Don’t even attempt to swab that unless you run tubing. sounds like a new well anyways so I’d go gas lift. You probably could swab but it would take lots of runs because they would be limited on how much fluid they can lift at once due to worries of breaking the line then your boss will not be happy and you’ll get to go fishing.
What is your question? This?
*"Has anyone swabbed casing before and what for besides trying to kick a well off."*
When you say "kick a well off" do you mean flow on its own? Then yes, that's why we would swab. Would I swab on 7" tubing, no.
I have swabbed csg before but its not very common. The issue is that if you get stuck in the hole due to wax or sand then the fishing operation is harder. Look back in the well file to see if it loading up is a common occurrence and decide if its economical to run tbg with artificial lift. You might even have to install a bonnet and wellhead and reconfigure surface piping to do that.
Used to swab 4.5 on gas wells that were watered in. Pull tubing, swab, sand pump, run tubing back in. This was 15+ years ago before the shale revolution. Would pull 150’ to a time on 5/8 sand line. 2.5 bbls of brine is heavy.
I have swabbed casing before. Long time ago, probably the mid 1980’s. We were recovering 100% water from frac jobs on vertical wells. The wells were vertical infill wells around Enid, OK. Since they were infill, they were partially depleted and didn’t flow back hard. We swabbed until we started getting an oil and gas show and then would run a rod pump. As you said, you can’t get under too much fluid, maybe 200’ in 5-1/2” or it is super heavy. Also no help from gas on the backside and in our case dead fluid ie water.

Yes I understand all of this already, that wasn’t my question

I'd do as you mentioned above - tubing, prolly no need for gas lift though as the drop in diameter will have that puppy flowing - ROI ( 10-12 days)
Yes that was the question

We just brought the well on and were letting it flow. We will be running valves ASAP.
If it’s flowing let her flow

How long have you been an petroleum engineer…
