Do you know the best and most popular oil companies in the US?

One of the largest industries in the USA is oil production. The oil and gas industry has, to date, been responsible for major innovations in how humans produce and burn fossil fuels, as well as new methods of extracting previously unreachable deposits of oil and gas.

There are over 20,000 oil and natural gas companies in the US. In 2018, the industry produced over 5 billion barrels of oil, while employing nearly 985,000 people. The biggest American oil companies produce billions of barrels of crude each year — and employ tens of thousands of people across the country.

Why does it matter? Because understanding where our energy comes from is crucial to understanding why it costs what it does.

Without further ado, let me introduce you to the list of oil companies in the US:

  1. My name is David Crorey retired after 35 years in the Automation/Robotics industry. I am an inventor with more than 50 Patents. I know the government is pushing electric cars and the one drawback is time to recharge on trips and charging stations everywhere. My solution to this problem is to make a quick-change common Battery. Every gas station would have charged batteries in a changing station. Would pull your vehicle to a changing location you put in your CC from your car and in second your battery would automatically be exchanged from under the vehicle with a fully charged battery. Click Click and you would be on your way.
    This would require the government to mandate a common battery size for all automotive companies. This would also be a good thing for service/gas stations and eliminate the need for charging stations. The cost we be on the service stations and car manufacturers not on the tax payers.
