comments: Lined up to test MS-seal from above. Pressurized to 35 bar, dropped 0,6 bar 5 min - ok. Pressurized to 345 bar. Pressure dropped 0,7 bar / 5 min in the start but with gradually increasing fall off trend. Dropped 1,8 bar / 5 min towards the end of the test.  Pumped and bled back 373 liter. Bled off pressure and discussed situation. Decided to re-attempt pressurizing MS seal with PADPRT tool.

comments: Attempted to replicate test on MS seal testing against WBRRT. Conducted low pressure test to 35 bar / 5 min - ok. Pressured up to 345 bar, not able to obtain good test, pressure leaked off at approx 3,5 bar / 10 min (~1%) and did not stabilize. Topped up drillpipe and observed for flow up drillpipe. Observed flow from drillpipe. Discussed situation. Decided to pull WBRRT and install test plug for test of MS-seal and BOP.
