The first oil well in the U.S. was drilled in 1859. Do you know where?

Titusville, Pennsylvania. While historical records indicate that naturally occurring seeps of petroleum were collected and used for a variety of purposes as early as the 1600s, Colonel Edwin Drake was the first to devise a mechanical system to drill into underground reservoirs and secure sufficient quantities of petroleum to make it commercially marketable.

What was the first commercially marketed use of petroleum in the U.S.?

Medicine.  Early settlers of northwestern Pennsylvania skimmed petroleum from streams and used it medicinally.  Impressed by the apparent benefits of petroleum as a medicine, about 1849, Samuel Kier, a shipper and merchant, began bottling the petroleum he collected from salt wells on his father’s land and marketed it as a cure for all sorts of human and animal ailments.

What is the greatest source of crude oil and petroleum products found in U.S. waters?

The vast majority (63%) of petroleum found floating in oceans, rivers, streams, and lakes comes from oil seeping naturally out of the ocean floor, lake beds, and the land.  Spills caused by petroleum users such as improperly discarded motor oil, gasoline spilled during fueling, leaky petroleum storage tanks, and even fuel leaking from pleasure boat engines are responsible for about 33% of petroleum in U.S. waters.  Only 4% of oil spills result from the exploration, production and transportation of crude oil and refined petroleum products. Data are for 1990-1999.
