I'm seeing vastly different numbers reported for Saudi Arabia's oil & gas share in GDP. One Saudi scholar gives
Kingdom of Saudi Arabia owns 17% proven reserves of the world and constitutes 50% of the Saudi GDP, approximately (Saudi Arabia facts and figures, 2020).
which is sourced from OPEC... which indeed said that then.
The oil and gas sector accounts for about 50 per cent of gross domestic product, and about 70 per cent of export earnings.
Crude petroleum and natural gas activities achieved the highest contribution to GDP with 27.4%
They do also account for some other 7% of the GDP due to "Petroleum Refining". (Alas, I'm not sure how to get 2020 version of the official Saudi data.)
So, did Saudi Arabia cut in half its share of oil and gas GDP share from 2020 to 2022? I find this hard to believe given that the oil price in 2020 wasn't any higher than in 2022 (in fact it had a huge dip in 2020, due to the pandemic.) What alternative explanations exist for this rather large difference reported, e.g. in terms of how that share of oil and gas in GDP is computed?
(Before some suggests I ask this on Skeptics, it's not suitable, because it's not a single claim based on just one source.)
