| Abstract | Manual calibration to adjust parameters to produce a model that best represents the actual behaviour of a geothermal system is a tedious and frustrating process. This paper discusses automatic calibration of a geothermal reservoir model employing inverse modelling techniques. Inverse modelling simulators, namely PEST and iTOUGH2, are utilized to identify the values of parameters that achieve the best fit between the model results and the measured data for the natural state of Lahendong geothermal field. There were two aims for the project: first, to develop an improved model of Lahendong, and second to establish good, general protocols for inverse modelling of geothermal reservoirs. |
