New Injection Well induced quake 5.6 in Oklahoma

[Bob]

A magnitude-5.6 earthquake – matching the strongest temblor to ever hit the state – struck north central Oklahoma on Saturday morning and could be felt over a seven-state area, the U.S. Geological Survey reported.

The jolt rattled a wide area of the Great Plains, including Missouri, Kansas, Texas, Arkansas, Nebraska and Iowa.

It was centered about 9 miles northwest of Pawnee, Okla., prompting local officials to dispatch officers to check key facilities, such as the local water plant.

Wastewater Injection Wells (injection wells, not new well 'fracking' is the cause of shallow earthquakes) - Note the areas listed with the quakes map above -

Looking at the injection well map above and the fault map below, the Pawnee area slippage was triggered due to the injection well cluster right near the fault.

Study showing induced earthquakes -


http://www.magma.geos.vt.edu/vtso/induced_quakes/induced_figs_for_vtso/denver_arsenal.png

It has been known about since the 1960's but the State has allowed oil companies to inject wastewater, under intense pressure deep into porous formations, which can absorb the waste. After a while, the formation starts to slip with the additional fracturing. Wastewater has been found up to 20 miles from the injection sites.


http://www.magma.geos.vt.edu/vtso/induced_quakes/USGS_induced_quakes.png


Induced seismicity -- earthquakes that are induced or triggered by human activity -- is on the rise all across America.

The biggest seismic news is coming out of Oklahoma, but Ohio, Arkansas, Texas, Colorado, New Mexico and West Virginia have also experienced an increase in significantly sized earthquakes due to human activity.

There is a clear correlation between high-volume fluid injection and recent increases in earthquake activity in Oklahoma and other states.

The process of fluid injection activates old basement faults that already exist. The introduction of such high volumes of fluid increases pressure in the pores of the rock deep underground, which in turn, can weaken faults and trigger earthquakes.

It's important to note that the fluids do not create new faults: they simply activate old faults that already exist.

Wastewater disposal wells associated with hydrofracking are the leading cause of induced earthquakes today, but water-flooding wells associated with enhanced oil recovery may also be part of the problem.

The issue onawah with dutchy as I see it, and I have done a lot of in-field research in the oil fields, is the constant mis-information push saying it is FRACKING - fracking has nothing to do with lubricating the Arbuckle injection zone which is very deep. As long as people are pushed into misinformation due to what seems to be lack of technical skill to read scores of scientific research reports on the dangers of DEEP INJECTION wells (not one time fracking), one is going to continue to jump into the hype of "fracking".

I have some good threads up on Injection wells, and their dangers.

Looking at the Injection Well Map I posted above (OP #1) one can see if there is an INJECTION WELL in the area, one can pretty much ENSURE that there is going to be an earthquake. It doesn't need a crystal ball to "figure out the obvious" and claim "they predicted it".

Reputable university research has pointed out the damage from Injection wells.

http://www.magma.geos.vt.edu/vtso/induced_quakes/induced_figs_for_vtso/denver_arsenal.png

I posted above also direct data from the 1960's the correlation between injection wells and earthquakes.

No rocket science needed.. Just look where INJECTION wells are, not fracked new oil/gas wells.

My thoughts on this disinformation/misinformation campaign -

When one is using FRACKING (Hydro-Fracking using high pressure water to open up a new tight formation (usually in a shale zone) ) there is water left in the formation, and there is water which comes back up, and the water that comes back up is CONTAMINATED with the stuff from "down there" (radioactives, toxic metals) and has to be disposed of.

That is the issue with fracking the DISPOSAL of the water.. So industry goes and finds old wells no longer worth producing which went deep, and they use those wells as toilets to flush the waste down deep way deep, under pressure, right at the spot where small quakes can be amplified and transmitted many miles.

BUT INJECTION wells have been used since the 1950's to capture the ASSOCIATED WATER which comes up from an oil and gas well. Deep in the earth where the oil and gas is found, there is associated water, at times up to 3X contaminated water comes out than oil that comes out.. BILLIONS of gallons of associated water comes out, continually with production. IN the old days, that was simply poured onto the land, then EPA came in said NO WAY !! so Industry then needed to figure out a cheap way to transport and dispose of it.

I would NOT put it past industry to try to focus attention on FRACKING to divert it off their INJECTION WELLS, sorta a sleight of hand to get some shills to start spinning that it is fracking doing the dastardly deeds.. Given the misinformation and the fervor created by those who never looked up the damage from injection well quake induction (remember its been know such happens since the 1960's), those people bought into the lies about fracking damage..

