Hansard (pdf) has a transcript of Dr James Buckee's testimony to the Australian Senate inquiry into public transport funding (via Energy Bulletin).

I have had 37 years in the oil industry. I was CEO of a large company for the last 16 years and I have just retired. As Bruce pointed out, that company produced about half a million barrels a day, which is sort of Australia’s consumption. From the 16 years of exploring the world, I would make the following observations: there are virtually no unexplored basins in the world. The ones that there are might be in the Arctic, and that illustrates the point quite neatly because it is obviously really difficult to get that.

The underlying fact here is that the world is consuming 30 billion barrels of oil a year and finding eight. It has been like that since 1980, maybe a little bit earlier, and it is certainly not getting any better. There are two further things. People say, ‘Look at the subsalt discoveries in the Gulf of Mexico and Brazil.’ I would say, those are extremely difficult resources to produce. You will notice, of all the discoveries in the deep water Gulf of Mexico, not one barrel has been produced; not even on the list. It is the same for Brazil: it is subsalt and it is really difficult to produce.

The second point is that—I agree with the gentlemen over there—the black oil has peaked. This is disguised by the NGL production from the big gas fields in Qatar. They are quite rich in liquids and, as the LNG has been boosted from there, so has the associated NGL. So that has enabled the world’s liquids to keep growing, albeit slowly, while the black oil itself has declined, and this is disguised.
