For the oil experts, or anyone with knowledge:

[Obamaknowzz]

What is the maximum diameter solid pipe that could be forced down this oil pipe with the high pressure as it is. There was a 4" pipe used as a siphon. My idea is based on the use of an expansion bolt either expanded with a screw or a controlled blast, that could be shoved into the pipe.

Thanks
