No significant problem was encountered in the drilling phase. Due to\r\nfish in the hole logs were not run below 2563 m.

A\r\ntrue gas-water contact was found at 4163 m at the base of the Ness Formation. Both\r\nthe Cook and the Statfjord Formations were water bearing. First trace of\r\nfluorescence in the well was reported in minor sandstones in the Lista\r\nFormation at 2115 m. Traces of light coloured fluorescence was observed\r\nsporadically on limestone down to top Brent Group, generally associated with\r\nelevated drill gas readings.
