Tuapse Trough

The Tuapse licensed block is located on the Russian Black Sea shelf, stretching along the Black Sea coast of the Krasnodar region. The block covers an area of 11,200 sq. km, with the sea depth varying from 1,000 to 2,000 meters. Exploration activities have revealed approximately 70 prospective structures within this ultra-deep block.

An exploration license to the Tuapse block was obtained by Rosneft in August 2003. The Company holds a 100% stake in the Tuapse Trough project. As of year-end 2008, Rosneft shot 2,100 liner km of 2D seismic and 1,030 sq. km of 3D seismic at the Tuapse licensed block.

Within the project, shooting of 406 square km of 3D seismic was completed in 2008, as was the processing and interpretation of materials for target strata and for upper layers (to reduce drilling risks). Three-dimensional basin modeling was also completed, and locations were chosen for prospecting wells.
