What happened in Reservoir section:
…., F/C at shoe, 400 liter gain in trip tank. Closed in well, checked for PBU (none), RIH to TD, circ. BU, last 25% volume TD to mudline over chokes. No appreciable gas.

What Was Planned

POOH core #2 according to good practice: F/C on bottom (static), pump out to shoe, F/C…

What Was Learned

Possibly caused by high levels of rig heave causing string to be “sucked” through float, causing apparent gain in trip tank.

What Actions Are Required

After pumping back again to shoe, F/C performed with IBOP closed to minimize sucking effect. Well was static.
