Snorre Field Celebrates 10th Birthday

In the shadow of more highly profiled offshore oil fields in the North Sea is Snorre - which has steadily grown during a decade of production and now holds the second-highest volume of remaining recoverable reserves in the Norwegian sector. According to the original development and production plan (PDO), the Hydro-operated Snorre field - which started producing in August 1992 and lies in the north part of the Tampen area - should be dry of oil and gas in about 18 months, says Snorre field manager Astor Tjervaag. Thanks to constant upgrading of estimated recoverable reserves - due to innovative solutions and new technology - nothing could be further from the truth.

Snorre has a complex reservoir with significant remaining resources and huge potential for the additional development of recoverable reserves, Tvervaag explains.

Only Ekofisk - which has numerous deposits scattered across the south part of the North Sea - surpasses Snorre with remaining recoverable reserves.

The Snorre field and nearby satellite operation Vigdis produce some 270,000 barrels per day. It is expected this level can be maintained until 2006. "Through hard work, active drilling and the implementation of new technology the estimates for recoverable reserves have gradually climbed. This is also true for the extension of Snorre's plateau production. A lot has happened during the past 10 years and it's satisfying to see Snorre still has about the same volume of recoverable reserves as originally estimated," Tvervaag comments.

The Snorre was originally estimated to contain, respectively, 225.3 million cubic meters (m3), or some 1.417 billion barrels oil, and 8.9 billion m3 gas, according to the Norwegian Ministry of Petroleum & Energy . To date, Snorre has produced about 100 million m3, or some 630 million barrels of oil, and 15 billion m3 gas. At the end of 2000, Snorre was estimated by the Ministry to still contain 145.3 million m3, or 914 million barrels oil, and 5.4 billion m3 gas.

On January 1, 2003, operatorship of Snorre and all other presently Hydro-operated fields in the Tampen area passes to Statoil.
