Question : What material is used for freeze tapping, a procedure used to replace valves in an oil or gas well.?
The process I am wondering is called freeze tapping, a safe and economically sound way to replace #1 2 3 main valves in an oil or gas well. The procedure entails injecting a slimy substance into the well and freeze it by injecting liquid nitrogen. Once the substance freezes it creates a sealed layer that prevents the well from blowing up with the underground pressure. Please tell me if there is any manufacturer of such substance or what the substance is called.
call tapping
