comments: Made up TDS. Took up/down weights 253/199 MT. Pumped at 450 lpm while running in slowly with landing string. Observed pressure bulid up and lost returns at 2406,4 m MD indicating seals engaging 9 5/8" liner sealbore. Stopped pumps. Observed stinger shroud shearing some 1,20 m further in and got hanger landing depth 0,8 m (total of 1.2+0.8=2m) further in at 2408,4 m MD.
