An Update on Mepas, a Software Package for Reservoir Mass and Heat Flow Characterization in Geothermal Reservoirs Using Micro-Earthquake Data

Abstract

MEPAS, a micro-earthquake analysis package, is being updated as a tool for geothermal engineers to analyze earthquakes as a mean of forecasting mass and heat flows in geothermal reservoirs. MEPAS consists of a seismic data processing part and a geological analysis part. The geological analysis part features 3D display, time and space distribution display, fracture plane extraction program, 3D focal mechanism display, display of probability of hypocenter location, etc. These functions will be useful to evaluate the behavior of geothermal reservoirs in the early stage of exploitation and to explore new reservoir around the existing reservoir. We are improving MEPAS, especially the functions of automatic hypocenter determination and the database modules. Also, MEPAAS has been converted from UNIX to Windows NT.
