Subsurface Hydrothermal Alteration in the Kamojang Geothermal Field, West Java, Indonesia
The presently vapor-dominated Kamojang geothermal field is located in West Java (Indonesia). The field lies in high terrain, 1500 m above sea level, and is hosted by volcanic rocks. Samples from seven wells were kindly made available for this study, namely from KMJ-7, KMJ-10, KMJ-11, KMJ12, KMJ-53, KMJ-59, and CHR-1 drilled to depths ranging from 536 – 1804 m. The reservoir is hosted by interbe...
متن کاملMicrobial Diversity of Acidic Hot Spring (Kawah Hujan B) in Geothermal Field of Kamojang Area, West Java-Indonesia
Microbial communities in an acidic hot spring, namely Kawah Hujan B, at Kamojang geothermal field, West Java-Indonesia was examined using culture dependent and culture independent strategies. Chemical analysis of the hot spring water showed a characteristic of acidic-sulfate geothermal activity that contained high sulfate concentrations and low pH values (pH 1.8 to 1.9). Microbial community pre...
متن کاملSteam-water Relative Permeabilities for the Cerro Prieto Geothermal Reservoir
We have refined a method used previously by several authors to estimate water-steam relative permeabilities. Our version provides also reasonable estimates of the corresponding saturations. It relies on production output data obtained by means of short tests. This constitutes a distinct advantage over the previous variants, which require long-term production data, because it allows early accura...
متن کاملFluorescein and Naphthalene Sulfonate Liquid Tracer Results at the Awibengkok Geothermal Field, West Java, Indonesia
An extensive program of tracer tests has been carried out to monitor the performance of the production/injection scheme in the Awibengkok geothermal field. Initially, tests using fluorescein dye were conducted in almost all of the 20 wells used as injectors. These tests yielded excellent data detailing the timing and direction of injectate flow, indicating strong lateral permeability and depth ...
متن کاملPrecise Gravimetry and Geothermal Reservoir Management
Modern portable gravimeters can routinely achieve a 5 ugal uncertainty with careful measurement procedures involving multiple station occupations in the same day, and stacking of readings over at least 15 minutes during each occupation. Although further improvements in gravimeter accuracy are feasible, other practical factors relating to repeat surveys of geothermal fields make such improvement...