Why would industry do that? A LOT of the majors have already put in producing fields and they have made BILLIONS on such. A LOT of the new small companies want to get in the field and produce, to cut into the profits of the majors. The majors and they are US and FOREIGN do NOT want competition in their established fields.

The deposits all over Texas and North Dakota contain MUCH MORE USABLE OIL, a very very good clean oil devoid of high sulfur content (sulfur is a nasty toxin responsible for acid rain etc.) and the Mid East Oil for instance Saudi Arabia (the second major producer) does NOT WANT the US to be ENERGY INDEPENDENT ! Fracking done down at -10,000 feet below the surface does not reach the basement rock, (which is in that area, about -22-24,000 feet below the surface), and it does not induce quakes while the thin shale zone (called the Bakken) is opened up to allow the very good grade pure oil (no sulfur) to be extracted.

So look there for the source of the "fracking" disinformation campaign, and the bandwagons the good hearted people are falling for.. (due to not doing the full research, but relying on 'sensationalism')..

WHEN you see WHO is selling energy, RUSSIA, Saudi Arabia, and who may very well want countries who buy natural gas, and oil from them to NOT DO IT ON THEIR OWN, you WILL SEE fracking bans - they are doing that so that the existing MAJORS in those countries can maintain an energy and economic stranglehold. It is SIMPLE to see this if one pays attention to who is being hamstrung by the disinformation campaigns stopping energy production and ENERGY economic independence from those awfully nasty financial manipulators.. Russia and Saudi do not want their buyers to stop buying at inflated prices..

But aren't deep injection wells the side effect of fracking? Just one step removed, but they are certainly related. We wouldn't have the latter without the former.

[Bob]

But aren't deep injection wells the side effect of fracking? Just one step removed, but they are certainly related. We wouldn't have the latter without the former.

Absolutely NOT.

Injections wells primarily are used for taking ASSOCIATED WATER that is produced from over 90% of all the oil and gas wells.

http://www.reuters.com/article/us-usa-shale-water-kemp-idUSKCN0J223P20141118


The biggest product of the U.S. petroleum industry is not oil, gas or condensate but water -- billions and billions of gallons containing dissolved salts, grease and even naturally occurring radioactive materials.

In 2007, when the shale revolution was still in its infant stages, the U.S. oil and gas industry was already producing more than 20 billion barrels of waste water per year, according to researchers at the Argonne National Laboratory (“Produced water volumes and management practices in the United States”, 2009).

The industry’s daily output was 5 million barrels of oil, 67 billion cubic feet of natural gas, and 55 million barrels of water, according to federal government statistics.

Argonne estimated that more than 7.5 barrels of water were produced for every barrel of crude, and 260 barrels of water for every million cubic feet of natural gas, based on state and federal records for onshore oil and gas production.

Fracking water accounts for maybe at best 0.5%.

Existing production going on for 25-50 years produces water. The amount of NEW WELLS fracked is minuscule..

What is being hidden from sight, and seriously it is horrendous, the injection well problem. Which has been known about long before hydraulic fracturing was invented to deal with the tight shales in North Dakota, the deep shales of Texas, and the Marcellus formation in West Virginia and Pennsylvania.

It has been likened to taking the Mississippi River's total output and pumping such down to the basement where the faults can pick up and amplify that extra pressure.

(see some addition to my post above)...

FRACKING happens ONCE - period. MAYBE after 3-5 years of operation a well may be acid fracked (hydrochloric acid is pumped into the fissures to re-open them similar to how a cesspool is cleaned with hydrochloric acid to open the pores), or a secondary re-frack may be attempted.

A hydrocarbon well producing either oil or gas gets natural deeply trapped seawater (2500 feet from the average shallowest, to 18,000 feet below the earth's surface), from the ancient seas which were present 65-180 millions of years ago, which with the organic sediments eventually layered up by rock/carbonates/shales formed under pressure, oil, and gases.

See my posts about the dangers of injection wells, to understand how contamination can happen. It can happen from oil industry being STUPID about other OLD wells in the field which may have cracked casings.. BUT it is not the FRACKING doing it, is the INJECTION WELL waste pressure coming up through old casings on OLD wells not properly plugged.

This thread points out the INJECTION WELL CAUSE of the 5.6 on the Pawnee fault zone (see OP #1) on that fault map.

Right on the fault zone, industry placed an injection well cluster.. STUPID beyond belief.. Nobody in their right mind pumps high pressure water into a known fault zone. Pawnee where the injection wells are located is right on the major faults.

