comments: Reduced pump rate to 200 lpm / 8 bar, dropped setting ball and pumped same down pipe until landed out in ball seat. Set 9 3/8" liner hanger; pressured up to 165 bars for 2 min, than reduced pressure to 70 bars. Set down 25 tons and bled off pressure. Released liner hanger R/T according to Weatherford representative instructions; Pressured up on landing string to 240 bars, held pressure for 2 minutes and then bled off pressure. Pulled to up weight (97 tons) + 1 m to activate the MX ball seat. Set down 20 ton and sheared out ball seat.

comments: Circulated and conditioned mud prior to liner cementing job; broke circulation and gradually increased pump rate to 2000 lpm / 44 bar, circulated one open hole BU volume. Mud weights in/out = 1.20 sg, no losses seen. Meanwhile held pre-job cement meeting with involved personnel prior to liner cementing operations; reviewed check lists and relevant safety / operational issues. Leak tested surface cementing line to 300 bars for 10 min - OK.

comments: Displaced cement slurry in place with rig pumps: Started to pump at 800 lpm / 4 bars, observed bottom wiper plug shear. Increased pump rate to 2100 lpm / 21 - 80 bar, reduced to 600 lpm / 39 bar prior to bumping top plug. Bumped top wiper plug at 1074 strokes, corresponding to 97 % pump efficiency. No losses seen during the entire cementing and displacement operations.
