Fracking originally started in the 1940s. There is no known distance that s for sure on how far fracking wells go. It is basically that they go down as far as they need to to get oil out of a well underground.
You probably mean Tannin. And there is normally no tannin in deep wells. Only in shallow wells.
Most home wells are about 50 feet deep.
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.

Fracking is a new method for extracting natural gas from shale rocks. Wells are drilled down to these and then heavy mud injected to hydraulically fracture the shale rocks. The fractures release the gas trapped in the rocks which is then extracted at thew well head.
Oil well are 2000 to 3000 ft deep.
Depends, but usually they are 10,000 ft deep.
The fracking process you are speaking of are taking place all over the country. Most take place on people back yards.
Fracking is done all over the world.
Fracking is a way of obtaining gas from rocks underground
No. Fracking can cause earthquakes if the fluid gets into faults. Tornadoes are caused by thunderstorms, which are not affected by fracking in any way.
