Norway is a significant oil producer and exporter, worthy of mention together with Saudi Arabia in the context of discussing oil producers (potentially) exporting crude oil to the US; not Sweden. Norway was in a (forced) union of kingdoms with Sweden until 1906, so someone referring to Sweden as an oil producer may only be somewhat right if 1906 had not happened. hth
The U.S. Energy Information Administration says Sweden has produced 8.4 thousand barrels per day since 2010.
Tiny, but non-zero (they remain heavily reliant on oil imports from Russia).
Also, Lundin Petroleum is a Swedish oil extraction company, which extracts oil off the Norwegian coast. https://en.wikipedia.org/wiki/Lundin_Petroleum
And Sweden does have onshore oil deposits that have not been opened for extraction - https://sputniknews.com/business/201703071051330296-sweden-o...
Note that dorfsmay didn't say "oil extracted in Sweden", you added that qualifier yourself. He also indicated his example may be weak on details, whereas you were explicitly striving for accuracy.
The only operational, limited extraction of oil in Sweden took place in Gotland, until 1993. The remnants of that activity have now become historical markers. The Swedish government agency of statistics reported in 2016 that there is absolutely no production of crude oil in Sweden ("I Sverige sker ingen produktion av råolja."). [1] Who should we trust on this, the U.S. Energy Information Administration, or the Swedish government?
Not sure why all of this is so arresting.
