sum24Hr: Ran in hole with 12-1/4" TrackMaster milling assembly and milled window from 424,3 m to 428,2 m. Continued to drill formation and mill window with string mills to 436, 5 m. Water melon mill 2 m out of window. Reamed and dressed the window from 421,5 m (top) to 428,2 m (bottom). Slided through window with milling assembly. Picking up a few tons of weight at 421 m and 425m.
Displaced the well to 1,20 sg KCl/polymer mud and flow checked. Pulled out of the hole from 436,5 m to 200 m
Experienced a dropped object on the rig floor. A 0,17 kg bolt came loose on the TDS and dropped 30 m to rig floor (50 Joule). The incident was investigated. The bolt was re-installed and the TDS was further checked for loose items.

comments: Racked back stand - depth 416 m and investigated dropped object. Meanwhile monitored well on trip tank. A 0,17 kg bolt had loosened and unscrewed from the TDS and dropped 30 m to rig floor (50 Joule). Re-installed bolt and lock wire. Changed out other damaged lock wires. Further investigated for loose items and potential dropped objects.
