Sakhalin-1 project drills world’s longest extended reach well

Exxon Mobil Corporation announced today that its subsidiary, Exxon Neftegas Limited, has successfully drilled the world’s longest extended-reach well at the Odoptu field, offshore far east Russia. Exxon Neftegas is the operator of the Sakhalin-1 project on behalf of an international consortium that includes affiliates of Rosneft RN-Astra and Sakhalinmorneftegaz-Shelf; SODECO; and ONGC Videsh Ltd.

The Odoptu OP-11 well reached a total measured depth of 40,502 ft (7.67 miles) to set a world record for extended-reach drilling (ERD). The Odoptu OP-11 also set a world record with a horizontal reach of 37,648 ft (7.13 miles).

“ExxonMobil, through Exxon Neftegas Limited, continues to successfully develop and operate the Sakhalin-1 oil and gas project to maximise economic recovery of this world-class resource,” said Neil Duffin, President, ExxonMobil Development Company.

Odoptu, one of three Sakhalin-1 project fields, is situated 5 - 7 miles offshore northeast Sakhalin Island. The ERD process enables onshore drilling beneath the seafloor to the offshore oil and gas reservoirs to successfully operate in a safe and environmentally responsible manner in one of the most challenging sub-arctic environments in the world.

Since startup, the Sakhalin-1 project has produced approximately 300 million barrels of oil for export to world markets. It also has been a key supplier of approximately 235 billion ft³ of associated natural gas to customers in Khabarovsk Krai, in far eastern Russia, to heat homes and meet growing energy needs.
