Seismic discoveries trigger New Mexico to cancel dozens of oilfield wastewater injection wells

A recent increase in previously unrecorded earthquakes in New Mexico’s Permian Basin has prompted the state to halt plans for 75 wastewater injection wells, citing a connection between these activities and seismic events.

Key points:

- The Oil Conservation Division in New Mexico has cancelled 75 wastewater injection well projects due to the identification of thousands of small, induced earthquakes.

- Injecting wastewater into underground formations raises pressure, leading to seismic activity in nearby areas.

- Recent machine learning research has revealed many undetected earthquakes, informing state regulations aimed at preventing further seismic issues.

Why it matters:

Wastewater injection from oilfields can trigger earthquakes, threatening infrastructure and public safety. As oil production rises, so does the volume of toxic wastewater, heightening concerns about managing this waste without increasing the risk of seismic activity.
