Conoco has encountered hydro carbons in a high temp erature/high pressure well in the Norwegian sector of the North Sea. Well 1/5-3SX was plugged and abandoned when high well pressures were encountered after drilling to a depth of 5,056 ft using the Byford Dolphin semi. Conoco has not released plans as to whether further drilling will be continued on the block.

A steel processing platform has been proposed for the optimal development of the Kvitebjorn Field in the Norwegian sector of the North Sea. Statoil and partners Elf Exploration and Norsk Hydro feel that this solution provides the best economics, offers the ability to drill without the need of a separate rig, and provides flexibility to produce smaller fields in the area. Kvitejborn is a gas and condensate field with reserves estimated at over 50 bcf of gas. The gas from the field will be transported via pipeline to the Troll gas facility or via the Oseberg or Heimdal fields.

The first Statoil cargo of 600,000 bbl of oil from the Schiehallion Field, West of Shetland, has been sold. The first cargo is on its way by shuttle tanker to the Sullom Voe terminal in Shetland for storage and transshipment. Peak production from the field is expected to be close to 140,000 b/d. Statoil holds 6% interest in the field and is entitled to about 9,000 bbl.

Further gas reserves have been confirmed by BP Norge's exploration well 6305/7-1 into the southerly part of the Ormen Lange dome off mid-Norway. According to the NPD, provisional estimates suggest reserves in the order of 200-400 Bcm. Gas was found at a depth of 2,900 meters in Early Tertiary sandstone. The well, which was drilled by the Ocean Alliance semisubmersible in 857 meters of water. This marks the first deepwater well in Norway to be tested, following the development of special equipment.

Middle East

Samedan Mediterranean Sea has entered into an exploration participation agreement for nine licenses offshore Israel. The agreement encompasses about 890,000 acres in water depths ranging from 2,500 ft to 5,000 ft. The first well is planned for early spring 1999 and will be drilled to approximately 7,250 ft to test a prospect that has been delineated by recent seismic. Samedan will pay 53.3% of the well cost to earn a 40% working interest in the licenses.
