comments: Ran 10 3/4" Itco spear 3 m into 10 3/4" tie-back casing and latched same. Took up/down weight 82/79 MT.  RIH with tie-back casing on 5 1/2" HWDP (LS-1). Put meter marks from casing hanger landing shoulder. Tagged with 4 MT at ~139,4 m, i.e. 30-40 cm shallow - no colour marks observed in WH B-annulus outlet. Re-attempted tag - same depth.

comments: Decided to attempt to screw in 1-2 turn in order to verify tie-back adapter depth. RIH and tagged approx 10 cm deeper than earlier. Observed lower orange and white band in B-annulus outlet. Measured required distance for adjustment sub travel (15") and decieded to continue according to plan.

comments: Set torqe limit to 2700 Nm. Made 3 attempts to enter tie-back adapter. Entered tie-back adapter on 4th attempt and observed weight increasing about 3-4 MT for each turn. Slacked off to neutral (80 MT) for each turn achieved. String stalled out at 2700 Nm after 5+ turns achieved. Took 10 MT overpull. Rotated at 1 rpm. Attempted make up to 10 000 Nm (optimum torque) - spear started to slip at 5500 Nm. Re-engaged spear. Adjusted torque setting to minimum torque 6600 Nm -spear started to slip at 5500 Nm. Re-enaged spear. Set torque limit to 10 000 Nm,  increased rotation to 3 RPM. String stalled out on 10 000 NM (optimum torque) - ok.

comments: Pressured up on drillpipe to 140 bar to activate horizontal dogs. Pulled back 0,4 m and confirmed engaged in vertical dog profile by 9 MT overpull. Rotated string with 22 righthand turns. Observed colored band through B-annulus outlet to confirm adjustment sub collapsing. Increased overpull to 30 MT and continued rotating until TDS stalled out on 9 kNm and overpull reduced. Slacked off string to 28,4 m MD mark and waited for 2 min. Bleed off pressure on DP. Obtained a total of 17" travel on adjustment sub.
