| Abstract | The Tongonan geothermal field is conceptualized in a three-dimensional three-layered model. The model covers 5.4 x 3.0 km of the field and is 800111 thick. A steady-state simulation was run to approximate the pre-exploitation condition of the Tongonan reservoir. Comparison of the siniulntion results with observed field pressures, temperatures and enthalpies produced a good match. Estimated permeabilities in the reservoir range from 5 to 100. md in the horizontal, and 0.05 to 5 md in the vertical directions. A natural upflow of 25 kg/s is also estimated near the Sambaloran/Upper Mahiao area. With the completion of the steady-state simulation of the field , modelling of its response to exploitation may now proceed. |
