Norwegian Barents Sea. Once the 15-hour journey is complete, DOF Subsea will connect the cylindrical FPSO to 14 preinstalled anchor lines and to its power supply, which is being delivered by one of the world’s longest submarine cables. Risers will be installed and topside and subsea systems made ready before DOF hands the rig over to the operator, Eni Norge. Once it starts production, Goliat will become the world’s northern-most offshore production rig.

Meanwhile, Gazprom has begun a 3D seismic survey in the Russian sector of the Barents Sea. The Vyacheslav Tikhonov seismic research vessel is performing the study over a 3,200 kilometre-square area in the Ludlovskoye licence block.

Gazprom says that geophysical studies conducted during the Soviet era identified potential gas deposit structures on the Artic Shelf. As of January 2012, the Ludlovskoye gas field was registered as having 80.1 billion cubic metres of C1 gas reserves and 131 bcm of C2 gas reserves.

Alexey Davydov, Managing Director of Gazprom Geologorazvedka, said, ‘Modern technology and seismic monitoring, such as the 3D survey, are being used by Gazprom on this site for the first time.’ The data acquired will enable the company to estimate reserves and assess the potential environmental impact of proposed exploration drilling.
