17 Oct. 2001 — BP, and its co-venturers, will develop phase 1 of the Clair oil and gas field at a cost of around 650 million (pounds).

Currently the largest undeveloped resource on the UK Continental Shelf, the Clair field was discovered in 1977, some 75 kilometres to the west of the Shetland Islands, in 140 metres water depth.

Scott Urban, Group Vice President for BP's North Sea operations, said the company was delighted that the project was moving ahead.

"When Clair was discovered we knew we had a challenge on our hands to develop the field, given the technical difficulties at that time in doing so. But I'm pleased to say that technology has advanced to the point where this difficult development is now viable. As operator of the project we are delighted to see so much work over the years, finally being rewarded.

"The development of Clair represents a significant investment for all the co-venturers. It also shows that there are still opportunities to invest in the North Sea and Atlantic areas of the UKCS. I believe there will continue to be for many years to come."

Mr Urban said one of the keys to moving the Clair project forward had been the strong degree of alignment among the co-venturers on a range of issues and a shared determination to see the Clair development succeed.

The first phase of the Clair development involves recovery of oil and gas from the central area of the field. The objective of the Phase 1 development is to deliver first oil in late 2004.

It is estimated that phase 1 of the Clair development will produce recoverable reserves of 250 million barrels. If successful, future satellites could tap outlying areas and significantly boost this figure.

Plateau production from the Phase 1 development is expected to be 60 thousand barrels of oil per day and 15 million cubic feet of gas per day. The development will comprise a single steel jacket and associated topside and integrated drilling facilities.

The co-venturers in the Clair development are:

BP(operator) 28.6%
Conoco 24.0%
Chevron UK 19.4%
Enterprise Oil 18.7%
Amerada Hess 9.3%
During the Front End Engineering Design(FEED) process, carried out earlier this year, the project co-venturers sought new approaches to project delivery that have not been considered by previous UKCS developments. This has included incorporation of best practice globally in terms of project execution including input from the Gulf of Mexico. This effort resulted in Clair becoming competitive in the co-venturers' worldwide portfolios.

The Clair co-venturers believe that by taking these and other 'best in class' practices and combining them with the best from the UK, it will result in a facility that is not only cost competitive, but also a leader in health, safety, environment and reliability measures.

Notes to Editors

The Clair field is located approximately 75kms west of The Shetland Isles in about 140 metres of water. It covers an area of 220 square kilometres.

The Clair field was discovered in 1977. Between then and 1990, 10 appraisal wells were drilled, followed by a further 5 appraisal wells between 1990 and 1995. A 3D seismic survey was also carried out during this period. A further 2 appraisal wells were drilled in 1997 and an extended well test conducted.

Clair Phase 1 Development will focus on the Core, Graben and Horst reservoir areas which have estimated oil in place of approximately 1.75 billion barrels, of which, 250 million barrels can be recovered.

The platform jacket for Clair will be located over an existing well. The jacket is a four legged single steel structure. Its height is approximately 165 metres. Both jacket and topsides are designed for fabrication, transportation and installation as single fully integrated lifts that require access to the heaviest lift capability vessels on the installation market.

It is planned to drill 15 producing wells, 8 water injectors and one drill cuttings reinjection well.

Produced gas from the Clair project will not be routinely flared but either exported to the Magnus Enhanced Oil Recovery western gas pipeline or reinjected into the reservoir through a well.

Produced water and drill cuttings resulting from the development, will be reinjected.

The Clair field covers five licence blocks - 206/7a; 206/12; 206/8; 206/13a; and 206/9.
