There are about 950000 oil wells in the entire world. Of those, 530000 are located in the US!
The US still produces a lot of oil, especially in Alaska and Texas. But we use more oil that we produce so we have to import oil from other countries such as Saudi Arabia and Mexico. In the US, oil companies are still looking for other wells with oil to replace the wells where all the oil has been recovered.

I dont mean to be mean but USA leads in producing dead corpses in other countries where they have large oil wells.
There are almost 4,000 oil rigs in the U.S. 79 are deep water wells.

Alaska by far.
Saudi Arabia is producing a lot of oil because it has large oil reserves. Saudi Arabia has one of the largest oil reserves in the world, and producing enough oil to trade to other countries, mainly the US, is very profitable for Saudi Arabia.
I have provided an answer based on my assumption that you would like to know how much oil a well produces on a daily basis. It is very hard to generalize. Oil production is measured in barrels per day. A barrel is 42 gallons. Well production is highly variable and depends on many factors. There are many wells in the US producing less than 10 barrels of oil per day and are considered "stripper wells." The high side of oil production from a single wellbore can be as high as 10,000 barrels/day. The production normally declines as reservoir pressure declines. An increase in gas and/or water can result in declining production.
After Iraq invaded Kuwait in 1991, the US developed a plan to force the Iraqi armies out of this small oil producing country. The Operation Desert Storm was a US led coalition that used US airpower, then ground troops to end the Iraqi occupation. The Iraqi's set many oil wells on fire as they retreated and some of these fires lasted for weeks and weeks. Casualties in this operation were not large and the war ended rather quickly.
This question is impossible to answer, as wells are being drilled continuously.
Yes. North Dakota is now (2011) the 4th largest producer of petroleum in the US.
