Havsule Drilling Behind Schedule

Bad weather and rough seas have delayed drilling at BPís Havsule prospect in the Norwegian sector of the North Sea by three weeks. Havsule is located on Moere Basin block 6404/11-1. The well was spudded last month by Saipamís semisubmersible, Scarabeo 5. BP said that landing of the BOP in 4900 feet of water is a very weather sensitive operation, and this took an extra three weeks compared to the original timeframe. Average wave height reached 6-8 meters, with peaks hitting 12 meters and installing the BOP requires significantly less wave height of 3-4 meters.

The BOP was successfully landed on the seabed on January 2 and by January 7 drilling had reached a depth of approximately 7,200 feet. Preparations are underway to perform a leak-off test at the 20-inch casing shoe before drilling continues to a depth of 8,037 feet.

BP is operator of block 6404/11 with a 35% interest. Partners include Petoro with 25%, Conoco with 20% and TotalFinaElf with the remaining 20%.
