Abstract
Nowadays, microseismic monitoring has been utilized widely to detect fractures and permeability zones in many geophysics applications for exploration: geothermal resources, unconventional hydrocarbon resources, and many else. It is required to process microseismic data effectively and efficiently, but, integrated software for microseismic data processing is not available yet. We developed GMSTech (Ganesha Microseismic Technology), a Windows C# language based software which integrates complete functions and modules for microseismic characterization. In this paper, we discuss an implementation of one of the modules which can be used for calculating microseismic event source parameters: focal mechanism, using data recorded in the certain geothermal field. For estimating the focal mechanism, we developed a new simple algorithm based on grid-searching, clustering, and statistical analysis. In the results, our modules have successfully calculated the source parameters, and it is reliable for geothermal exploration. However, several factors such as coverage and number of stations may influence the results significantly, and moreover, this preliminary results still require further validation. Nevertheless, the GMSTech shows a remarkable performance, and it is more practical to be utilized for industry purposed compared to other software.
