comments: Ran 13 3/8¿ P110 72# casing from 1476 m to 1500 m MD. Encountered tight spot at 1481 m MD. Stepped up pumps to 900 lpm. Appled 3 rpm within 15 kNm limit. Worked restriction every 12 m indicating centralizers hanging up in shoe or kick off area. Max set down weight 25 MT. Set casing joint in foxhole prior to making 2nd grip with PRS pick up tool - this method seemed to make the stabbing more accurate.
