I have seen with my own eyes raw crude being pumped out of a open ended pipe into ponds dug into the ground in Baku, gas being burned of in quantities that you would not believe because its not profitable to either re-inject it into the well or transport ashore and sell.
The list goes on and on, but its not only oil companies, even the likes of Coca cola are at it.
