Plugged Wells and Reduced Injection Lower Induced Earthquake Rates in Oklahoma

Difference between pre-plug back and post-plug back depth for wells that were initially injecting into the Precambrian basement or lower Arbuckle. Inset shows the location of these plugged back wells (colored triangles) and other disposal wells (grey triangles) within area of interest. Inset cross-section shows schematic of a disposal well that was plugged back out of the lowermost portion of the Arbuckle. | Skoumal et al. (2024) TSR
