This NRAP tool is for optimal design of microseismic monitoring network using surface or borehole geophones. User inputs include 1D/3D velocity models, the geophone distribution area, and a target-monitoring region. The tool varies the geophone density in the geophone distribution area, and calculates the standard deviation errors of microseismic event locations as a function of the numbers of geophones within the geophone distribution area. The turning point of the curve of the standard deviation error versus the number of geophones corresponds to the number of the geophones and their distribution for optimal/cost-effective microseismic monitoring. This NRAP tool enables field operators of geologic carbon storage to design optimally a microseismic monitoring network using surface and/or borehole geophones for cost-effective microseismic monitoring.
The tool can run on Linux, Mac, and Windows operating systems (OS). After obtaining the latest build of the GUI w/logic PSMT_rcxxxxxxxx.zip, unzip/decompress the file in the designated directory to install the tool.
To run the GUI w/logic on Linux, Mac, or Windows OS, open up a command line terminal/console window and navigate to the root directory of the application, and run the java command to start the GUI: ” java -jar NRAP_PSMT.jar ”.
