HOUSTON, Jan. 28 --
Exxon Neftegas Ltd., operator of the Sakhalin-1 project, drilled the world’s longest extended-reach well at Odoptu field, off Far East Russia, ExxonMobil Corp. said.

The Odoptu OP-11 well reached a measured total depth of 40,502 ft and a horizontal displacement of 37,648 ft. Exxon Neftegas completed the well in 60 days.

Odoptu, one of three Sakhalin-1 Project fields, is 5-7 miles off northeast Sakhalin Island.

ExxonMobil said the project involves “one of the most challenging sub-arctic environments in the world.”

The first Sakhalin well was drilled in 2003, and the project has drilled six of the world’s 10 record extended-reach wells. The specially designed Yastreb rig has been used throughout.

Since startup, the Sakhalin-1 project has produced 300 million bbl of oil for export to world markets. It also has supplied 235 bcf of associated natural gas locally.

Sakhalin-1 includes Chayvo, Odoptu, and Arkutun Dagi oil and gas fields. Potential recoverable resources are 2.3 billion bbl of oil and 17.1 tcf of gas.
