I listened to the skeptiod podcast and love your program. I listened to your episode on fracking and helped reduce if not dispel my concerns over fracking and drinking water. However I'm now wondering about a supposition I've heard that fracking in the UKmay have triggered earthquakes there. My understanding there was an investigation and the report said that it is "highly probably" that was the cause. I'd love to hear your analysis of this Brian.
 
A couple thoughts: The really big and destructive earthquakes, like the recent one in Japan, are caused by plate tectonics. Fracking does not cause these. It's possible that it could trigger smaller earthquakes, but these may be earthquakes that would have occurred eventually anyway. In fact, small earthquakes are sort of a good thing because they release energy that was building up and would eventually cause a large destructive earthquake. Maybe tens or hundreds of years in the future, but eventually. Just like it's better to release water from a dam a little bit at a time than for the dam to fail and release it all at once.
 
The conditions in Oklahoma are a bit complicated.
The tallest building under construction in Oklahoma City is being built by Chesapeake Energy which does a lot of fracking to get natural gas.

There are a lot of independents frackers who just shove a lot of diesel fuel into the shale to frack it. Yes, straight out of the truck diesel fuel.

The Oklahoma Governor Mary Fallin is a republican.

The damage to roads in the vicinity was repaired immediately by ODOT (so the fracking trucks could leave the scene of the crime?)

After the last 4.7 had me surfing in my living room, I sent a nasty gram to the Governor.

I plotted out this page from the U.S. Geological survey up to the 4.7 on Nov8 . I threw out the Arkansas data.
http://earthquake.usgs.gov/earthquakes/recenteqsus/Maps/US10/32.42.-100.-90_eqs.php

It appears to have one distinct loci and a much larger perimeter. It appears to be a rough oval shape about 20 miles E-W by about 12 miles N-S. The one loci is nearly centered on the location of the 5.6 earthquake. The perimeter appears to move to the West.

The first 12 earthquakes stay close to the loci and then they start setting a perimeter to the west with the 3.8 on 6 Nov.

You can use excel to convert lat and long to distance. I used the 5.6 and the 4.0 earthquake on the 6th of Nov to create radii to locate the other points.

It looks like either a cavity collapsing or forming.

Some sources put 181 injection wells in that county.

It is also possible that the geology may be unique. The circular pattern suggests an impact crater. The two 4.7's and the 5.6 are at the central foci. An impact crater this big will tend to have a central rebound structure. The strong quakes seem to lie along the eastern edge of a potential rebound structure.

So instead of continuous geological strata, you got this bundt cake shaped structure with weak pulverized rock surrounding it. The rock infill around central uplift is easier to force up than along the edges of the crater. This structure is weakly integrated with the surrounding rock so it is particularly susceptible to fracking (hydraulic) separation.

Impact craters are often good places to look for oil and gas. Just don't get stupid and frack them.

I will need to find well logs and geologist's notes to verify if this is an impact structure.

I attended the meeting in Prague Oklahoma yesterday. Can you say cover up. Moratorium on new earthquake insurance in the state. They didn't voluntarily mention fracking once. Some people's houses were destroyed. Nothing to see here, just keep moving along.
 
Big Oklahoma Earthquakes, Edge of Impact Crater?

I was wrong about the size of the potential impact crater.

I found some rocks that look interesting but I can't be sure if they are impact melt or just weird rocks. I did find an interesting structure on some satellite photos at the BLM website.


The potential Crater is about 13.5 miles across, centered at approximately 35.557N, -96.871W. Nearly the entire town of Meeker is above it. I would guess that it is well over a 100 million years old. I am getting conflicting data about it's age, so I have to work that out.

Easily (sort of) Visible on BLM site, very difficult on Google to get the scope of the crater.

Center the area of Lincoln County between Highway 44 and 40. You usually need to decrease the zoom to see it better. If you zoom in too close you won't see anything. It has several small lakes outlining it's upper side. The bottom side is less distinctive and appears to be partially buried. The terrain is higher on the south side,so this crater may have been completely buried up until the last million years or so.

Meeker is in the southwest quadrant of the crater.

Google has pictures taken at different times of the year, with different color foliage, so you can't see it very well.

Using Google, I think I have found what appears to be a fairly wide ring of impact melt. It could also be an artifact of the surface geology. It looks like squiggly rock. At impact temperatures and pressures, solid rock can act like toothpaste.

Some sources put 181 injection wells in Lincoln County.

So instead of continuous geological strata you got this Bundt cake or bowl shaped structure with weak pulverized rock surrounding it. The rock infill and impact melt around the edges of the crater is much easier to force up then a normal rock strata. This structure is weakly integrated with the surrounding rock so it is particularly susceptible to fracking (hydraulic) separation.

