Not a credible study, since it starts with the global warming agenda,
notably, this:
"Further, IEA warned that in order to limit global warming to 2C above pre-industrial levels the generally accepted target to stabilize carbon emissions and avoid dangerous climate change no more than one-third of the worlds remaining proven fossil fuel reserves can be burned, and massive global investments in energy efficiency and low-carbon energy technologies will be needed."

Then, the "study" goes on to do comparisons between current oil production and "expected" future production between the U.S. and Saudi Arabia.
The study didn't go deep into the production which is easily available if the government would get out of the way and allow the oil and gas and coal industries to drill and dig out those resources. We can, for certain and for the long future, be energy independent. But, we won't ever be energy independent if the environmental agenda continues to stifle the search for that independence.
That study ain't worth the bits it took to display it on the screen.
