comments: Changed primary seal in diverter overshot. Meanwhile performed test against cement plug : Closed shear ram. Topped up well with mud by circulating accross choke and kill lines. Perfomed line test against kill valve on BOP - 200 bar / 5 min - ok. Opened kill valve. Pressured up on well against cement plug to 50 bar and observed steady test. Continued pressuring up in 20 bar increments, observed steady test on each level. Tested cement plug #2 to 162 bar / 10 min (0,74 % drop). Pumped and bled back 1022 litres. Meanwhile changed primary seal in diverter overshot.
