LONDON, Apr. 24 -- Dana Petroleum PLC will sidetrack well 210/24a-11 into the neighboring East Rinnes structure on Block 210/24a in the northern UK North Sea after discovering oil on the West Rinnes structure, also on Block 210/24a.

The well produced up to 7,800 b/d of 32º oil during a drill stem test from the Brent reservoir on the West Rinnes structure. Dana said it is confident the size of the East Rinnes structure is similar.

The well reached a total measured depth of 6,470 ft and the flow rate was limited by test equipment on the drilling rig, the company said. Dana is encouraged by initial tests that the well's oil quality is similar to that being produced at Hudson oil field 5 km away. The well found excellent quality sands throughout the Brent sequence, Dana reported.

"A comprehensive set of wireline log data has been acquired, including pressure data and oil samples," Dana said.

Tom Cross, Dana's chief executive, said the results "exceeded our predrill expectations. The discovery of good quality oil at West Rinnes gives strong encouragement for a number of other prospects in this immediate area, including East Rinnes, which will be drilled imminently, and also West Hudson, North Melville, and southwest Rinnes, which have yet to be drilled."
