Catching Oklahoma’s Tiny Tremors in the Act

by E. Frederick 21 December 20185 January 2022

Scientists map thousands of microearthquakes in Oklahoma to take a closer look at the seismic effects of wastewater injection following oil and gas operations.

Recent studies show that fluid injection wells like this one can affect seismic activity far from the injection site.

Fluid Injection Wells Can Have a Wide Seismic Reach

by S. L. Peterie, R. D. Miller, R. Buchanan and B. DeArmond 17 April 201813 January 2022

High-volume fluid injection can cumulatively increase underground pore pressure and induce earthquakes in regions unexpectedly far from injection wells, recent Kansas studies show.
