What happened in Reservoir section:
On second MDT got stuck with Saturn packer and had to release electrical cable head and fish wireline toolstring.

What Was Planned

Perform a wiper trip after second MDT run.

What Was Learned

A wiper trip to condition mud and ream ledges is neccessary before a second MDT run is performed (depending on when it happens but after several days with OH exposed without any conditioning increases risk)

What Actions Are Required

Plan for wiper trip between MDT runs when OH has been exposed for several days without any wiper trip inbetween.
