Yesterday, temperature and CBL loggings were carried out between 13 and 19:30 pm. The results indicate that TOC was at c. 100 m depth and that the anchor casing is well bound in general. An exception is an interval between 1415 and 1500 m depth, where CBL show little signs of cement bounding. At 23:30 pm the cementing of the anchor casing was finished. The uppermost part of the annulus was filled with cement, using 5.6 cubic meters of cement slurry. A CBL logging is planned in the afternoon.

Yesterday attempts to loosen the string went on by using different approaches. Pumping rate through string or kill-line was varied, tork added occasionally and jarred upwards or downwards but without progress. A temperature log was run in the well down to 1977 m depth from 20:37-00:08 last night (see below and fig. 1, 2 and 3). Because of positive results of the temperature log, it was decided to continue with high pumping rate through motor, downwards jarring and adding many high viscosity pills. At 06:20 the string finally got loose. Now we are pulling out of hole with slow rotation of string and pumping ~20 L/s through the string.

Attempts to loosen the string are still ongoing. Yesterday, at noon, the string had moved some 12 m upwards. At 14:00 hours down-jarring was started with 50-60 L/s flow on kill-line and pull up to 200 tonnes. Soda was added to the fluid in order to dissolve the cement particles within the fill enveloping the BHA components. Tactic was changed in the evening, pumping 60-70 L/s through string, pulling up to 260 tonnes and adding torque to 2400 daNm together with down-jarring but without any progress. During the night, the tactic has been to pump 65 L/s through string, adding torque to 2150 daNm and jarring. This morning pump through motor is 65 L/s in attempt to shake the fill loose. Loss of circulation is total.

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.

Yesterday morning, side-track sliding continued, with WOB varying from 2-8 tonne. Before noon ROP was kept between 0.5 – 7 m/h. Around 15:00 drilling with rotation started. Pumping was increased to 60 L/s, raising the stand-pipe pressure to ~ 170 bar. WOB was kept between 6-11 tonne with increased but more variable ROP’s due to higher WOB. Unfortunately the data system broke down at midnight so no data were recorded during last night. TD was reached 05:00 this morning at 2005 m depth. At 05:30 the drill string got stuck with bit 8 m above bottom of well. Now the flow through motor is varying from 20 – 60 L/s in attempt to shake the string loose.

Side-tracking is continuing and cutting samples look promising. The last few samples contain ~ 70-80% rock cuttings of fine-medium grained basalt. Most of them seem to be freshly cut, while a few somewhat rounded grains and some crushed grains are probably remnants from the initial drilling in this depth range.

Yesterday, just before noon and after drilling through a soft cement plug, a solid one was reached at 1910 m depth. While drilling through the soft plug, a few pills were pumped down with the circulation fluid to clean the well. From noon yesterday the ROP has been kept around 0.5 m/h and the WOB has gone up to 5 tonnes. Side-track drilling commenced yesterday at 13:00 hours, first by attempting to form a ledge at 1911 m depth by sliding repeatedly over the same interval. At 16:25 pm the actual side-track drilling started and is still continuing today. Circulation losses are around 5.5 L/s this morning.

After the gyro-run yesterday morning drilling the cement (sliding) in an attempt to side-track commenced 06:15 at 1835 m depth. WOB was kept low, around 1 tonne, and ROP’s were kept at 0.5 m/hr to try to ensure a successful side-track. Circulation losses were variable but generally around 10 l/s when measured on the pumps. Last night ROP’s increased markedly although WOB was kept low. This occurred at ~1846 m depth, shortly after midnight. After reaching ~1849 m depth there appeared to be little or no resistance left in the cement plug and we were clearly “back” in the hole again.

BHA was run into the hole until the TOC was reached at 22:50 pm at approximately 1819 m depth. There the ROP decreased considerably, i.e. from c. 40 m/h to c. 10 m/h. Some minor obstacles were entered at 1210-1215 m, 1740-1742 m and 1749-1752 m depth. Below 1777 m the ROP started to decrease. The plug was then drilled further to 1835 m depth. At 06:15 am this morning directional drilling of the sidetrack started. The ROP is kept close to 0.5 m/h with a minor WOB. Loss of circulation has been around 10 L/s. The plan is to drill carefully with ROP at 0.5 m/h during the day and clean the hole regularly with high viscosity pills.
