18,300kg methane per hour * 24 hours * 365 days = 160,308,000kg (~0.160 million metric tonnes).
At 25x CO2 equivalent, that is 4,007,700,000kg (4 million metric tonnes).
4 / 767 ~= 0.5%, so in the ballpark of the parent comment.
Also possibly the second link is ton (~1016kg) vs tonne (1000kg), further tweaking the numbers.
And just about the Permian basin, Wikipedia says it "accounts for 20% of US crude oil production and 7% of US dry natural gas production" - https://en.wikipedia.org/wiki/Permian_Basin_(North_America)#...
So if all sites like this were measured, it might be more like 2.5% coal-use-equivalent?
Where do you get the 25x from? Wikipedia says it's 80x-100x:
> over a 20-year period, [methane] traps 84 times more heat per mass unit than carbon dioxide (CO2) and 105 times the effect when accounting for aerosol interactions
After that 20 years, methane decomposes into CO2 so its long-term contribution is 3x CO2 equivalent (due to the higher mass after acquiring the oxygen atoms), so its lifetime CO2 equivalence can be higher or lower than 25x depending on which timescale you're looking at. Is the 25x an oft-used figure in the industry/literature?
The 100 year global warming potential seems to be a pretty common way to compare greenhouse gases. It makes sense when you discuss things like, say, limiting warming to N degrees by 2100 or long-term climate change, but I agree that the caveat that "it's much, much, much worse on shorter time scales" should be emphasized way more than it is. Especially given the current situation.
HN'ers seething - you can't beat cheap fossil fuels for base load capacity (ask Germany)
Only thing that trumps fossil fuels is nuclear - instead of the EU chasing Apple over USB-C ports, why don't they come up with some subsidies for better reactor designs?

This link about US electricity generation: https://www.eia.gov/tools/faqs/faq.php?id=74&t=11 shows 767 "million metric tons" from coal, or 1.55 "billion metric tons" from all sources.
