Despite advances smart pigs aren’t terribly accurate. Pipeline operations have to shut down and analyzing the data smart pigs gather can take some time

Who could have ever imagined that North America would surpass Saudi Arabia as the world’s largest producer of oil and natural gas liquids? A decade ago, that would have seemed laughable.
