USGS Report: Link Between Fracking and Oklahoma Earthquakes, page 1

Link to the article.

I know, I know it's unbelievable right?

Who could ever have imagined that using highly pressurized fluid injection into the earths crust in order to create or enlarge fractures within it could possibly have a negative impact on the stability of the earth's crust?

Description of the fracking process.

OK, no more sarcasm... but in all seriousness, how many little brown envelopes had to change hands in order for an idea with so much obvious potential for disastrous consequences be allowed to continue?

the United States Geological Survey has released a report that links a series of earthquakes in Oklahoma last January to a fracking operation underway there... Our analysis showed that shortly after hydraulic fracturing began small earthquakes started occurring, and more than 50 were identified, of which 43 were large enough to be located.

Cuadrilla Resources, a British energy company, recently admitted that its hydraulic fracturing operations “likely” caused an earthquake in England.

Of course, humankind has such a great track record of tampering with nature without any negative consequences. (Oops, sorry, I said no more sarcasm!)

ok i have seen a lot of threads about fracking and i have some questions. how high of pressure are they using to push the fluid in the ground? when u inject the fluid under ground, how big of an aria does it affect under ground and on the surface when the crust shifts casing an earthquake?

just a few questions i keep thinking about wondering if this earthquake was caused by a mining or if it is something naturally o curing

Fracturing equipment operates over a range of pressures and injection rates, and can reach up to 100 MPa (15,000 psi) and 265 L/s (100 barrels per minute).

While hydraulic fracturing is many times performed in vertical wells, today it is more often performed in horizontal wells. Horizontal drilling involves wellbores where the terminal drillhole is completed as a 'lateral' that extends parallel with the rock layer containing the substance to be extracted. For example, laterals extend 1,500 to 5,000 feet in the Barnett Shale basin. In contrast, a vertical well only accesses the thickness of the rock layer, typically 50–300 feet.

It was a very shallow EQK and I asked if there was any fracking going on in the area at the time of the EQK.......no one replied.

It appears fracking could had caused it and I believe this was the case.

This link is an apparent government report confirm the earthquakes are caused by this forced injection technique.

Hundreds of scientists would beg to differ.

It seems that you are assuming that the process of fracking creates vibrations being mistaken as earthquakes, somewhat like feeling your house shake because of road work nearby.

This is not the correlation that has been found by this USGS study, among many others.

Here goes:

1) The fracking process is undertaken, causing physical fractures and structural weakening in the earth's crust.
2) Time elapses.
3) The earth adjusts to this fracturing with a displacement which is both measured with a seismograph and felt as a "shaking" on the surface, commonly known as an earthquake.

The research has found a possible correlation between these two events.

Even though massive influence from the industry has ensured that the contrary view is more heavily influential when asking politicians for the rights to operate.

Still think this is hogwash?

As I stated in my OP, even the least educated layman could foresee that a process involving high pressure injections into the earth to create and provoke structural fracturing within it could potentially lead to dire consequences.
