The well will be plugged due to the fact that that well 6406/2-2 was temporarily abandoned by Saga in 1996, and a decision has been made to permanently plug the well according to the requirements set down in NORSOK Standard D-010.
The plugging is scheduled to start after West Alpha completes drilling for Statoil on the Kristin field, stipulated to February 2006, before the start-up of well 6506/11-8.
Well 6406/2-2 was drilled on the B structure (Lavrans discovery) in the eastern part of the block, south of an east-west trending cross fault. The discovery well 6406/2-1 had previously been drilled on the northern segment of the B structure. The cross fault was suspected to act as a pressure barrier between the two segments, causing variation in fluid types. The main objective of well 6406/2-2 was to prove hydrocarbons and verify fluid contacts in the southern segment, which seemed to differ from the northern segment in both the nature and intensity of the seismic amplitudes. An additional objective was to investigate any differences in reservoir development between the two segments.