A problem that has the potential to be worse than the fracking, is the waste disposal wells. These are usually dry, or used up production wells, used to dispose of waste and salt water. The rock around the impact site is highly fractured, though the cracks may have sealed up over time. You still don't know where the cracks might lead.

I would strongly recommend that a seismic survey is done to find out what the geology actually is down there. Those are the big thumper trucks that use sound waves to see what is underground. There may already be seismic surveys of the area, but they may be proprietary. It might be possible to continue some of these extraction techniques, but only after we get a lot better understanding of what is down there.

If you repeat this information, blame it on an anonymous underground group of geologists. I am an amateur geologist.
 
However I'm now wondering about a supposition I've heard that fracking in the UKmay have triggered earthquakes there. My understanding there was an investigation and the report said that it is "highly probably" that was the cause. I'd love to hear your analysis of this Brian.

The final report that deals with the seismic events at the Bowland Shale is available online here.

From the summary:

In this report, the probable mechanism of the events is described based on a careful technical analysis of all available data. It will be shown that many factors coincided to induce these seismic events, which are unusual for stimulation treatments. Since the chance for any single factor to occur is small, the combined probability of a repeat occurrence of a fracture induced seismic event with similar magnitude is quite low.

It goes on to examine all the risk factors in some detail and how they can be mitigated. In short, with careful monitoring, it shouldn't be much of a problem.
 
.....the big thumper trucks that use sound waves to see what is underground. There may already be seismic surveys of the area, but they may be proprietary. ....I am an amateur geologist.
You mean those thumper trucks that are made over in Ponca City where there are dozens of them line up in row?

Oh those.
 
A lot of the data outside the area of the Crater indicates that the exposed surface at the time was equivalent to the 3500 depth information that we have now.

The center depth appears to be at 10 miles, this from a single earthquake data point. With a diameter of approximately 13.5 miles this does not seem unreasonable.

If you want to get the well logs (form 1002A) and read them yourself you need to go to
http://www.occeweb.com/
on the gold menu bar click on divisions.
click on Oil And Gas
Click on Databases

http://www.occeweb.com/Orawebapps/OCCOraWebAppsone.html

READ the instructions (they kind of make sense) to load the special software. I use Internet Explorer rarely, but I use it for this site.

Once you get the software loaded, it took me a few tries.

Click on Archived Oil and Gas Database

If you were lucky, it will take about a minute for it to come up on the screen, after 3 minutes see if you actually loaded the software correctly.

Or you get an Error saying there is no Listener.

Most of the older oil wells don't use Latitude and Longitude, If you have the API number of the well it may give you the Lat and Long.

They use the Township, a supposedly 6X6 mile square containing 36 individual 1 mile squares called sections. These use a zig zagging numbering system which I believe starts at the top Right as 1 to 6 on the top Left DOWN 1 to 7 .

The section is the first number in the description. When you enter numbers in the data base each field has two digits. the number 2 is 02.

The Township is described by 2 Numbers The first is called the township Like 12N or 13N and the range like 04E or 05E

The locations that are those most interest are the ones just inside the crater or the ones a little distance outside the crater.

To find that information try this site http://www.geocommunicator.gov/GeoComm/lsis_home/townshipdecoder/index.htm

Click on GeoCommunicator PLSS map half way down the page.

UNCHECK Data Download Availability

Zoom in just to the right of Oklahoma City.

The Township Grid will appear as you zoom in closer.

Lincoln County is slightly to East-Northeast of Oklahoma City. You are interested in the part of Lincoln County South of I-44 and North of I-40.

As you move in, you can spot the upper half of the crater when you switch it Topo mode on the bottom.
UNCHECK PLSS or it will be difficult to see with the grid in the way.

You will see a dashed line running between I-44 and I-40. The dashed line crosses what appears to be a lake, that lake is part of an arc going slightly north to the left, and slightly south to the right. This is not an Artifact, it shows up in the well logs (with some lateral displacement).

CHECK PLSS so the township grid will come back.

The Crater Center is approximately at 35.557N, -96.871W Which is about 3413N04E 3.5D 3.0A

Section 34 Twn 13N Range 04E. I haven't figured out their fine verbal description. On the form 1002A there is a grid of cells 8X8. I count a mark on a line as a whole number and a mark in the middle of a cell as a half. The top left corner is 00Down 00ACROSS. The center translates to 3.5D 3.0A. Sorry I didn't have time to figure out their system.

The ones that show the inside of the crater also show the debris (Usually Identified as Shale) that fell back into the crater. This shale is usually below 3500 feet. If the unusually thick shale layer is resting at 3500 then you are outside of the crater. The thickness of the shale debris (from 3500 to the present surface) is an indicator of your distance from the crater cavity. Generally the thicker the layer, the closer you are to the crater.

