Abstract The goal of this study is to propose a predictive model for earthquake frequency at the Azle area, North Texas using detailed fault slip modeling and coupled fluid flow and geomechanical simulation...

.... The distribution of microseismic earthquakes that are generated during hydraulic fracturing is traditionally used as a proxy to estimate stimulated reservoir volume (SRV). For efficient extraction of oil and natural gas, it is extremely important to get an accurate estimate of the SRV. However, a simple energy...

.... By analyzing the inverted source mechanisms, the 17 induced events can be classified into two main groups. Group one consists of N-S (or E-W) trending strike-slip earthquakes, while group two consists of NE-SW or NW-SE trending oblique slip events. In the case of group one, decomposition of the source...

... Abstract Seismicity induced by the waste water injection has become an important issue in the recent years, including several regions in United States, such as Oklahoma and Texas. However, many techniques that are used to evaluate whether a particular earthquake is induced or natural...

... Abstract Earthquake activity in Texas has increased from its historical rate since 2008. Seismic activity is a natural occurrence that may be hastened by human-induced changes in the subsurface, such as by injection and extraction of fluids. Subsurface in-situ conditions and the potential...

The time of occurrence of these observed LPLD events have no temporal correlation with the events reported in the regional earthquake catalogs and data from CEUSN stations, suggesting...

... related activities. In particular, there is concern that the energy that goes into the subsurface during hydraulic fracturing is sufficient to cause felt earthquakes. In many cases, it was assumed that something was safe if it was designed according to some generally accepted engineering code or guideline...

... of established stress fields can in some cases cause earthquakes. Because many of these operations are based in historically seismically quiescent regions, even magnitude 3–5 earthquakes may cause significant damage that can no longer be ignored. The public's perception, and media's coverage, of this phenomena...

... seismicity is primarily because of pore pressure increase which can lead to fault slippage and triggering of earthquakes. Simple predictive models of induced seismicity have been recently developed to relate potential maximum magnitude of the seismicity to the volume of fluid injection (e.g., Shapiro et al...
