how do you find oil

It is extremely challenging to find oil. the people who dig up oil have only a 30% chance of striking it. Today in red class we did an experiment to see if we could find oil. Mrs. N taught us what we need to look for before we dig. Our group did a poor job of that because we didn't get any oil and our company went bankrupt. Today humans are running out of oil and oil is a nonrenewable resource. That means if we run out of we don't get anymore. It takes millions of years for oil to form.
