Study Says Fracking is Safe In Theory But Often Not In Practice

First time accepted submitter chadenright writes "A university study asserts that the problems caused by the gas extraction process known as hydraulic fracturing, or 'fracking,' arise because drilling operations aren't doing it right. The process itself isn't to blame, according to the study, released today by the Energy Institute at the University of Texas at Austin."

I ask this because every other investigation I have seen all have the same thing in common: Putting about 3000 different chemicals (mostly very toxic) into the ground is a mayor threat to drinkingwater and should never ever be repeated again.

      I am on a different side of it.

      It *sounds* bad to be putting 3000 different chemicals into the ground until you actually start taking geology into account. Having been on-site and spoken with engineers, I am *EXTREMELY* dubious that when fraccing zones more than 10,000 feet underground that it can affect the water table thousands of feet above it.

      Especially Texas where most of the wells I am aware of are deep wells.

      Plus, fraccing is required when the permeability of your zone is low. That means, by definition, it would not be a water table or any other kind of zone in which those chemicals could be moving around. If it is that permeable already and connected to a water table you would be tasting the natural hydrocarbons already.

      I have always brought this up when these types of articles appear that the very definition of the technology would seem to preclude these types of interactions with water tables.

      This study only seems to confirm what I was already saying. Only wells that are improperly fracced have these kinds of results.

      Now I can certainly see that horizontal shallow drilling accompanied by fraccing could possibly introduce the natural hydrocarbons (that were trapped in various formations) into water tables along with the fraccing fluid.

      The mistake people make is thinking that the ground is the same the whole way down. Far from it. It's more complicated than that. If water tables are being affected it is because the engineers are idiots and not doing it right.

      The study is entirely plausible. It says it works in theory (which it most certainly does) but in practice you can fuck up and contaminate the water tables. Doesn't tell me something I did not already know intuitively.

      That sound great, until you realise that by frac'ing and drilling into the rock, they've changed the permeability of the rock (ie: the point of frac'ing).

      Drilling does not change the permeability of the surrounding rock. Keep in mind there is something called well casing which essentially protects the hole all the way to the surface.

      If you drill a hole in concrete and fill it with water, did it make all of the concrete more permeable? Nope.

      Many of the chemicals are water soluble and/or are lighter than the ground water, why wouldn't the ground water seep down in the now permeable rock and mix with the chemicals?

      The ground water would not seep down because all of the rock formation did not have a uniform increase in permeability. It was like a bunch of cracks in a concrete wall that was further separated from the water table (we will just say a layer of dirt) by another layer of concrete that was unaffected by the frac.

      Imagine this.

      You have a mix of concrete in which you suspended bubbles of Coke. It is 100 feet thick. You then have a layer of normal concrete that is 1000 feet thick. On top of that you have a 100 foot layer of dirt that has a bunch of water in it.

      The water table is only going to extend to the concrete itself, and not all the way to the bottom. That's the way they work, otherwise water could just fall all the way to the core of the Earth.

      You then drill a hole through the whole thing. Before you frac, or do anything else after drilling the hole, you make a nice reinforced straw. That is called casing. All of the dirt does not directly interact with any fluid in the hole. It can't. The casing is there.

      The water table is protected by the casing.

      Now you perforate the casing all the way at the bottom with shaped explosives. This allows the Coke to flow into the hole under pressure and go to the surface. However, since the permeability is so low... you are not getting a lot. The Coke does not interact with the water table due to the casing.

      That's where fraccing comes in. You create thousands of small fractures (hence the name) in the bottom layer with that nasty fluid everyone hates. Pump in proppant (which is like sand) and remove the fluid.

      Now what you have is a bunch of fractures that allow the trapped Coke to travel to the hole faster. That's why it is done.

      The fractures themselves extend out horizontally some distance, and vertically, but they they simply don't make it all the way through that 1000 foot thick layer of concrete to get to the water table above it.

      That is why ground water does not seep into fractured formations thousands of feet below it. A path does not exist.

      So now that you understand that, the only way the water table can be affected is with damaged casing (has nothing to do with fraccing) or a fraccing process that put the water table at risk because it was too close.

      That's why the technology is perfectly fine in theory. Any dickhead that decides to do something like that too close to water table is the real problem.

      Companies are simply making guesstimates of what will happen when they pressurise formation and, where the fractures will go and how it will affect ground water at various depths.

      Here's how it works for people looking for water. They drill down a bore into likely areas, and when water flows, they test the suitability of water derived from that formation, they keep drilling till they find a suitable formation to draw water from or the reach the depth level of the equipment or they run out of money or they give up and try at another location.

      Eventually they mostly find a safe suitable source. Now along comes the fracking company, they purposefully introduce largely random (the lack the ability to 'accurately define where the fractures will occur) stress fractures in the rock, the purpose to specifically allow the mixing of fluid and gas materials to mix at various levels, basically turn rock formations into massive soda fountains. Will it affect nearby wells, they don't know and they don't give a fuck.

      So there is at least one path for contamination.

      No. There is no path with proper well casing.

      Additionally, frakking is the process of breaking geological formations in order to allow for the collection and extraction of liquid petroleum and gasses, AND a direct correlation has been show between frakking and increased geological activity.

      So, they are intentionally breaking the layers of rock separating pockets of gas and oil, and causing small earthquakes.

      Extremely small earth quakes. It is misleading to give it that term because it implies to most lay people that you could feel it long distances away. You can't. Unlike the vast majority of posters I have been less than 100 feet away from the well bore in a trailer when a large frac was performed. I did not fall down, and other than a light amount of vibration, it was just a big bang. Also keep in mind, that any release of energy that high would require some impressive engineering on the well bore and drilling rig.

      I would like to see studies that show a direct correlation between fraccing and increased geological activity. "Correlation does not imply causation". While I don't wish to seem like I am resistant to the truth, the science behind fraccing does not, at a glance, support sustained increases in geological activity.

      Citation please.

      Meanwhile you are arguing that "it is impossible for the technology to cause the problems", and that there is no way that during all of the intentional layer breaking they might cause something to change in the layers that are sitting on top of the work area

      They can't cause any large scale or meaningful changes in layers sitting on top of the work area. I am assuming that you mean that a frac conducted at 15k feet deep can change layers between a thousand feet and the surface. That would not happen.

      In order for it to be true, the energies required would be impressive to say the least. The frac would not be limited to the production zone, but would result in fractures at the surface. Such energies would result in an earth quake comparable to a nuclear blast. You would feel that in major cities hundreds of miles away.

      You simply cannot affect changes through that many thousands of feet of rock without the requisite increase in energy levels. It's not like they are bringing out portable nuclear power on site. It's diesel man.

      Additionally, and so many people here overlook this, for every fracture that is created you need to pump proppant into it. This means you can tell how well your frac performed, in part, by looking at how much proppant was pumped into it. To have large scale effects at the water table, thousands of feet above your target, would require many many times the amount of proppant you estimated was required. You would know.

      I'm not sure that "impossible" is the right term to use. I'd have chosen "marginally unlikely", but that's just me.

Any fluid remaining was extracted over time to a container on the site. I remember that for a few years a truck had to come by every so often to empty it. What I witnessed had practically no impact on the local environment at all. No ponds, fluids, etc. Just a well bore, casing, and a pipeline to take the natural gas to the refinery. That's it.
