Project Description
Located off the Irish coast in relatively deepwater, Corrib is the first commercial gas discovery in the Irish Isles Atlantic margin. Consisting of a reservoir 9,843 feet (3,000 meters) below the seabed, Corrib is a dry gas field with the reservoir located in Triassic Sandstones in the Atlantic Ocean. It is approximately 50 miles (80 kilometers) from County Mayo and lies in Blocks 18/20 and 18/25.

In 1996, the Corrib Field was discovered by Enterprise Oil, which was acquired by Shell in 2002. Shell, now the operator, owns 45% interest; Statoil owns 36.5%; and Vermillion Energy Trust owns 18.5%.

Shell announced the suspension of the project to facilitate further discussions with opposing parties. For a year, independent safety reviews were conducted to address various safety concerns in relation to the project.

Field Development

The Corrib field was developed as a subsea production facility with onshore processing, utilizing some of the most advanced technology available in the oil and gas industry.

Field development links current appraisal wells to a subsea manifold, and the wells are tied-back to shore by a pipeline. Engineers decided a platform wasn’t necessary, since the wells are controlled from land. Gas is then processed at an onshore terminal with the capability of processing up to 10 MMcf/d (.3 MMcm/d).

Corrib has an estimated field life of about 15 to 20 years and at its peak will supply up to 60% of the natural gas needed in Ireland.

The field is slated to commence production in 2014.

Irish Planners Ask Shell to Rethink Gas Pipe Route
Type: Status Update

Nov. 2009 - Ireland's planning board, An Bord Pleanala, has asked Shell to consider an alternative route for a six-mile (nine-kilometer) onshore pipeline that will deliver gas from Corrib, a dry gas field located off the Irish coast in relatively deepwater in the Atlantic Ocean. A deadline of February 5, 2010 has been set for Shell to complete an environmental impact study for the route through a bay further away from the town of Rossport. The original route has been the subject of some controversy over the last several years, primarily due to safety concerns and lack of local involvement in the decision making process. With all Corrib wells already drilled and first gas planned for 2010 or 2011, the onshore gas processing terminal is 80% complete.

Irish Minister Marks Vermilion's Entry into Corrib Gas Devt
Type: Operator Update

Aug. 2009 - Mr. Conor Lenihan, Minister of State for Natural Resources and Knowledge Society, welcomed the entry of a new company into the Irish petroleum market following the sale of Marathon Petroleum Hibernia Limited's 18.5% interest in the Corrib gas field to Vermilion Energy Trust. The final sale proceeds will range between $235 million and $400 million, subject to the timing of first commercial gas from the Corrib gas field. The Operator, Shell E&P Ireland Ltd. expects first gas to occur during the period between late 2010 and early 2011.

Vermilion Snaps Up Marathon's Stake in Corrib Development Off Ireland
Type: Operator Update

Jun. 2009 - Marathon entered into a definitive agreement with Vermilion Energy Trust, under which Vermilion will purchase Marathon's wholly owned subsidiary, Marathon International Petroleum Hibernia Limited, which holds Marathon's 18.5% interest in the Corrib natural gas development offshore Ireland. The companies expect to close the transaction, subject to Government and regulatory approvals, during the second half of 2009. The final sale proceeds will range between $235 million and $400 million, subject to the timing of first commercial gas at the Corrib field.
