I wonder how much oil is consumed by the world in, say, a 1-hour
period (on average). Or even 1 minute...

Current consumption is something like 86 million barrels per day (86
mbpd). Divide by 24 and you get average hourly consumption of 3.583
mbpd. Divide further by 60 and you get average by-the-minute world
consumption of 59717 kbpd.

The USA alone, with 5% of the world's population, consumes about 25% of
these quantities.