It doesn't take rocket science to look up data and connect dots. The fracking disinformation is the issue when injection wells are the cause.. That's the point.

[onawah]

Thanks Bob. That's reasonable insofar as the ratio amount of water/contaminants that are being injected from oil and gas industries compared to fracking alone, but I would think that fracking also contributes to quakes, though I don't know how that could be measured.
The other serious problem with injection wells, of course, is contamination of the water table. Erin Brockovich has been doing a lot of activist work on that score, and posts something on Facebook every day about it.
Simon Parkes said something very accurate, I think, when he said that the US is going to be dealing with the severe and harmful effects from that for a long time to come.

What about the rights of Mother Earth? Casey Camp-Horinek testifies on Fracking
Indigenous Rising
PagaveyfMDA

Published on Dec 5, 2015
There are now 13,000 fracking wells in Casey Camp-Horinek's community. Since Fracking hit, she's seen her community go from having 5 earth quakes in the year of 2008 to over 5,000 in this last year alone. All of these earthquakes happening right now are directly related to the injection process involved in Fracking.

One can go over the new wells being created per year. Statistically look at the amount of existing wells which have associated water, and the injection wells which DAILY pump billions of gallons of water into the ground onto the actual deep fault zones over bedrock.

Nobody is drilling down to bedrock and making any money. The shale layers where oil is trapped is located much higher above the basement rock. Basement rock is like granite.. Shales and sands and carbonates are old sedimentary layers made up from organic materials and limestones where oil and gas can become trapped.

There is no such thing as FRACKING WELLS!

That statement made in the above post, is a clear misnomer to anyone skilled in the field.

A well is HYDRO-FRACKED ONCE if it is going into a "tight formation" or ACID fracked when a simple carbonate limestone has to be opened up. The well is not ever continually FRACKED under pressure.. That would be wasteful, expensive (2-4 million dollars per well during each fracking operation). Microseismic activity (less than 1-2 on the Richter scale) happens during simple fracturing which opens up small seams in the formation that has hydrocarbon production within. It is BRIEF and one time, a rattle similar to a large truck moving in a parking garage.

Hydro Fracking involves pumping IN a few million gallons of water into a very small area, a production zone (shale or limestone) typically 10 foot thick by up to a mile in length. At least 3/4 of the amount of water put IN by the fracturing operation is REMOVED.

Such "fracking" operations are usually for a horizontal "shale-oil well"; That newly FRACKED oil well or gas well, can cause a brief expansion of possibly 1-2 inches at best while pressurized, adn that pressure is quickly removed. AND FRACKING is done ONCE. PERIOD..

IT is never ever a "fracking well" which misnomers "continually fracking".. I firmly believe that is one of the dis-service mis-information points being continually spread by non-informed but good hearted people. Nobody in the industry wants to waste money. Greed is rampant.

The amount of water spread in such a "fracked" well is possibly at best 200 - 300 feet surrounding the well bore (the hole drilled). What more often happens during the spreading is micro-seismic activity happens from a fracking operation in a normal well. Look at my Jello analogy below to understand this better..

In Fracking, local small fractures about pencil size thick are opened up, allowing more surface areas for drainage into the well bore (the collection tube) of the water/gas/oil. The fractures are held open by small particles which can be sand or other proppants, small objects which are inert to keep the fractures expanded. The waste frack water, lets say 3/4 of that amount is pumped back up and that's it, its over. No more pressuring, no more micro-seismic vibration (wiggling under 1 on the Richter scale). We feel more damage from large trucks on bridges, elevated parking lots, freight trains running locally "pressurizing" compressing and vibrating the earth.

In CONTRAST

High pressure pumping into an injection disposal well is VERY DIFFERENT and can increase the uplift up to 10-50 feet or more. Pumping downwards under intense pressure into a disposal "injection well" goes on day after day after day after day.. Relatively non-stop, because existing producing wells (20 miles away, or further) are making associated water (taken OUT) that has to disposed of. Nobody talks about where that associated water that comes UP from the natural underground ancient salt water seas will go.. And there is the problem..

Industry finds a "toilet" (the disposal injection well) and starts to over-pressure, more and more associated "production water" is forced into it until something breaks "quakes happen".

AND that pressurized "toilet bowl" disposal injection well water MIGRATES, not 200-300 feet from the well but up to 100,000 feet or more away from the well. AND any numbers of faults can exist that far away from the injection well, never-before mapped.. only to show up with those faults are lubricated by the incessant, non-stop injection high pressure pumping..

