Abstract
The Cianten Caldera in Indonesia is immediately adjacent to the producing portion of the Awibengkok geothermal field. The Cianten Caldera contains rocks similar to those in the Awibengkok field, however, the Cianten Caldera is not capable of producing geothermal power on a commercial scale. The Cianten Caldera has been microseismically monitored along with the producing Awibengkok field as injections and fracing in that field have occurred. This microseismic data is analyzed with Multi Window Time Lapse Analysis (MWTLA) to find values for the scattering coefficient, go, and the seismic albedo, [Beta]o, of the Cianten Caldera. The scattering coefficient describes the amount of seismic energy that is attenuated due to the wave scattering off of heterogeneities and the seismic albedo is the ratio of the amount of scattering to the total amount of attenuation that includes both scattering and intrinsic attenuation. This information has been combined with the geology of the Cianten Caldera to define the interior features of the Cianten Caldera and which of these features are preventing the Cianten Caldera from being a productive geothermal energy source
