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.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Complete functions,Geothermal exploration,Geothermal resources,Integrated software,Microseismic events,Microseismic technology,Source parameters,Unconventional hydrocarbon resources[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors greatly acknowledge Pertamina UTC for funding the development of GMSTech.
