Managing the Risk of Triggered Seismicity: Identifying and Avoiding Potentially Active Faults in Oklahoma

Explore a 21-minute conference talk from the 2014 AGU Fall Meeting that delves into managing the risk of triggered seismicity in Oklahoma. Learn about the factors contributing to increased seismicity in the central and eastern U.S., with a focus on wastewater injection. Discover how in situ stress data can be used to identify potentially active faults and assess the risk of triggered earthquakes. Examine the methodology for compiling stress orientation data from wells and its application to specific fault systems like the Prague and Meers faults. Gain insights into the factors leading to large triggered earthquakes in Oklahoma, including increased injection volumes, injection into formations above crystalline basement rocks, and the distribution of injection wells. Understand the importance of stress field analysis, fault orientation, and geologic criteria in identifying and avoiding potentially active faults to mitigate seismic risks associated with oil and gas development.
