Motor and pump stuck in borewell

Hi,

Have a motor and pump stuck in a borewell and we tried fishing it out. It's caught on something and almost overturned a tractor that tried to pull it. Someone who is coming to repair it said they wanted to go in with a wire and lifebuoy soap to pull it out - I was wondering if you can help me figure out if this will work? Or if there are other mud chemicals you recommend?

Thank you
