comments: Continued investigation of the incident. Simulated incident. Found HTS rollers got stop signal but had too long slowing down period. Investigated for hydraulic or electrical error. On 2nd simulation attempt the system worked normal, rollers stopped as they should. Unable define the error.

comments: Held tool box talk and leak tested Cement line to rig floor 200 bars/5mins. Attempted to pressure test the 2nd cement plug. Pressure up against shear ram 50 bars and increased pressure in 20 bars increments. At 110 bars pressure drop rapid to 70 bars. 0.95 m³ pumped 0.6 m³ return. Trip tank steady.

comments: Continued washing down from 2401m to 2587m w/ 2500 lpm, SPP 167-175bars. Tight/overpull at 2587mt. Started rotation at 20rpm. Continued to wash/ream down from 2587m to 2629, Torq 5-10 kNm. Occasionally WOB at 5 mt for a few seconds, otherwise no WOB.
Took weight at 2629m 10 MT. Washed through. Reamed to 2631 m. Stopped rotation and set down 10 MT with 2500 lpm, firm cement at 2631m (TD).
50/50 cement/formation over the shakers. No gain/losses during clean out.

comments: Circulated hole with 2500 lpm 80 rpm and reciprocated the string. Size of the cutting in return: Cement Ø1" and formation chips 2" x ½" x 1/8". Circulated 3 bottoms up. After 2nd bottoms up 90 % formations cuttings back. No gain/losses during clean out. Decided to pump out to 9 5/8" casing shoe.
