Stabilizer:

A tool placed on a drill collar near the bit that is used, depending on where it is placed, either to maintain a particular hole angle or to change the angle by controlling the location of the contact point between the hole and the collars.

See packed-hole assembly.

2.

A vessel in which hydrocarbon vapors are separated from liquids.

3.
