Fitting your questions were posted to jhild's previous post.

Unfortunately you left out any reference to the other kind of hole, or was that done on purpose?

The difference between and open hole and a cased hole is as follows;

an open hole is just that, the hole left by the drill bit

a cased hole is an open hole that has had cement poured into it, left to dry and redrilled with a smaller drill bit. This "casing" of cement prevents oil and gas vapors from leaking into other orizons. A production engineer can then tap into identified horizons he is interested in for production.
