Nobody that I've ever met in the industry believes this theory. We wouldn't plug wells if we did.
However, anyone who wants to purchase a well that we're about to plug is welcome to freepmail me. The buyer can then watch and wait for the well to magically refill.
I think you are speaking to a strawman version of the theory. The theory is that if the oil is formed much deeper in the crust than we currently think, the oil fields we access today are the result of "leaks" from that larger resevoir. Leaks which could only take place under certain conditions. Some fields would be replenished, but most would not, having been "cut off" from their original source by geologic activty. There is also the issue of the speed of "refill" of those fields that do still have some commnection to the deeper resevoir.
I'm not saying Gold is correct, just that his theories may be being misrepresented and/or oversimplified.
