Production in the liquid-dominated Chingshui geothermal field is largely from a fractured zone in the Jentse Member of the Miocene Lushan Formation. The geological data strongly indicate a possibility of linear-flow geometry on a field-wide scale. This was confirmed by re-analyzing the results of a multiple-well interference test performed in 1979. Radial and linear-flow models were used in this process. An evaluation of computed reservoir transmissivities and well capacities indicated that a linear model fitted the interference test data significantly better than a radial model. The linear-flow model that was developed for the Chingshui reservoir was also instrumental in obtaining an improved estimation of the geothermal fluid reserves (i.e., fluid-in-place).
