The oil deposits in US offshore fields are owned by the US federal government. The oil companies acquire a lease or the right to explore and produce from the offshore deposits. These are long term leases. Similarly, international offshore fields belong to the country that has legal right to the coastal waters. They may be lease by the country to private companies for exploration and production, but they may also be developed by the country's national oil company.

The simple answer is oil, like coal, was formed from ancient forrests that laid down millions of years of vegetation that for some reason (flooding, climate change, continental drift) stopped growing and were trapped into pockets that were covered by layers of rock and eventually pressed into coal fields and oil fields. Its not found everywhere because all the conditions needed for the process to work didn't exist everywhere. Oil is an interesting case. No one knows for sure how exactly it was created. You don't find vegetation fossils in oil like you do in coal beds and oil contains Helium, which is not used by plants. Physicist Tommy Gold (recently died) theorized that oil started as Methane (natural gas) ,which is the most common compound found in the universe, trapped in the earth when it was formed. The gas perculated up into a sub layer, like the water table, and was processed (eaten and crapped out) by microbes into oil. This sublayer of oil (estimated to be about 60 miles down) finds cracks above it, leading to pockets closer to the Earth's surface and slowly percolates up into these pockets, which we discover as oil fields. One way he suggested to test his theory was to revisit old pumped out oil fields and see if they had partially filled back up.
There are oil fields in many countries around the world. Some of the larger oil fields are found in Russia, Mexico, Brazil, Kazakhstan, and Venezuela. Oil fields are also found in the Middle East in countries such as Kuwait, Iran, and Saudi Arabia.
There are oil fields as well as gas fields located in the state of Oregon.
Oil Fields
The Hibernia oil field was developed to extract oil reserves located beneath the seabed of the North Atlantic Ocean off the coast of Newfoundland, Canada. The discovery of significant oil reserves in the area made it economically viable to establish the oil field for extraction.

Sour Lake Oil Fields - 1904 was released on: USA: 1904
Most of the oil fields are located in the North Sea. Norway, the Netherlands, the United Kingdom, & Denmark pump oil from them.
It depends specifically on the country. Iran nationalized its oil fields in 1953 and then again in 1979 (since they had returned to the British in 1954). Egypt nationalized its oil fields in the 1960s. Saudi Arabia has nationalized some oil fields and created profit-sharing agreements on others from the 1970s onwards.
