Oil question - anyone familiar with "swab rigs"?

Let's say we're 10K feet down already. Is a swab rig used to determine the flow rate?

But a swab rig is just used sticky for swabbing.

Come again?

A swab rig is often used in cased holes to pull fluid off formation. Most workover rigs have swab lines attached to them. When you treat a formation with acid or something similar often the perforations will be swabbed to see if they are productive. A strong formation might kick off and flow on its own after making a couple of swab runs (or might not need any swabbing), where a less productive zone might recover oil/gas after swabbing but needs a pumping unit to produce commercially. Sometimes perforations swab dry and are no good. Lots of these tight sands gas wells (i.e. Cotton Valley) will load up with water over time and need to be swabbed so that gas production will increase.

Exactly

The purpose of the swab is to pull fluid off the formation and/or out of the production string. This can be for many reasons. If a zone was just shot (perforated) and treated with acid you want to pull the "spun acid" off the formation and allow it to clean up. A new set of perforations might be swabbed to see if they have any indications of being productive before any treatment occurs. Older wells that are loaded up with water over time like tight sand gas wells can be swabbed to reduce the water head in the production string.

edit: I see where your previous question was answered.
