| Abstract | Field monitoring and testing have been undertaken in the Tongonan Geothermal Field since the commissioning of the first 112.5 Nw last March 1983. Well performance and early exploitation data show the c!ianging phases of the geothermal fluid caused by exploitation. An increasing enthalpy and chloride brine in production wells is a general feature in the field. Apparently, because of the two phase condition, the pressure drawdown is only localized and has not been significantly observed at the center of the field. Indications of slight reinjection returns are noticeable but is not a major feature in the production wells. This paper will discuss theinitial exploitation response of the wells which are drilled through a section of two phase and single phase liquid dominated reservoir of Tongonan. |
