Rosneft and Lukoil began the construction of prospecting and appraisal well № 1 at Ribachya structure as part of geologic exploration of North Caspian licensed site, situated in a Russian sector of North Caspian water area.
The project is operated by the Caspian Oil Company. The planned drilling depth is 1650 meters. The aim of well drilling is to explore the geologic structure and to detect oil and gas deposits, as well as to evaluate their commercial significance.
