Proposed empirical gas geothermometer using multidimensional approach
- Gadjah Mada Univ., Yogyakarta (Indonesia); and others
Several formulas of surface gas geothermometer have been developed to utilize in geothermal exploration, i.e. by D`Amore and Panichi and by Darling and Talbot. This paper presents an empirical gas geothermometer formula using multidimensional approach. The formula was derived from 37 selected chemical data of the 5 production wells from the Awibengkok Geothermal Volcanic Field in West Java. Seven components, i.e., gas volume percentage, CO{sub 2}, H{sub 2}S, CH{sub 4}; H{sub 2}; N{sub 2} and NH{sub 3} from these data are utilize to developed three model equations which represent relationship between temperature and gas compositions. These formulas are then tested by several fumarolic chemical data from Sibual-buali Area (North Sumatera) and from Ringgit Area (South Sumatera). Preliminary result indicated that gas volume percentage, H{sub 2}S and CO{sub 2} concentrations have a significant role in term of gas geothermometer. Further verification is currently in progress.