Good places to look
West side 3413N03E
East Side 3413N05E
I am still working on the North And South Side

Well logs outside the crater will sometimes mention shale boulders at about 3500-4000 ft depth. This is my best guess for the surface that received the impact. Just outside of the impact crater, the exposed surface would have been buried in debris blown out from the crater.
 
The Crater was buried by Permian? and maybe some Cretaceous sediments. Some of those have eroded away revealing the upper side of the structure?

More likely, what is visible on the surface is not the actual structure. We are seeing the long term effects of faulting. As the sedimentary rock layers formed above the structure, they would develop faults as the structure settled. These faults would tend to erode more quickly then adjacent areas, We are probably just seeing the surface shadow of the real crater, which is still 3500 feet below.

Well after a bunch of wild swings in data and opinion, it is an impact structure, but it is useless to me since I can't get to it.

The surface at -3500 ft is my best guess for the surface that received the impact. The exposed surface just outside the crater would have been buried in debris blown out from the crater.
This one ID 1419434 NO API 1613N05E 24902? 1926 has Shale and Boulders from 3238- 3581.

This well ID 14030557 NO API 1613N05E appears to be inside the the visible upper radius but the debris shale layer appears to be resting on base rock 2545-3590.

Another API 0813772 1613N05E Shale 2753-3500.

One on the inside of the crater 3413N03E Shale 3555-4373 R A Roberts 1952.

Well I guess I am not going to Meeker to look for some impact melt.

Well that was kind of fun while it lasted.
 
Oklahoma, the Chew Toy of the Asteroid Belt

Meet the potential Choctaw Crater, the Meeker Craters really Big Brother.

There were a series of smaller tremors North of Choctaw which then shifted East to the Meeker Crater.

I actually spotted it on a map called GM-36, a Map of Oklahoma Oil and Gas Fields by Dan T. Boyd 2002.

I noticed a distinct circular segregation South and East of OKC. It is indistinct on topographic maps unless you know where to look.

The center is at approximately 35.060 ,-97.315

Radius approximately 33.45 miles. Diameter 66 miles. I am not sure if that is the biggest impact crater in the continental US or not. I believe it is bigger than the Chesapeake Crater in Massachusetts.

Age unknown: possibly the same as the Meeker Crater. It really trashed out the strata. Clean distinct Limestone lines get spread all over. I guess a lot of the debris went nearly straight up, or it washed back into the crater in a chaotic simulation of the original strata. Don't know if there was water above it. As a pure guess, I would say there was some amount of water present, to wash the debris back in.

Some of the carbonized material, could have been the end of a really bad day for something.

Some of the well logs seem to show the Crater edge , though it is more difficult to define as clearly as the Meeker Crater. See logs at 404N06W, it appears that between 6000 and 9000 feet, it is just a mess.

In the East I run into granite, in the West the depth of what is supposed to be concurrent strata makes it conceptually difficult to determine the time period.
 
In fact, small earthquakes are sort of a good thing because they release energy that was building up and would eventually cause a large destructive earthquake.

Do fracking operations go deep enough, on a large enough scale, to have any relevance at all to the build up and release of plate-tectonic energies?

Depending on the materials that are at the interfaces between the plates. Because of recent fracturing it would be difficult to pressurize with fluid. The addition of fluid could cause the rock to slip past each other with small local tremors to quietly build up stress in another part of the fault.

In the case of impact structures there is another problem. There is a transient crater depth and a permanent crater depth.

use this calculator http://impact.ese.ic.ac.uk/ImpactEffects/

The transient crater for an asteroid impact (I am finding iron and not just pyrite being mentioned in the well logs) is something like 13 miles for the Choctaw Crater. That doesn't include the fractures, though deep hot rock tends to be plastic. This can provide a path for fluids to soften or chemically change the rock over long periods of time.

One rather science fiction type possibility is the introduction of microbes into the oil wells to increase production. Something could just be stretching out down there.
 
Craters on Topographic Map

The asteroid impact crater causing most of the problems is about 13.5 miles across centered at approximately 35.557N, -96.871W. The smaller one I have (tentatively) named the Meeker Crater. The larger is the Choctaw (tentatively) Crater which is approximately 66.0 miles across located at 35.060N, -97.315W. I am guessing that they are between 250 and 300 million years old.

Sen Inhofe Slams Report that the Planet Krypton was Destroyed by Fracking

Statements from unnamed sources have verified that there is a concerted efforts by the Republicans to discredit an EPA report acknowledging that the planet Krypton was probably destroyed by Fracking.

Senators Coburn and Inhofe of Oklahoma award Superman a special congressional medal of freedom, made from parts from his former home planet.

Superman was unavailable for comment, and hasn't been seen since.
 
Texaco Buys Government Agencys Before Koch's Had a Clue

The United States Geological Survey is a corporate arm of Texaco.

