BATON ROUGE- Some say two earthquakes in East Texas, in a week's time, has ties to oil and gas activity in Louisiana.
Scientists from the U.S. Geological Survey made the possible connection this morning after the latest quake sent tremors into the Shreveport area.
Experts say taking natural resources from the ground and even shoving materials into the ground to get those resources out, as is being done in the Haynesville Shale in North Louisiana, may be causing the mild quakes. Fracking, a way to find and recover oil and gas underground, is happening in other areas of the country as well and because the same kind of activity is ramping up across our area, in the Tuscaloosa Marine Shale, we could get shaken up too.
Dan Collins, with the Tuscaloosa Marine Shale Landowners group, said, "It is something to definitely watch, and to be concerned with. It's just in this part of the world, because we're so deep, with the formation, with the Tuscaloosa Marine Shale, I don't think we're going to have that problem. Although I will be the first to admit that it is early."
And some experts say the rumbling could open-up scientific secrets.
"Even though we've extracted oil and gas and water and all sorts of resources from the ground, and we use the ground all the time, we really don't know what's down there," said Geology and Geophysics Professor Juan Lorenzo, "And having this array and these small natural earthquakes occur allows us like a CAT-scan to see a little bit better what's down below."
The Tuscaloosa Marine Shale has about three dozen wells in action now. Half have been drilled and some are producing 800 to 1,000 barrels of oil a day.
