That was freaky... Earthquake?

[Strychnine]

They have 2 huge tanks that seperate oil in one tank and waste in the other. They then truck the waste to a seperate location where it's pumped back into the ground at injection wells. Am I right?

Definitely - no matter what method is used to extract oil and gas this process almost always also brings up water (brine) that needs to be disposed of, and some production processes like fracturing produce their own waste water as well. This water is taken to injection well or disposal well sites and put back in the ground.

You cant suck out all the lubricant from the earths plates and replace it with water and waste and not expect some friction.

But to say that oil is a lubricant for Earth's crust is fundamentally incorrect, as is thinking "replacing" oil with water is the cause. It's a planet not bearings in a small block chevy. Injection wells can cause issues when the rock formation they are injecting into is not sufficiently porous to allow the liquids to move quickly, which builds pressure. A frac job builds pressure with fluids, but the whole purpose is to do the job then remove the pressure (ie. remove the water) to allow the oil/gas to flow. The issue with some injection wells is the building of pressure on an existing fault over a period of time without release. The best analogy I've heard is that it's like an air hockey table. In some locales a waste water injection well is effectively like turning on the table and making the puck easier to slide.

The DFW quakes will likely be linked back to an injection well on or near the Balcones Fault which runs under Irving.

But in the mean time misinformation will spread like wildfire and "fracking" will be the catch-all scapegoat for everyone's friends on Facebook.

its god punishing the people of irving for tearing down his football stadium

Its kind of crazy to think that we (humans) have the ability to influence the movement of these massive and heavy plates.

Maybe it's fracking plus global warming?

One more quick note on fracing and quakes...

There is very little fracing going on in the DFW area now, as compared to the recent past. If it is causing these earthquakes, then areas down in the Eagle Ford area would be rumbling off the grid, as well as the Permian Basin (Midland - Odessa) areas.

Also, the average depth for a fracing job in DFW is ~ 5 - 8 thousand feet. These quakes are happening [on average] 3+ miles deep into the earths crust. Nearly 3 times the depth.

What are your thoughts on the studies that have been done that "definitively link" injection wells to earthquakes? The most recent by the guy from UT.

Im of the opinion that you could "definitively link" thunderstorms to earthquakes if you were so inclined.

Injection wells gave me the runny poops.

lmao..

i was in a meeting and just happend to move chairs to flip plans with my boss, i sat down as soon as everyone was like WTF was that? and im all like "WUT"? then i looked up and say the projector shakin like a mofo. i slept through the northridge 6.6 and missed this one. I'll prolly freak the F out when i do feel one

The Northridge was the first one I ever felt. I was in San Diego on the 8th floor and it shook my heavy sleeping ass awake. Felt a bunch of big ones out there in southern Cali when I was stationed there. Biggest was a 7.8 in the desert about 3 months before I moved to DFW.

I was at North Island when Northridge happened. We felt it.
Later that year, our squadron did a homeport change to Atsugi, Japan. First night there, we got woke up by what had to be one close to a 4. Not long after that, a 4 seemed barely noticeable.
