What happened in Top hole:
Took onboard 90 m3 ready mixed kill mud in Stolsfjorden

What Was Planned

Taking onboard 90 m3 1,5 sg kill mud in Stolsfjorden

What Was Learned

Made the rig being ready to spud as soon as cross tension was completed.
Takes all the stress out of having to mix mud while anchor handling and whether to be on operational draft or not when getting allowed.
And for this well it saved a lot of time as we had not managed to bring onboard barite and was not able to get bentonite out of the silo 🙁

What Actions Are Required

Plan for mixing initial agreed volume of kill mud onshore and ideally get it onboard while rig along side at Green Yard to avoid bulk handling in the fjord.
