Since the first known oil wells were drilled more than 1660 years ago, it might be possible to answer this question with a crew of 100 scientists, with 10 years each of spare time, a load of motivation and a few million Dollars in funding.. :D
They're both different in many ways but similar in some.
Into the aquifer
Oil is produced by wells. Oil wells are drilled on land and offshore in locations likely to contain oil.
Fracking is when a high pressure solution of water, acids, etc. is injected deep into a drill hole (usually horizontally drilled not vertically drilled) with the intention of causing fracturing of the rock layers around the hole, allowing trapped oil and gas to escape from that rock and collect in the drill hole. This causes a significant increase in well production and in many cases can transform a "worked out" field of dry wells into a valuable actively producing field again. Unfortunately sometimes the fractures enter aquifers polluting the water in wells depending on that aquifer.
Surface water is from wells to about 30 ft deep. Drilled wells deeper than 30 ft are not surface water.
All 77 counties in Oklahoma have had oil wells drilled in them.
According to the North Dakota Industrial Commission, Department of Mineral Resources, Oil and Gas Division, as of January 2015, there are a total of 12,182 producing oil wells in North Dakota with a total of 13,657 wells capable of producing oil.
This question is impossible to answer, as wells are being drilled continuously.

false.
The first oil wells were drilled in China in 347 A.D. using bamboo poles. In Persia hand dug wells reached depths of 115 feet in 1594. The first modern well was drilled in Russia in 1848, and in 1859 Colonel Edwin Drake drilled the first US oil well for commercial oil production, at Titusville, PA; it was 69 feet deep.
