VDH is no scholar when it comes to this issue, or he wouldn't have ignored all the studies that show how wrong he is.
Here's another excerpt from the Science Direct article I linked...

1. Introduction
While the world's attention and policy initiatives have been on climate change, including the role of oil in contributing to this, a potentially equally important issue has continued in the background - the world's relentless depletion of its reservoirs of oil. In this paper we ask: ‘How much oil is left to produce?’, and hence determine if we are likely to face soon a global shortage of oil.
Below we show that official estimates of the remaining reserves of oil as used by many analysts are very misleading, in part due to poor reporting and methodology, and that these reserves data should not be used. We also show that the basic Hubbert logic of oil production, that of increase, then peak (or peaks) and then decline, is playing out relentlessly (if not exactly) for nearly all oil producing countries. While dismissal of Hubbert logic by economists, with faith in technology to increase oil production, has been seemingly supported by the fracking revolution of the last decade and a half, this had little impact on the longer-range inevitability of oil depletion driven by global resource limits. Analyses by others and ourselves of the patterns in the global discovery and production of oil show that the world's rate of use of oil has long been much greater than its rate of finding oil, and hence the future global production of oil at prices that are sustainable to society is inevitably downward.
