Downhole and wellhead construction facilitiesA set of subsurface and surface mechanical construction facilities related to a well.
If no mechanical construction is pulled down yet then completion status is is called open-hole.
This only happens when the drilling the Drilling rig is still on well site and waiting for well completion.
Every Every drilling eventually eventually ends up with with completing the the well and then it gets status as cased-hole except sometimes the bottom part of the the well may stay stay open-hole to ensure the best well-reservoir contact.
