Little workover rig. Looks like they are pulling 30 ft singles. Probably a shallow completion. I can't quite make out the signage on the equipment on the right side of the photo. That might be a clue to what they are doing.

That is a Capstar rig, at least Capstar seems to have a monopoly on them. They have a pick-up arm for the drill pipe and a top drive, I have gone to 6000' with one.
