Rosneft spins bit under Sea of Okhotsk

May 11, 2016

Russian oil giant Rosneft has started drilling on the Lebedinskoye oil and gas condensate field, which sits under the Sea of Okhotsk, in Sakhalin region, Russia.

It will drill a 5.3km-long, horizontal extend-reach well, drilled from the coast of Sakhalin Island, using drilling contractor RN-Burenie for RN-Sakhalinmorneftegaz, a Rosneft subsidiary. Rosneft says that, during the well construction, latest technologies including real-time reservoir mapping will be used to help ensure optimum entry into formation, aid decision-making about well bore trajectory adjustment, and refine the field development program.

As part of the project, three horizontal production wells with the length of 5000-7000m are to be drilled.

The first oil from the field flowed in 2014. 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.

The Lebedinskaya offshore structure is 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, in 2014.

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