Some auto parts places sell nut-splitter tools, but you may not have enough clearance to slip one over the nut due to the oil pan. Do a web search for the tool and take a look.
Take the bolt into Advance Auto, explain the problem, then ask them if they would recommend a Heli-coil fix.
drill it and use an “easy-out”.
recut the threads and install a new screw.
I recommend an o-ring...just to make sure.
Get a hacksaw blade and go to work! Saw down one side then pry it loose with the screwdriver.

Also, a stack of thin washers cut “open” into a “C” shape might be tapped behind the nut. Stack them one at a time until the threads grab.
“Oil boogers”?
You need to see a doctor, man.
Machinist’s trick....get another 10mm nut that fits on the stud...run the new nut down to the old nut...tighten the two nuts against each other, locking both onto the stud...this will give you leverage on the nuts to back or pull the stud out.
Most likely the threads in the engine block, or on the stud, are stripped. Is the block aluminum? If so it’s those threads most likely stripped.
Studs don’t drill out very good. Best to grind the stud/nut off.
When you get the stud out of the block it will require a thread repair of some sort. Tap to larger size or a heli-coil repair.
Get a small (1/2 in or so) triangular file from HD. Lay it flat against the nut and file lightly around the bolt.
Then the nut will start out on the threads with your grips.
Watch alignment and you won’t hurt the bolt.
a triangular file is great for light repairs to threads.
I'm confused. What are the 'two' nuts for? If they don't hold up the pan what do they do?
Good luck.
If the nut and stud is stainless steel it’s probably galled. You need to use some sort of anti-seize on stainless.
Does the stud thread into the block...could tack weld nut to stud and essentially turn it into a bolt and back out.
If not, could you take off all other pan bolts and pry between the pan and block to put downward force on nut while you try to back it off.
$50 inverter for AC tools ... drill the sucker out and quit playin’ with it.
Tack weld the nut to the stud and if you do it right you can turn the whole stud out with a socket or wrench.
This is common practice.
Some times you can weld a spare bolt or nut to the end of the stud.
Helicoil or a nut-splitter.
Smart ass ... but best laugh I’ve had all day. Thanks!
I agree...Something to get between the pan and the block and force the pan to the bolt while you try to turn it...Have used that procedure on countless numbers of bolts...
