Short summary
We have studied the stress conditions at the Decatur CO2 storage site that would induce the observed microseismicity. Initial estimates suggested that faults required higher pressure to slip than the injection pressure, but refining pressure and friction assumptions led to more realistic scenarios. Our study highlights the importance of accurate stress state measurements and high-quality data to better predict reservoir response to injection and improve the safety and reliability of CO2 storage.
