East Texas 3.7M earthquake

At 10:15 today East Texas had a 3.7M earthquake 1 mile west of Timpson, Texas right in the middle of a drilling area.

UPDATE:  FYI, Louisiana sends all their drilling waste to Texas for disposal. It’s great for the economy!

Two disposal wells very close to the epicenter. More information about disposal wells in the area HERE.

TIMPSON, Texas (AP) Authorities say a 3.7 earthquake has shaken parts of East Texas.

The U.S. Geological Survey says the tremor struck Thursday morning in an area between Garrison and Timpson, about 24 miles northeast of Nacogdoches.

Gary Patterson of the U.S. Geological Survey in Memphis says survey geologists are baffled by the event. He says, “It’s not where we normally see earthquakes in Texas.”

Timpson City Secretary Tanya Windham says she initially thought a nearby train had derailed and it “shook the whole city hall” for about 15 to 20 seconds.

Nacogdoches County Sheriff Thomas Kerss says the shifting earth cracked concrete and brick support columns and window panes but did no significant damage.

There were no reported injuries.

    I wonder what an earthquake like that does to the casing in the wells. Even a crack could cause containment issues.

  2. Nate Spin says

    We’re about 2 miles south of Timpson, we felt it. Sounded like someone was shaking our house… What fun…
    We had another one about a year ago, but I can’t find anything on the net about it.

      Shelby County has in excess of 2000 wells drilled with, 1517 drilled between 01/01/2000 – 05/10/2012 according to a quick search of the Texas Railroad Commission Website, while not quite the enormous amount drilled here in the Barnett or West Texas, there are quite a few as you can see on the map posted. I would still have my water tested if it came from a well or an aquifer near those injection wells, no sarcasm, completely sincere.

  3. Ger says

    Incredible and East Texas isn’t even on a fault zone. No other explanation, has to be fracking. Studies have proven the links between fracking and earthquakes.

  4. Melanie says

    What is being disposed of in these disposal wells? How are the companies disposing of this waste? In what amounts? Is there active fracking going on in the area? How far from the epicenter?

    • says

      The wells are for disposal of flowback and produced water and liquid waste from drilling and fracking. They inject the fluids down into the formation. There is quite a bit of activity in the area. Those are just the first two injection wells I located with a quick look.

      According to the event page the epicenter is 31.901 N and 94.422 W. I updated the post with screen shots showing the location of the two injection wells I saw and you can see they are close. There may be more.

    I saw in a news report that there was a gas leak in that area at the same time as the earthquake. It was unrelated, of course.

  6. Andy Mechling says

    Please keep in mind that these so-called “disposal” wells often are used for Enhanced Oil Recovery (EOR) or “Pressure Support” for nearby production wells drilled into the same formation.

    EPA’s Underground Injection Control (UIC) program specifically allows for Oilfield wastes (Class II injection wells) to be injected into subterranean formations for either disposal or for EOR.

    Guess which one they choose?

    The truth seems to be that activities at these UIC wells are not really as easy to differentiate from fracturing, well completion, flowback, and workover activities as some would have us believe.

    In any case, I would enjoy entering into a discussion of this topic with someone who knows more about it than I do. I sure do have some questions.

    My editor sent me a note about this and asked me to follow up since I wrote an article a few weeks back. It never occurred to her or to me that this was anything else BUT a fracking quake once I looked at the map. Anybody want to do an interview? We’ll publish it. It is cRazY that this is going on. The evidence is overwhelming, so much so that it was hard to keep this article from being a small book. http://www.redorbit.com/news/science/1112514882/shaken-stirred-or-fracked/

  8. Thinking Engineer says

    There is a history of small earthquakes in this area, believe it or not. These earthquakes have been happening long before any oil and gas “fracking” took place. Remember this when environmentalists start blaming these earthquakes on fracking. In 1957 and 1964 there were two series of similar earthquakes in East Texas and along the TX/LA line. http://earthquake.usgs.gov/earthquakes/states/texas/histor​y.php

    • says

      Injection/disposal wells cause earthquakes. Pumping fluids near a fault is not a good idea. This has nothing to do with environmentalists.

  9. Oil worker says

    There is little…if ANY new well work going on in the Timpson area, which means there is no “fracing” going on. East Texas is a natural gas producing field and all the oil companies are going after oil these days due to the price of oil vs nat gas.

      • Katy says

        So two injection wells injecting water at less than 1.98 km cause earthquakes at 5.1 km. Interesting use of the logical fallacy: “correlation proves causation.” Smells alot like a case I read about in Parker county.

        • Brian says

          The weight of the disposed waste water alone could cause stress on the existing fault in that area. There is gravity all the way down to the center of the earth, you know.

        • says

          Katy, Katy, Katy… you know, of course, that those two injection wells are not the only ones in that area.

          The case in Parker County is not over yet.

  10. Anonymous says

    “The number and strength of earthquakes in central Arkansas have noticeably dropped since the shutdown of two injection wells in the area”
