The Odoptu OP-11 well was drilled to a total measured depth of 40,502ft in terms of ERD and reached a horizontal distance of 37,648ft.
Exxon Neftegas is the operator of the Sakhalin-1 Project on behalf of an international consortium that includes affiliates of the Russian state company Rosneft RN-Astra and Sakhalinmorneftegas-Shelf, Japanese corporation Sodeco and the Indian state oil company ONGC Videsh Ltd.
Odoptu, one of three Sakhalin-1 Project fields, is situated 8km to 11km offshore northeast Sakhalin Island.
Exxon Mobil said that the ERD process enables onshore drilling beneath the seafloor to the offshore oil and gas reservoirs to operate in a safe and environmentally responsible manner in a challenging sub-arctic environment.
Since the first Sakhalin-1 well was drilled in 2003, six ERD wells have been drilled at the project.
