The primary environmental residue of dry ice blasting is the sublimed CO2, thus making it a useful technique where residues from other blasting techniques are undesirable.
the dry ice formed causes the water to freeze, forming an ice plug, allowing them to do repairs without turning off the water mains.

My solution would be to create a pipe thats just a few inches smaller than the diameter of the oil pipeline now this pipe is actually two pipes one inside another and have the outer pipe be made of some flexible material that can hold air or hydrolic pressure, insert it into the leak as far as you can get it in and then inflate the pipe and extract as much as you can till the well runs dry then pull pipe out cover everything over with cement and get the heck out of dodge.
