We've never produced enough oil to sustain ourselves. We use about 19 to 20 million barrels per day. And only produce about 14 mbpd.
BULLSHYTE !!!
The USA has been drilling and producing petroleum for @ 165 years now. During most of that time we not only produced enough for our needs, but also to export. Only recent decades, and due to government~environment regulations/constraints have we had shortfall to demand, and that has been sporadic.
In World War Two we shipped millions of barrels of POL = Petrol, Oil, Lubricants around the world to our own militaries and those of many of our Allies. Just as one example. BTW, nearly all plastics and other synthetic materials are produced from petroleum.
Thanks for self-demonstrating the decline of American education, especially in science and history.
BTW "never produced enough" is either ignorance or a lie, but I suspect both apply in your case = ignorant liar

The
Drake Well is a 69.5-foot-deep (21.2 m)
oil well in
Cherrytree Township, Pennsylvania, the success of which sparked the first oil boom in the United States. The well is the centerpiece of the
Drake Well Museum located 3 miles (5 km) south of
Titusville.
Drilled by
Edwin Drake in 1859, along the banks of
Oil Creek, it is the first commercial oil well in the United States. Drake Well was listed on
National Register of Historic Places and designated a
National Historic Landmark in 1966. It was designated a
Historic Mechanical Engineering Landmark in 1979. The well was designated a
National Historic Chemical Landmark in 2009, on the
sesquicentennial of the strike.
The Drake Well is often referred to as the first commercial oil well, although that title is also claimed for wells in
Azerbaijan,
Ontario,
West Virginia,
Myanmar,
Persia,
Arabia,
Sichuan and
Poland.
In the United States before the Drake Well, oil-producing wells were wells that were drilled for salt brine, and produced oil and gas only as accidental byproducts. An intended drinking water well at
Oil Springs, Ontario found oil in 1858, a year before the Drake Well, but it had not been drilled for oil. Historians have noted that the importance of the Drake Well was not in being the first well to produce oil, but in attracting the first great wave of investment in oil drilling, refining, and marketing:
The importance of the Drake Well was in the fact that it caused prompt additional drilling, thus establishing a supply of petroleum in sufficient quantity to support business enterprises of magnitude.<a href="
