10:15 - 10:45: P/u left hand tie-back adapter torque tool and m/u to x/o
10:45 - 12:00: RIH torque tool on 5,5in left hand DP. From surface to 140. P/u singles from cantilever
12:00 - 12:45: Left hand x-over arrived on the rig. Inspected and discovered it was right hand x-over. Evaluated situation. Meanwhile performed hydraulic test on bx4.
12:45 - 14:00: P/u 1x more joint of DP and m/u to string. Attempted to break off tie-back adapter using rig tongs on DP. Pulled 28knm. Cathead fully stroked out. No success
14:00 - 14:30: Evaluated situation. Meanwhile performed tests on aft iron roughneck
14:30 - 15:15: POOH from 140m to surface. L/d torque tool. Clean and clear rig floor
15:15 - 15:30: Performed pre-job meeting to p/u drill collars from deck
15:30 - 17:45: P/u and RIH 8,25 DC from surface to 90m joints). R/b same in derrick
17:45 - 18:00: Performed pre-job meeting to p/u guns
18:00 - 18:15: R/u to run guns
18:15 - 19:00: P/u and m/u TCP gun BHA from surface to 17m
19:00 - 19:15: Performed pre-job meeting to handle guns w/ new crew
19:15 - 19:30: Continued to m/u guns BHA to 18m
19:30 - 20:30: RIH w/ guns on 5,5in DP to 138m
20:30 - 21:00: M/u TDS and positioned guns at 151. 7m, closed uprs and applied 20 bar to IBOP, opened to confirm line up. Up/down weights 72t/68t, flushed ball seat with 222 l/min. Opened uprs, broke out connection and dropped 1 3/8in ball. M/u connection and positioned guns at firing depth 144,5-147,5m shot), closed uprs and lined up through fully open choke
21:00 - 21:30: Pumped down ball with 160 l/min, sheared ball seat at 150 bar. Indication of guns firing vibration on surface). Top shot at 144,5m, bottom shot at 147,5m. Continued pumping with 150 l/min until returns, increased to 770 l/min, observed slight gain of 500ltr and then losses of 60m3/hr. Pumped 1,5 times btms up, gas observed and still on losses
21:30 - 22:15: Stopped pumping, left choke open and opened uprs, observed increase in flow. Close uprs and closed choke, monitored for pressure on chole. Initially 1 bar, slowly increased to 2. 9 bar then leveled out. Opened choke and slowly bled off pressure to 1 bar, closed choke and monitored for pressure build up, OK, no build up observed
22:15 - 23:30: Opened choke and circulateed with uprs closed with 760 l/min, initially observed 60m3/hr losses. After confirmed returns increased flow rate to 890 l/min 2,5 bar, MAX gas of 4. 3 Continued circulating until gas content curve showed downward trend. Total losses since punch 21m3
23:30 - 23:45: Stopped pumping and flowchecked through fully open choke, static. Opened uprs and flowchecked on trip tanks, static
23:45 - 00:00: Started POOH from 147m

24-hour summary: attempted to release tieback adapter several times w/ no success perforated below 10 3/4in subsea CSG hanger circulated gas out