People 20 miles away can experience EARTHQUAKES in other-words, quakes are coming not from any locally put in new wells (once maybe fracked), but from the INJECTION WELLS taking that associated water, and putting it back in elsewhere under extreme pressure, and the people near the new wells will most certainly not have researched WHERE the damage REALLY is coming from.

THE QUAKES CONTINUE, not from the new wells with a one time frack if they had that, but from the CONTINUAL DAMAGE from injection wells somewhere within a 20 mile radius.. THAT is the ISSUE, hidden overlooked and distracted from people's sight and mind. Understand that.

Logically the massive expansion produced during injection wells is the damage source. Fracking creating a minuscule expansion and the fracking water removed for the most part (3/4 of it at least), is not damaging enough to cause massive earthquakes..

It's statistics and volumes involved.

That's where errors happen.. People hear FRACTURING and don't understand volumes, or distribution of where the water and pressure goes.

Fracking is more like sticking a pencil into a bowl of JELLO.. When putting the pencil in, one is going to see some damage where the pressure momentarily is. Taking out the pressure of the pencil and the cracks SEAL themselves very rapidly. The Fracked well becomes very STABLE.

NOW, Injection well trauma is like taking a Turkey Baster and filling it up with water, and stick that into the bowl of Jello and squeeze.. A WHOLE lot more damage is going to happen where the water exits...

AND now take out the baster and insert an ENEMA bottle filled with water, into the Jello and let 'er rip.. Let the whole bag empty in (be sure to SQUEEZE the bag hard too!), then add another one and another one, and another one and another one every hour, continually.. After a while the mess is horrendous.. THAT is injection well reality.

Fracking is hardly anything worth comparing as far as actual DAMAGE from the expansion operation..

When FRACKING goes bad, OR injection wells most OFTEN go bad is when there are additional WELLS in the area within the 200-300 foot proximity to the to be fracked well or the injection well, in which the concrete SEALS up through the drinking water table have not been properly re-sealed, before any fracking operation started, or injection well operation started.

What PEOPLE miss, and the INDUSTRY HIDES is they do not check INTEGRITY of the older wells..

A well has to be drilled through the SURFACE water table area (100-1100 feet), and proper concrete sealing has to happen, to maintain integrity between the rock, the sands, and the well bore.. After years concrete breaks down.. And of course Industry KNOWS THIS.. Which is part of the reason they abandon old wells, unless they want to pour new concrete and then drill through such thinking that maybe they missed something in the old well..

An old cracked casing for a well that goes down into the exact zone (production depth) in which an injection well resides (called TD or total depth) means that the injection well is going to push its waste LIQUIDS UPWARDS into the old well, and potentially through a cracked casing.

THIS IS POTENTIALLY DISASTROUS as far as contamination of water table.. IF a new well being fracked, has a connection to an OLD WELL which also has similarly cracked CASING concrete, that fracking water pressure WILL GO UP through the old well and INTO the water table potentially..

THOSE issues are HIDDEN by INDUSTRY.. It isn't the minute microseismic that happens when the 'pencil is stuck thru the jello' issue, but the OLD WELLS IF THERE ARE ANY, leaking if they are in the fracked or injected formation... AGAIN though, the INJECTION WELL, the subject of this thread, is the cause, not any fracking happening in the area..

OLD WELLS up to 100,000 feet from the INJECTION WELL could contaminate the water table if the concrete casing is leaking/cracked (due to age, or poor bonding during "completion" operations)..

HIDDEN FAULTS which are being LUBRICATED (allowing such to lift and slip/slide) some miles away from an injection well system many miles away really, can be affected.. When the old well's metal tubing was pulled, when the "plugging job" was haphazard, and many many wells were inadequately "plugged" over the years from 1906 onwards, the LIQUID PRESSURE from the injection well can migrate UPWARDS, through the old well casing and into the other zones, or faults present, and all HELL can break loose as it has..

THAT is the mechanical that is happening. One can see the statistics the differences in volume involved.

Take a pencil and push it up under a tray on a table, then remove the pencil, the stuff in the TRAY doesn't fall over, it may wiggle a little bit, show some small vibration, but the stuff on a tray is not toppled. That is another analogy to fracking uplift/expansion.

Now take a 10 foot diameter drain pipe, and put that under the tray.. Things are gonna go all over the place, one can't prevent the mass of the 10 foot diameter drain pipe, it's volume from damaging oh so much..

It's easy to visualize that way..

