I would think they are close to being done on the cleanout of the disposal well as they probably have been working on it for a couple of weeks. The drilling rig has been off of RU5A for about a month. I believe after that they are going to start drilling RU9. This is going to be a big month for Miller once they decide to start releasing news.
On-shore well completions are typically done with a work-over rig. Workover rigs will be used to place tubing, packers, plugs, etc. Perforations can be done off a workover rig or a mast truck positioned over the well head. The drilling rig typically will move on once the casing is set as their day rates are signifcantly higher than a workover rig.
Answer is yes , sort of ,in stages. The well must have comercially viable amounts of oil or gas.The completion would entail casing , well head being installed , and extration equipment to recover the product , and the establishment of flow rates.the rig is a heavy lift tower for everything(drill casing pipe,etc). The final completion is casing (pipe linings to strenghen the hold, well head = various pipes & valves to control flow, and in oil a pump( rocking horsehead /double weigthted pendulum ) that you see in fields) to extract the oil,natural gas is lighter than air so it would lift itself generally without an extractor.maybe google it "oil and gas well completion
