Here is a quote,
“As a result of the shale boom, the US is the world’s largest oil producer, with output expected to average 12.4 million barrels a day this year and 13.3 million barrels a day in 2020. Likewise, America is the world’s largest producer of natural gas, producing an average of 91.3 billion cubic feet of LNG a day this year and 92.7 billion cubic feet a day in 2020.”

Here is from President Trump 23 minutes ago.
“Because we have done so well with Energy over the last few years (thank you, Mr. President!), we are a net Energy Exporter, & now the Number One Energy Producer in the World. We dont need Middle Eastern Oil & Gas, & in fact have very few tankers there, but will help our Allies!”
