Cementing of the plug finished at 16:00 yesterday. Logging of the well with a weight indicate a TOC at 1903 m. This morning, when the drill string was lowered down to the top of the plug, it appeared that it was not hardened enough. Some more time is needed for hardening of the cement.

Yesterday attempts to catch the fish were not successful. Last night the string was pulled out of the hole. Preparations for cementing a ca. 100 m thick plug above the fish are ongoing.

Repairs to the pipe handling system and the wires were completed by 10:15 pm last night. While the baskets were raised again, was the hole temperature logged. RIH to attempt to retrieve the remainder of the fish commenced at 3:00 am and at 7:45 am is string at 800 m depth.

Repairs to the pipe handling system were delayed yesterday because of breakdown of the mobile crane that had to be used to lower the baskets. Repairs to the drill pipe feeder are still in progress and a preliminary estimate is that repairs may be completed after lunch.

Attempts to retrieve the fish were stopped at noon yesterday. The fishing tool could not be released from the fish again and so explosives were placed at 2056 m depth last night. The fish was successfully blasted at 00:45 am. Part of the fish, which extends down to 2055 m depth was successfully retrieved this morning (6 collars). The detonation had ripped up the collar 2 m above the connection to the cross-over sub, but the connection between sub and collar had been unscrewed by the detonation as calculated.

Yesterday afternoon was pulled in fish after 25 hours of heating. First was pumped 40 L/s through string for 10 minutes to cool the string and after that was pulled in string and it moved a bit more than 1 m upwards. During the afternoon was continued to pull in the fish with up to 250 tonne or to pound with the jar, but the fish did not move any further. At 7 pm was loosing attempts stopped and the hole was left to heat until 7:30 am this morning. The attempts to release the fish this morning were to no avail and at noon were further attempts to release the fish stopped.

The hole has been left to heat up from 12:30 pm yesterday. Temperature log run was carried out yesterday and this morning preparations are underway to log the temperature in the hole again.

Attempts to get the fish loose are continuing with little progress. During the night up to 98 L/s has been pumped down hole along with polymer pills, there has been pulled in the fish with some 250-260 tonne and in between has the jar been activated without much progress.

Sleeves in the pumps were changed last night to 6” and after that up to 65 L/s have been pumped through the string at 225 bar pressure, while pulling with up to 250 tonne for 5 minutes and activating the jar in between. There have been small signs of progress with drops in the standpipe pressure at constant flow rate and the fish appears to have moved upwards slightly.

The fishing tool was over the fish at 10:00 o'clock yesterday morning. The tool engaged the fish readily but attempts to loosen the BHA have been going on since 10:30 yesterday morning with no progress. A temperature log was run last night, showing clearly that the cooling fluid flows past the 2060 m depth point where the log ended. This means that the pipe is stuck somewhere between 2060 and 2086 m,possibly between the two

Pulling out of hole continued yesterday after BHA twist-off and was finished at 18:15. Running in with fishing tools commenced late last night and the tools were over fish just after 10:00 o'clock this morning.

Drilling commenced last night. ROP's were moderate to good. Since 06:00 there have been problems with pipe getting stuck. Torque spikes, BHA probably broken, POOH (10:30).

The fish was at surface late yesterday. The carbite inserts on the bit were in remarkably good condition. The bit had however overheated and was leaking some oil. Breaking out the fish took some doing and T and P logging did not start until 20:00 last night.Preparations are now being made for running in with a bit for continued drilling.

POOH was completed at 12:30 yesterday. A temperature log was run down to 2040 m depth (TD = 2074; Fish ~32 m). The well is readily cooling down to at least 2040 m. After logging, fishing BHA was run in hole. Fish was on and loose at 04:11 this morning, after pulling with 190 tonnes. At 9:00 fish is at roughly 900 m depth.

Drilling at good ROP's yesterday. A small loss of circulation at 2038 m which was sealed with mica and nut-shells. In the late afternoon additional fractures were intersected with increased losses of drilling fluid. At this time the fluid was changed from mud to water. We re now pulling out of hole (POOH). The BHA has been severed, this occured at 00:50 this morning. TD is 2074 m.

Less progress was in drilling yesterday due to hard formation and this morning at 7:45 am is depth 2029 m. There is no loss of circulation. Inclination is 1°.

Good progress is in drilling and depth is 1996 m at 7:30 am. WOB was increased to ~18 tonne yesterday evening and during the night ROP has been 3-4 m/h. There is no loss of circulation and the inclination has been decreasing and was 1° at 1986 m depth.

Drilling resumed at 4:30 am. Currently drilling is going on with 15 tonne WOB and ~60 RPM, while standpipe pressure is 149 bar at a pump rate of 60 L/s. ROP is 2-2.5 m/hr and depth at 7:40 this morning is 1915 m.

Pulling out of hole was completed after 3 am this morning. The outmost row of teeth appeared to be worn down, but otherwise was the drill bit in a fair condition. Substantial wear were on both stabilizers. All hard facing is worn off as well as several cm of the blades of particularly the string stabilizer. Temperature log was completed by 7 am this morning and now preparations are underway to assemble BHA and RIH.

Drilling is progressing at a steady rate and depth this morning at 7:45 is 1902 m. 109 m have been drilled for the past 24 hours at an average ROP of 5.2 m/hr. The inclination has increased slightly and measured 3° this morning. There is no loss of circulation. At 09:05 am it was decided to pull out of hole in the purpose to replace the bit. Estimated time is 12 hours followed by temperature log (2-3 h) then RIH and continue drilling.

Good progress is in drilling and depth at 8:00 am is 1807 m. For the past 24 hours has been drilled 126 m with an average ROP of 7.2 m/h. There is no loss of circulation and inclination has been within 1°-2°.

Drillng is progressing at a steady but modest pace. The tool pusher is putting about 13 til 15 tonnes on the bit (WOB). ROP picked up during the night for a few hours with top speed up to 10 m/hr and average 5 to 6 m/hr. Depth at 8:00 o'clock this morning was 1584 m. During the last 24 hours (April 9th) hole made was 74 m.

The drill string with a junk-basket was at the bottom of the well by noon yesterday. Pulling out of the hole commenced around 16:00 and by 23:00 last night the junk-basket surfaced. It contained mostly angular chips derived from relatively fresh basaltic intrusions, and some of them were surprisingly large. The decision was made to maintain mud as circulation fluid instead of changing it to water in an attempt to locate leaks in the well. Afther the bit and the junk-basket were out of the hole, preparations for running in a new BHA commenced and drilling may start again around noon today.
A junkbasket, for fishing carbite pieces from the bit off the bottom, arrived by 01:30 this morning. Subsequently, running down the basket commenced and by 8 o'clock this morning it was at 800 m depth.
Circulation losses occurred yesterday morning, during the run in with BHA. Mica and nutmeg was pumped down in an attempt to decrease the losses, resulting in improving situation as the depth approached 1360 m depth. Drilling resumed at 14:30 and circulation losses continued after a while and increased late last night. At 02:15 this morning it was decided to pull out of the hole and just after 13:00 o'clock today the bit was on the surface. A temperature log was made this afternoon, in an attempt to locate the aquifer.
