GeoEMS brings low cost solutions for seismic monitoring systems

Low Cost

Our low-cost seismic monitoring model deploys a single monitoring station near an injection well or grouping of injection wells. Although seismic event location cannot be accurately determined using a single monitoring station, distance of the event from the station can. This information can be critical in determining if a seismic event was likely to be caused by the injection process being monitored. Event location using regional networks, such as provided by the USGS, can have errors of many kilometers. Consequently, the single station near the well is the only data that could be used to identify a significant location error.

Micro-seismicity Rates

The single station can also be used to determine baseline seismicity as a function of distance from the station and any changes in seismicity rates as injection processes are changed. Such micro-seismicity will generally be far below the detectable magnitudes from regions networks and provides the only data source for understanding how the injection process is changing micro-seismicity rates.

Seismic Stations

If a company has multiple SWD wells in an area, we combine the seismic stations into network and provide seismic locations for the events recorded at multiple stations. We also include data from any open seismic networks located in the vicinity of the SWD wells.
