| Abstract | Because of the relatively long history of exploitation of the Wairakei geothermal reservoir and the ready availability of data it has frequentl y been used as a test case by geothermal modellers. The models of the Wairakei reservoir considered have ranged from simple lumped parameter models Fradkin, Sorey and McNabb to quite extensive multi-dimensional distributed parameter models Mercer and Faust and Pritchett, Rice and Garg. efforts have been extremely useful in developing an understanding of the physical processes of major importance at Wairakei. The models developed by McNabb Grant Wooding (1981) and Pritchett et (1980) are particularly important in this respect. produced a model of Wairakei which is capable of giving fit to the past history of the main reservoir parameters, say pressure decline and production enthalpy, and which is sufficiently robust to be used for predicting medium-term and long-term future behaviour. Probably the best pressure-matching model is that produced by et decline curve model with parameters selected using ca ted system-identification techniques but is related to the earlier model of McNabb which is based on real physical processes. |
