The mast of drill rig T?r in sunny weather today.

TD was reached 05:00 yesterday morning at 2005 m depth. The string got stuck at 05:25 while cleaning the well, with the bit 8 m above bottom of well. Pumping through motor was switched between 20-66 L/s in attempt to shake the string loose. At 14:00 hours, the tactic was changed, pumping was varied between 5 and 70 L/s, while pulling occasionally on the string and torque added as well. From 16:45 hours the jar was hammered downwards regularly without progress. A temperature log was run in the well between 00:27-01:37 last night. At 03:00 jarring upwards and pulling with up to 200 tonnes was started. This resulted in the string moving 2-5 cm up with each release of the jar. At 08:00 this morning the string had moved 6.3 m in total. Circulation loss at 07:00 is 40 L/s.
