IRVING, Texas -- ExxonNeftegas has completed drilling the first two extended-reach wells at the Odoptu field offshore Sakhalin Island. The company operates it on behalf of the five-company Sakhalin-1 Consortium.

The land-rig Yastreb, based at a location onshore Sakhalin, drilled horizontally under the Sea of Okhotsk to a target area over 9 km (5.6 mi) offshore in the Odoptu oil reservoir. The extended-reach wells are the first of seven designed to tap the reservoir. Production should start during the second half of 2010.

Neil Duffin, president of ExxonMobil Development Co. said: “The project has applied industry-leading technology to successfully operate in a safe and environmentally responsible manner in one of the most challenging sub-arctic environments in the world, while providing important economic benefits to Russia.”

ExxonMobil says its Fast Drill technology has optimized performance at Odoptu, paving the way for lower development costs. Other activities for this project include the construction of a new onshore oil and gas treatment plant and installation of a flowline to the existing Chayvo onshore processing facility.

The Sakhalin-1 Project encompasses the phased development of the Chayvo, Odoptu, and Arkuntun-Dagi fields, which have combined resources estimated at 2.3 Bbbl (307 million tons) of oil and 17 tcf (485 bcm) of natural gas. The Chayvo field, the project’s initial development, started production in 2006.

Since startup, Sakhalin-1 has delivered over 240 MMbbl (32 million tons) of oil for export to world markets, and nearly 180 bcf (over 5 bcm) of associated gas to the Khabarovsk Krai region in eastern Russia.

The Sakhalin-1 consortium includes ENL (30%); Sakhalin Oil and Gas Development Co. (30%); affiliates of Rosneft, the Russian state-owned oil company, RN-Astra (8.5%); Sakhalinmorneftegas-Shelf (11.5%); and ONGC Videsh (20%).
