In situ stress and active faulting in Oklahoma. Development of a detailed stress map of Oklahoma for avoidance of potentially active faults when siting wastewater injection wells. Numerical simulations show that the injection of large volumes of fluid into the Arbuckle group tends to bring the part of the Wilzetta faults in Arbuckle group and basement into near-critical conditions.Īlt II, R. Given the data-limited nature of the problem, we have considered multiple plausible scenarios, and use the available data to evaluate the hydromechanical response of the faults of interest in the study area. This study provides a 3D fully coupled poroelastic analysis (using FLAC3D) of the Wilzetta fault system and its response to saltwater injection in the underpressured subsurface layers, especially the Arbuckle group and the basement, to evaluate the conditions that might have led to the increased seismicity. The seismic activity has been attributed to slip on the Wilzetta fault system. On, an M w 5.7 earthquake occurred in Prague, central Oklahoma with a sequence of aftershocks. For example, three significant earthquakes (~ M w 5) occurred near Prague, Oklahoma, in the U. From 2009 to 2017, parts of Central America experienced marked increase in the number of small to moderate-sized earthquakes.
