Officials in Red River Parish are concerned about the frequency and severity of recent earthquakes in the area. While some officials believe the earthquakes may be related to fracking and injection sites, state geologists say more data is needed to make a determination.
This week a discussion with parish officials and the Louisiana Department of Natural Resources began with questions centered on the frequency of the tremors in our area. For state geologists the frequency of the earthquakes and the severity were not of immediate concern. The frequency usually reaches 30-40 before initiating a study. All but one event has been below 3.0 on the Richter Scale, and the geologist explained this was a minor event. “Your area may have many more seismic events, or you may see it end with this last one. We cannot determine what will happen.”
Residents of Red River Parish expressed concern about the frequency and severity of earthquakes, with many asking if the situation will worsen and when it will stop.
Officials at LDNR stated that no study of earthquakes in the area exists to compare the current situation. They explained that more data is needed to make a determination and that more earthquakes would help gather better data. However, this does not provide comfort to those who have experienced their homes shaking.
Next, the questions began to move to the possibility of problems with oil and gas drilling in the area. Officials from LDNR explained that reports indicate that fracking in the area of the earthquakes had ceased before the first earthquake occurred. They next discussed that they are studying the information for injection wells in the area. A study of prior reports, questioning operators of the wells, and requesting site inspections may help to determine if any of the earthquakes could be attributed in any way to oil and gas production in this area. At least a week would be needed to begin to analyze the given information.
Injection wells are used to inject fluids associated with oil and natural gas production. Class II fluids are primarily brines (salt water) that are brought to the surface while producing oil and gas. She said that with drilling, there is always a byproduct, and this waste must be disposed of. This disposal is now done by injecting it back into the earth. Annual reports of the pressure and depth of injection wells are due to LDNR each April. Over 4000 injection wells are in the State of Louisiana. Red River has at least seven.
Next week, a presentation on injection wells and more information from the collected data will be presented to area officials. In the meantime, emergency responders in the parish have begun preparing for the possibility of more frequent and increased severity of earthquakes.
