MOSCOWRosneft and partner Eni have completed drilling of the deepwater exploration and appraisal well Maria-1 on the Zapadno-Chernomorskaya license area in the Russian sector of the Black Sea.

Water depth at the site was 2,109 m (6,919 ft), while the final drilling depth was 5,265 m (17,273 ft).

According to Rosneft, the well discovered a carbonate structure with a 300-m (984-ft) gross interval: this comprises a fractured reservoir which are thought likely to contain hydrocarbons.

The company plans a comprehensive analysis of the geology and the retrieved well samples and to continue exploration and appraisal works on the license area.

Preparations for this initial well on the license included acquiring 4,000 km (2,485 mi) of 2D and more than 3,000 sq km (1,158 sq mi) of 3D seismic, along with other engineering and geological studies.
