«The physics based modeling and experimental validations of our IHQ technology allowed us to successfully design and drill the Z-11,» said Steve Cassiani, president of ExxonMobil Upstream Research Company. «With this technology we were able to take into account a broad range of interdependent design variables including rock strengths, stresses, and wellbore hydraulics to successfully drill this well.»

Odoptu, one of three Sakhalin-1 Project fields, is situated 5 to 7 miles (8 to 11 kilometers) 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.

Exxon Neftegas Limited (30 percent interest) is operator for the project, which includes the Japanese company Sakhalin Oil and Gas Development Co. Ltd., (30 percent); affiliates of Rosneft, the Russian state-owned oil company, RN-Astra (8.5 percent), Sakhalinmorneftegas-Shelf (11.5 percent); and the Indian state-owned oil company ONGC Videsh Ltd. (20 percent).

More information on the Sakhalin-1 Project can be found on http://www.sakhalin1.com.

The Sakhalin-1 Project will bring significant economic benefits to Russia including over US$50 billion in direct revenues to the Russian state, major infrastructure improvements, technology transfer and the supply of natural gas to customers in the Khabarovsk Krai in the Russian Far East. Notably, over 80 percent of the Sakhalin-1 Project drilling rig operators are Russian nationals and project contract awards to Russian companies have reached approximately US$3.8 billion.

Since startup, the Sakhalin-1 project has produced approximately 300 million barrels (39 million tons) of oil for export to world markets. It also has been a key supplier of approximately 235 billion cubic feet (6.8 billion cubic meters) of associated natural gas to customers in Khabarovsk Krai, in far eastern Russia, to heat homes and meet growing energy needs. The project will continue to help meet future natural gas demand in this region.

Exxon Mobil Corporation (NYSE:XOM) announced today that its subsidiary, Exxon Neftegas Limited (ENL), has completed drilling of the Z-11 well, the longest measured depth extended-reach drilling (ERD) well in the world. Located on Sakhalin Island offshore Eastern Russia, the record-setting Z-11 achieved a total measured depth of 37,016 feet (11,282 meters) or over seven miles.

Note to Editors

Since the first Sakhalin-1 well was drilled in 2003, the time required to drill these world-class wells has been reduced by more than fifty percent. When compared to industry benchmarks, Sakhalin-1 wells are the world’s fastest drilled ERD wells.

CAUTIONARY STATEMENT: Estimates, expectations, and business plans in this release are forward-looking statements. Actual future results, including production rates; cost efficiencies; project plans, schedules, costs, and results; and commercial arrangements could differ materially due to changes in long-term oil and gas price levels or other market conditions affecting the oil and gas industry; political or regulatory developments; reservoir performance; technical or operating factors; the outcome of negotiations; and other factors discussed under the heading «Factors Affecting Future Results» included in Item 1A of ExxonMobil’s most recent Form 10-K and posted on our website (www.exxonmobil.com).

Sakhalin-1 includes the Chayvo, Odoptu, and Arkutun Dagi oil and gas fields located off the northeast coast of Sakhalin Island in the Russian Far East. Potential recoverable resources are 2.3 billion barrels (307 million tons) of oil and 17.1 trillion cubic feet (485 billion cubic meters) of natural gas.

The multiphase Sakhalin-1 Project includes the Chayvo field which is located 5 to 7 miles (8 to 11 kilometers) offshore. The Z-11 was drilled to the Chayvo reservoir from the Yastreb rig, the world’s largest land-based drilling rig. Overall, the Chayvo field reached its peak production rate of 250,000 barrels (34,000 metric tons) per day in February 2007 after an on-schedule startup in October 2005. The Z-11 is the 17th ERD producing well to be completed as part of the Sakhalin-1 Project. It was drilled in 61 days, more than 15 days ahead of schedule and below expected cost with no safety or environmental incidents.

CAUTIONARY STATEMENT: Statements in this release regarding future events and conditions are forward-looking statements. Actual future results, including project plans and schedules and resource recoveries, could differ materially due to changes in long-term oil and gas price levels or other market conditions affecting the oil and gas industry; political or regulatory developments; timely completion of development plans; reservoir performance; technical or operating factors; the outcome of commercial negotiations; and other factors discussed under the heading «Factors Affecting Future Results» posted in the «Investors» section of our website (www.exxonmobil.com).

«ExxonMobil, through the operatorship of Exxon Neftegas Limited, is pleased that the Sakhalin-1 Consortium achieved this record-setting milestone,» said Neil Duffin, president of ExxonMobil Development Company. «Our consortium is committed to the continuing development of the Sakhalin-1 Project which will require significant investment, planning, execution, operating expertise and the employment of leading-edge technology.»

IRVING, Texas—(BUSINESS WIRE)— Exxon Mobil Corporation (NYSE:XOM) 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 the Russian state company Rosneft RN-Astra and Sakhalinmorneftegas-Shelf; the Japanese corporation SODECO; and the Indian state oil company ONGC Videsh Ltd.

Since the first Sakhalin-1 well was drilled in 2003, six of the world’s 10 record-setting ERD wells have been drilled at the project. The specially designed Yastreb rig has been used throughout, setting multiple industry records for measured depth, rate of penetration and directional drilling.

The project team applied ExxonMobil proprietary technologies, including Integrated Hole Quality (IHQ) technology and the Fast Drill Process, to deliver the Z-11 well.

Released January 28, 2011

Used in conjunction with IHQ technology was an optimization process called Fast Drill, which is a unique energy-based analysis tool and work process that allows rig site and drilling engineering personnel to maximize performance in every foot of hole drilled.

The Odoptu OP-11 well reached a total measured depth of 40,502 feet (12,345 meters or 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 feet (11,475 meters or 7.13 miles). Exxon Neftegas completed the record-setting well in only 60 days using ExxonMobil’s Fast Drill Process and Integrated Hole Quality technology to maximize performance in every foot of hole drilled at OP-11.

«ExxonMobil, through Exxon Neftegas Limited, continues to successfully develop and operate the Sakhalin-1 oil and gas project to maximize economic recovery of this world-class resource,» said Neil Duffin, president, ExxonMobil Development Company. «The application of ExxonMobil technologies and processes has been instrumental in the success of this objective.»
