I read an article about Alberta, Canada losing millions per day from air barrels and am now doing some research, but having a hard time finding information.
I am curious to know more about air barrels and why they occur. Are there better systems out there that prevent air barrels or is it a constant, inevitable issue for pipelines? In particular, I am interested in the economics that result in air barrels, as well as the infrastructural issues or limitations that companies use to justify the purchase of air barrels. If you happen to know anything else about them, please do tell.
