Oil Production Possibly Linked to Eagle Ford Shale Tremors

A study published in the Earth and Planetary Science Letter suggests that there is a link between oil production and a string of tremors in the Eagle Ford Shale.

About the Eagle Ford Shale Study

  • The study collected 2 years of data over a number of recent earthquakes in South Texas in the attempt to find a possible cause. This included gathering data on a 2011 magnitude 4.8 earthquake that was felt in San Antonio.
  • While researches originally thought the tremors would be linked to injection wells, as they were in a previous study of the Barnett Shale in North Texas which was conducted by the same group, they instead found that the tremors are likely tied to the extraction of liquids like oil and water.
  • Two other studies had also linked injection wells with increased seismic activity: a report by the U.S. Geological Survey and a study conducted by Ohio State regulators.
  • This is the first large scale study to link seismic activity with oil reservoir depletion.

Conclusions of the Eagle Ford Shale Study

  • As water and oil are removed from the ground, surrounding rocks and sand begin to settle triggering the tremors.
  • The study compared the cause of the earthquakes to occurrences in Long Beach, California in which oil production and ground water wells caused most of the area to sink by nearly 30 feet.
  • The researchers also recorded 22 quakes in Dimmit County. The area reported no tremors before a recent uprising in oil production and water extraction.
