7 Mud report 2 /4" hole 3 m m: 3 m drilled, /" casing A cement plug was set and drilled down to 66 m before a window was cut through the casing from 3 m to 62 m. The hole was then cemented up to m. This plug was dressed off down to 3 m before a "navy drill" was run in hole. At 2 m a formation integrity test was performed to.6 rd equivalent mud weight. The 2 /4" hole was drilled down to m with a navy drill and bent sub. At this depth a core was taken down to 4. m. New hole was then drilled down to 23 m. Seven cores were taken down to 2 m before intermediate logs were run. At 6 m core no. 3 was pulled and a rockbit run in hole. 2 /4" hole was then drilled down to 34 m before the core barrel was run in hole. Core no. 4 was taken from 34 m to 32 m. When running back in hole, tight spots were seen from 3 m to 32 m. During drilling down to 32 m the bit stalled out several times. 44 kn overpull was seen when pulling out the first stands. When running back in hole, no problems were seen. 2 /4" hole was then drilled to 326 m before the hole was logged.

A formation integrity test was performed to. rd equivalent mud weight. New hole was then drilled from 32 m to 32 m before the turbine and stratapax bit was pulled. A rock bit was run in hole and new hole drilled to 3 m. The bit was pulled. Tight hole was seen back to m. When running back in hole 2 m fill was found. Drilling continued to 44 m. The next bit was drilled to 4 m before it got stuck. After reducing the mudweight from.3 rd to. rd the string was jared loose. The bit was pulled. When running back in hole to 444 m tight hole was seen. After reaming from 444 m to 4 m new hole was drilled to 43 m before a wipertrip prior to logging was made.
