Tuapse Trough licensed block

Rosneft is carrying out geological exploration works jointly with ExxonMobil at the Tuapse Trough licensed block on the Black Sea shelf, which stretches from the Black Sea coast of Krasnodar Krai. The project operator is OOO RN-Exploration.

The area of the block is 11.2 thousand sq. km with the sea depth ranging from 40 to 2 100 m, and it is considered to be ultra-deep from the standpoint of offshore fields development. During seismic exploration works, 33 prospective structures were discovered at the block. According to independent estimates made by DeGolyer & MacNaughton, the recoverable resources of Tuapse Trough LB amount to 1213,681 million tons.

In August, 2011, Rosneft and ExxonMobil International Company executed an agreement on strategic cooperation that implies joint implementation of projects in the sphere of geological exploration and development of oil and gas fields in Russia and sharing technologies and experience.

In April, 2012, Rosneft and ExxonMobil signed supplementary agreements on project financing and joint operations. Within the framework of implementation of the signed Agreements, in 2011-2012 seismic and gravity-magnetic surveys were performed at the licensed block Tuapse Trough, works relating to interpretation of geological and geophysical data are under way, the plan on preparation to prospecting drilling is being implemented.

In 2013, works related to preparation to the drilling of exploratory wells continued. At the Tuapse licensed block the processing of 4800 sq. km of seismic 3D data was completed, the upper part of the cube of 3D seismic exploration data was performed for 2400 sq. km in order to solve the tasks related to geological engineering surveys, and engineering surveys were performed at three prospective drilling sites.

The ecological monitoring of the environment at Tuapse Trough LB is carried out on an annual basis in strict compliance with the license obligations.
