GoodNews/BadNews on North TX Induced FrackQuake by Injection Risks

A study will be released relating to the Barnett Shale induced seismicity and how north Texans should prepare for a possible 6.5 earthquake. So I emailed one of the scientists of the study, Peter Hennings, who is the Principal Investigator for The Center for Integrated Seismicity Research at The University of Texas Bureau of Economic Geology and questioned if the large fault line near the Viridian (new Arlington upscale home development across from the dump and south of highly explosive petroleum storage tanks) was included in the study and he responded, “Yes, there is a large fault in the subsurface of that area and it is included in our study”. He went on to explain (which should have been good news) that the big faults aren’t the problem. So I have asked for clarification as I have rephrased his statement to more easily read…. (I have also boldfaced for emphasis)…”

“In fact, in almost all of the areas where induced seismicity has occurred in the last decade in the southern midcontinent of the US, these induced seismic events have NOT occurred on ‘known’ larger fault lines, but rather has been occurring on previously unrecognized faults”

His response was, What you wrote is accurate in my opinion. Regards – Peter.”

So then in my opinion the broad bad news is in the unknown smaller (therefore more numerous?) fault lines which to me could be an induced-insitu-nightmare-in-wait-of a-whack-a-mole situation with ALL the injection wells in Texas.

To add to the bad news, Texas Sharon of, had some email input to Mr Hennings’ (now in doubt) good news email…..

Mr Hennings wrote:

“…but given that the rate of injection is quickly decreasing in the DFW area means we should be ultimately headed for less risk overall. Thanks – Peter”

TX Sharon responded….

“Hello, I was copied on this email so I would like to find out how we know that the injection is decreasing? People who live by the injection well at the airport report that activity has picked up quite a bit with many trucks coming and going.

Mr Hennings responded to TX Sharon….
“In our research we typically do not track individual wells  – we mainly work regional trends.  Like everybody, we get our data from the TX-RRC and, by their reporting and rules and operational lag times, means that injection data is always about 14 months out of date.  As a region I can say with confidence that injection rates have declined year-on-year for the past 5 years but I don’t know anything about the most recent 14 months.
Regards – Peter”
In closing and opening up the can of worms for what I feel can be the worst possible news, this study may not even speak to the induced seismic risk with sub-earth flooding, (aka hydraulic fracturing) which can number in the tens of thousands of gas & oil wells just in Texas.
The focus on induced seismicity has been on injection wells which violate Mother Nature over a longer duration which equates to cumulative, higher wastewater quantities.
Enter Dale Henry:
FYI a retired, decades experienced, well plugger named Dale Henry begs to differ on what can induce seismicity. Being a former Petroleum Engineer (who had interesting stories of assisting Kings in the Middle East) and a repeat candidate for a seat regulating the oil & gas industry in Texas, Mr. Henry has the respected opinions that:
  • fracking is of more intense pressures; 
  • that even short violations of Mother Nature can set into motion seismic responses years later.

Here is his video testimony…

Here are my notes I took ….

Contrast the insane aggregate number of gas wells to the number of injection wells, and all that energy has to burp somewhere, sometimes.

Henry provided stats:
barrels per minute of injection wells = 2-3 bbl verses
barrels per minute during fracking = about 200 bbls
PSI for injection wells = 1,000-3,000 PSI verses
PSI during fracking = 10,000-20,000 PSI.
Time frame of energy storage before seismicity = 18-30 months or less.

About Kim Triolo Feil

Since TX Statute 253.005 forbids drilling in heavily settled municipalities, I unsuccessfully ran for City Council Seat to try to enforce this. Since Urban Drilling, our drinking water has almost tripled for TTHM's. Before moving to Arlington in 1990, I lived in Norco’s “cancer alley”, a refinery town. It was only after Urban Drilling in Arlington did I start having health effects. After our drill site was established closest to my home, the chronic nosebleeds started. I know there are more canaries here in Arlington having reactions to our industrialized airshed (we have 55-60 padsites of gas wells). Come forward and report to me those having health issues especially if you live to the north/northwest of a drill site so I can map your health effects on this blog.
