Exclusive: Rosneft, Eni make no commercial discovery at Black Sea well: source

MOSCOW (Reuters) - Russian state oil company Rosneft and Italy's Eni did not make a commercial hydrocarbon discovery in the Black Sea as the well they were drilling proved to be dry, a source close to operations told Reuters on Wednesday.

Rosneft and Eni started to drill the well, known as "Maria-1", in December.

The ultra-deep-water prospecting and appraisal well was being drilled using the Scarabeo-9 rig and Rosneft said this week it had a target depth of 6,126 metres.

Eni declined to comment. Rosneft did not reply to a Reuters request for immediate comment.
