| Abstract | Kamojang geothermal field has been in operation for nearly 30 years. One effort to maintain sustainability of geothermal resource in the reservoir, Kamojang geothermal field carried condensate reinjection through reinjection wells. One of the key success in managing reservoir is one of them by knowing the pattern of fluid flow reinjection. Several attempts were made to determine the flow pattern or connectivity between reinjection wells and production wells, one of which is using micro earth quake monitoring. A 11 station network of three-component digital seismometer at Kamojang geothermal field, Indonesia was deployed since 2010. By observing microseismic activities it was hoped that orientation of reinjected condensate path would be indentified, in addition tracer test was also conducted to further ensure reinjected condesate path and connectivity between the reinjection and production wells. |
