It’s unlikely that anyone is plugging a well producing 10 barrels of oil a day in today’s price environment.
However, re-entering a well which MIGHT be capable of producing that much is going to cost probably around $300,000. Of course, you’re going to have to pay a royalty percentage to the landowner for every barrel you produce, plus pay severance, ad valorem, and income tax for every barrel.
Then you’re going have to pay a fee to someone to pick up those barrels and take them to a refinery. That’s after you pay to install tanks near the wellhead to store the oil that is produced because trucks won’t be lining up every minute to pick up the next quart of crude you bring to the surface.
