comments: Broke circulation at 9 5/8" shoe and stepped up rate to 700 lpm as limited by erosion figures for side entry sub. Circulated bottoms up. Standpipe pressure rose from 10 bar to 30 bar throughout circulation. Mud weight out 1,39 sg rising to 1,43 sg towards the end. Mud weight in 1,45 sg. Gas peaked at 7% and levelled out on 0,3% towards end of circulation.

comments: RIH with 5" DP from 2750 m to 2996 m MD, held wireline tension contant at ~7000 lbs. Made up TDS to each stand to limit backflow. At 2835 m MD, got indications on downhole tension that WL and fish were free, attempted to pull fish free with 12000 lbs WL tension - negative - WL still stuck.
