The dollar depends to almost no extent on foreign oil sales. Global oil demand is 100 million barrels per month [1]. At $80/barrel that’s about $100 billion a year. We import over $300 billion a month [2]. That’s $3.6 trillion in foreign wallets a year looking for a way to be spent or invested. That’s why the dollar is dominant. Not how Ghana buys oil.
I don't buy the more elaborate version of "petrodollar" theories myself, but your first link says "Global liquids demand declined in October to 99.6 MMb/d". That's per day, not per month, so at $80/barrel it would be about $2.9 trillion per year in global oil sales.
