Downhole and wellhead construction facilities

If no mechanical construction is pulled down yet then completion status is open-hole.

This only happens when the drilling rig is still on well site.

Every drilling eventually ends up with completing the well and then it gets status as cased-hole except sometimes the bottom part of the well may stay open-hole to ensure best well-reservoir contact.
