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.
