comments: Trapped 20 kNm in with shaft and applied TDS break. Put tong on and pulled 20 kNm, released brake and pulled with tong to 25k n/m. Applied TDS brake. Pulled up to max 30kNm with Rig tong, observed torq reduced on TDS Shaft. Took off Rig tong, rotated TDS counter clockwise to make sure free. Made string back up to 2kNm. POOH, visually checked all connections. No connections have been observed backed out

comments: 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 (top-bottom shot), closed UPRs and lined up through fully open Choke

comments: Pumped down ball with 160 l/min, sheared ball seat at 150 bar. Indication of guns firing (sound, 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

comments: 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
