comments: Filled drillstring. Stepped rate up to 2500 lpm. Tested MWD. Adjusted ECD values - ok. 

Meanwhile tested 3" chiksan line to F-5 - observed minor leaks/drips from line. Hammered up connections in question. No leaks on valve assembly.

comments: Prepared for doing slip and cut. Rigged up swadge on drillstring to maintain circulation in well. Stepped up pumps to 2500 lpm as dictated MWD. 

Meanwhile tested 3" chicksan line to F-5 against closed lo-torque - 2,5 bar / 10 min (0,65%) - ok.

comments: Established parameters for washing down / cleaning rathole : Flow  3000 lpm / SPP 128 bar / Rotation 60 rpm / torque 6 kNm. Washed down from 1368 m to 1374 m MD. Observed sudden torque build up followed by pack off - pump pressure peaked at 180 bar. String free to move down. Regained circulation at 3000 lpm / 128 bar SPP. Worked string upwards and pulled into casing shoe at 1368 m MD while circulating at 3000 lpm.
