The water depth at the drilling site reaches 2109 meters. The actual well depth is 5265 meters. A unique carbonate structure with 300 meters gross interval was discovered on drilling this well.

This structure constitutes a fractured reservoir that is highly likely to contain hydrocarbons. These results instill confidence in the possibility to discover large oil and gas fields in the Russian Black Sea waters. The company plans to conduct a thorough geological processing of the materials and to continue exploration and appraisal works on the license areas.
