RE:Typical demob procedureBackloading of sack room, bulk mud and cement products etc. But first P&A the well. They usually skid rig after installing a tree in the well head before pulling riser and BOP. If you see a rig skid with lots of supply boat activity then it may signal a demob.
But it could also signal a rip current which happened to us on a Statoil well offshore Venezuela in 2006 on the Sovereign Explorer. Anyway wait for NR or get confirmation from lj who knows everything.