[Bob]

On your question about Mother earth.. Look at the output from the numerous volcanoes which is going up into the atmosphere, creating billions of tons of waste gases, contaminating the atmosphere that everyone and everything has to breath, the waters have to absorb the toxic gases. There is more damage induced environmentally by natural venting sources (methane seeps) naturally releasing "natural gas" from the earth, than any wells since 1859. Statistics once again.. Man simply cannot extract or pollute more than nature does, NATURALLY..

The PLUGGING and DRILLING ISSUE -


More than a million oil and natural gas wells were drilled in this country before anyone really knew how to plug them.

Once the oil or gas was gone, the wells were abandoned with little thought of future consequences.

Some have been open holes in the ground since the 1800s. Others are plugged with little more than dirt and logs.

For decades, old abandoned wells have leaked oil, natural gas and brine into soil and drinking water, and posed an explosion risk.

The danger is often hidden. Hundreds of thousands of abandoned wells were never properly mapped. Many of the companies that drilled them no longer exist.

Abandoned wells lurk beneath homes and buildings in Ohio; under the busy streets of Los Angeles and the sparse Oklahoma plains; and in parks, backyards, forests, cornfields and cemeteries from Appalachia to the Pacific Ocean.

Abandoned wells are the unwanted legacy of 150 years of drilling booms and busts. Now those old wells pose a new danger as the country rides another petroleum boom driven by hydraulic fracturing techniques that unlock vast new reserves.

The abandoned non properly plugged wells pose a risk when new pressurizing is happening for the reasons I mention above in my post.. LEAKAGE upwards..

I have never ever seen any existing oil company do a study which should be MANDATED by the various oil and gas commissions regulatory bodies per State. The study should LOCATE and test the integrity of ALL WELLS IN THE AREA, historically before commencing with:

Injection well creation
Fracking a new well


If the zones (the area in which the bottom of the well is opening up, or connecting to) tie into old wells, the old wells must be checked and or re-cemented for integrity. That should be a mandate for any newly to be pressurized "fracked well" or deep disposal (injection) well.

Here is some history of the big REAL ISSUE behind more of the "frack madness drama" (i.e. gas coming out of my water tap !! eeeee !!!!) how it happens:


At least 4 million wells have been drilled since 1859. Of those, a million are still producing oil and natural gas. New wells are drilled each day.

Beneath the topsoil, the earth's crust is a layer cake of alternating bands of rock, sand and clay. Some layers hold freshwater; others oil and natural gas.

Drilling a well through thousands of feet of geological layers creates a passageway between the layers. Drillers line the hole with steel pipe held in place by cement. The steel and cement linings keep oil or gas from escaping into other layers of earth, and groundwater from leaking into the wellbore. Oil and gas can then rise to the surface.

After the supply of oil or gas is depleted, companies plug the well with a column of cement inside the steel pipe to prevent future leaks or seepage.

Old abandoned wells often fall short of modern plugging standards, or lack any plugs at all.

The oldest wells have casings made of wood instead of steel. Other old wells had their steel casings pulled from the ground for scrap metal during World War II.

In 1879, New York was the first state to make drillers plug unproductive wells. Other states followed. But the early rules were designed to keep water from flooding oil deposits. Groundwater protection only became important decades later.

Oklahoma Corporate Commission gives in - says SHUT down those bloody injection wells !

Oklahoma, EPA shutting down 32 disposal wells
HOUSTON, Sept. 13
09/13/2016
By OGJ editors (Source)

Oklahoma state and US Environmental Protection Agency regulators said 32 disposal wells in northeastern Oklahoma must shut down following the discovery of a fault line believed to have caused a 5.3-magnitude earthquake on Sept. 3.

The newly discovered fault is near the town of Pawnee, farther east than most previous Oklahoma earthquake activity. The fault has yet to be named.

Jim Marlatt with the oil and gas division of the Oklahoma Corporation Commission said the latest action means wastewater being injected in the area will be reduced to 35,000 b/d from 75,000 b/d.

Apparently they looked at my fault map above in the OP post #1. It is well known that Pawnee County has faults.

Why just now did they realize that the injector wells up there were injecting within a fault?

The ISSUE IS a WORLD-WIDE ISSUE. This thread points out the technical facts which are being overlooked (probably deliberately) by those who want to dispose of 'cheaply' without considering the consequences of associated water disposal. It doesn't matter if the water came from a fracking operation or from oil/gas production.. The points illustrated in this thread are very clear, about migration of liquids into overpressurized zones, what happens, with not just faults directly within the zone being injected, but by cross migration upwards through old wells improperly plugged or currently deficiently plugged due to casing leakage, cement bonding issues, or decaying crumbling old cement..

Pay attention.
