Rosneft commenced operational drilling at the Lebedinskoye oil and gas condensate field in the Sea of Okotsk. It will drill a 5.3 km long horizontal extend-reach well under the bottom of the Sea of Okhotsk.

Drilling operations are carried out by the drilling contractor RN-Burenie for RN-Sakhalinmorneftegaz, a Rosneft subsidiary. During the well construction latest technologies will be used. In particular, the real-time reservoir mapping technology will help ensure optimum entry into formation, make prompt decisions about well bore trajectory adjustment, and refine field development program.

As part of the project total of three horizontal production wells with the length of 5, 000 to 7, 000 m are to be drilled. The first oil from the new wells is expected in the current year. The infrastructure of RN-Sakhalinmorneftegaz will be used in the development of the field.

Note for editors:

Lebedinskaya offshore structure is located on the North-Eastern Shelf of the Sea of Okhotsk, Okhinsky District, Sakhalin Region.

Two prospecting and appraisal wells were previously drilled at the field; one of the wells was put on pilot production.

The quality of crude from the Lebedinskoye field is close to that of Sokol grade.