Found two more possible craters to add to the two probables that I have found. One is actually overlapping the other. Bartlesville Oklahoma is near the center of the Northern one. The two new crater candidates overlap just north of Tulsa. Why doesn't Google work on finding large structures?

For Meeker and the Choctaw Craters I had a hard time finding wells dug down to the basement (usually granite).

These new candidates were drilled to the basement, 1952,1957, 1958.
Sections 16, 21, and 28 a straight line by the Texas Company. Township and Range 24N07E

So I was not the first to find these impact craters. Darn!

Texaco has controlled several state and federal agencies to make sure no one would be allowed to research these areas very closely. Their corporate Zombies would get to go to the top of the heap.

Too bad those damn earthquakes, gave the whole conspiracy away.

Wow, someone must have some balls in the EPA to give these guys the finger on fracking. Didn't the EPA get the memo that W sent out, you are all supposed to be working for industry just like the NIH.

I guess losing all that cover, that the Department of Justice was giving you, let you go soft and stupid. Just like the NIH.

Texaco another Texas success story built on secrets and using the government to screw their competitors.

Letting Texas in the Union has always been a bad idea. George W. Bush clinched it for me.
 
The Impact Craters that Texaco Hid for 50+ years and the current arguments for fracking. Senator Inhofe is so corrupt that he poisons the lakes he swims in.

Meeker Crater Approx. 13.5 miles in diameter. 35.557N, -96.871W
Choctaw Crater Approx 66.0+ miles in diameter 36.060N, -97.315W
Jeanne d'Arc Crater Approx. 101 miles in diameter 35.250N,-100.800 It is mostly in the Texas Panhandle and I know how much the Texans love France.

The rule change Oklahoma Corporate Commission 3-205 Who got this approved? Without the smeared lime and sand and the other anomalies listed on a geologist log, you could hide these craters nearly forever. The companies who knew about them could quietly and cheaply buy up the leases over decades. Bribe and manipulate the state Geological societies to keep geologists from snooping around. Meanwhile they could have the old data slowly disappear out of the public domain.

Jeanne d'Arc Crater also shows up as an empty semi circular space on the western part of map GM-36.

Also on GM-36 can be seen the affects that Choctaw Impact Crater had on oil and gas production, by the change from solid colors to freckles in the center of the state.

On the Northern Part of GM-36 Can be seen 2 more potential impact craters. One appears to be around Bartlesville, Oklahoma. Another, smaller one appears to overlap the southwest portion of the Bartlesville crater.

These are the holes into the Bartlesville Crater that got Texaco the prize. I would also bet they were able to drill wells that were never documented. Or Any documentation that was stripped of meaning , like getting Oklahoma Corporation Commission Rule OCC Rule 3-205 passed to hide the truth.

I would consider Meeker, Choctaw, and Jeanne d'Arc Craters to be 90% probable.

Who got there first, and who got their leases the cheapest?

Was it the little guy, or Texaco and the BP's?

Anybody for a quick trial, and a slow hanging?

The rich get richer, and the poor get a greater surplus of lies.

What is the lifespan of man made concrete in a subsurface environment?

What is the distance between high pressure salt strata and fresh water aquifers?

How much time does that give us?

At least some of the oil companies knew about the asteroid impact structures and the affects that these structures had on finding oil. Some of the structures I have listed have significant outlines on topographic maps. Underground using the oil well logs, I have found raised crater rims, ejecta blankets, (some over a thousand feet high). The chances that at least some of the oil companies did not know about these impact structures is incredulously remote.

Texaco appears to be one of the first to know. I can see why that Dinosaur killing crater in the Yucatan had such a battle for recognition (once you prove one crater it is easier to prove the next). A simple way to determine which companies knew, is to analyze their history of lease purchases. Did they show remarkable foresight in purchasing leases and then waiting for the technology and the demand to arrive? The wells are much deeper and they are mostly natural gas.

Once I had found the first Impact Crater at Meeker (by just following all those earthquakes), I wondered why the big companies didn't just fess up to the fracking causing the damage, and protect their reputations.

It seems they had a much bigger secret (problem) that they were hiding. I soon found another anomaly while looking at the ejecta blanket of Meeker Crater. I found Choctaw Crater using some of the earthquakes that Meeker didn't cause, combined with that strange area I saw on Map GM-36. I saw the blank semi-circular spot in western Oklahoma, but couldn't believe it was an impact crater until I got some better topographic views, and that map on Granite Plays in Texas and Oklahoma. A circular surface feature that also shows up thousands of feet underground. Duh, it's an impact crater!

I am an amateur so do not have any credentials. You will need to find someone who does.
I love the line from (Flight of the Phoenix) "I design model airplanes."
If you have any questions, or you would like some hard data, such as well logs (PDF), please contact me.
