READ your own charts
and read about the Saudi oil price war
en.wikipedia.org
and if I remember right I already apologized for saying Billions and explained it was Millions of barrels a day
YOUR own chart shows in May and June 2020 we were importing 11.5 to 12.5 Million barrels a day from the Saudi's
and IF you paid attention you would have seen US production went down to the mid 9MBPD then and I have shown and am not going to go back and dig it up but over 100 US oil companies went Bankrupt and a lot of them went out of business and never came back
and as shown in one of your charts US oil production went down to 9,7 MBPD in Feb 2021 and is now back up to where it was in 2020
Have a nice night
