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.
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.
This is impossible to know because not all wells have to be permitted. It is in the millions though.
Depends...First all oil wells are rated in barrels (42 gal).Some wells can produce hundreds of barrels of fluid per day. Some wells produce only one or less than 1 barrel of fluid per day.The fluid they produce can also vary in the amount of oil they produce, some wells might produce a lot of fluid but its only 5% oil where the rest is salt water. While other wells produce pure oil and all in between. Some wells even actually inject fluids back down into the geological formation. Not every well you see is a producer.You might have two wells 50' apart and they produce completely different amounts of oil. It all depends on the geology down where they drilled and luck since you really never know what is down there until you drill the hole.
Texas, also known as the Lonestar State, is most famous for cattle ranches and oil wells/industry.

Oil wells do not refill themselves. Oil is a non-renewable resource that forms over millions of years from the remains of organic matter. Once an oil well is depleted, it will not produce more oil unless new deposits are discovered and drilled. The process of oil formation is slow and cannot keep up with the rate at which humans consume oil.
