Key key word is proven (actually should be called "proved")
Oil is not allowed in the proved reserves column until it is drilled and flow tested.
By keeping large areas not available from exploration and production, he artificially lowers the amount of the actual oil in the ground to be counted as proved reserves.
Another lefty claim is that ‘big oil’ has many wells that are proven, but capped, sitting on them while the price goes ever upward. Thoughts?
