The objective was to test the hydrocarbon potential in the Paleocene on\r\nthe west flank of the Cod structure, and to confirm the gas and condensate\r\ndiscovery made by the 7/11-1 well.

Tight hole was\r\nexperienced when pulling out of the 17 12" hole. The hole was washed back\r\nto TD and mud weight increased to 14 ppg. Logging and casing operations could\r\nthen be successfully carried out.
