Abstract

To clarify validity of an evaluation method using reservoir simulators, an application survey is made in the Oguni area, Kumamoto Pref. The observation analysis continued since 1990 revealed that there is a wide high water-permeable zone in the reservoirs north of the area. Also, data on pressure interference tests performed by combining production well and injection well confirmed that there is a non-permeable zone which divides the reservoirs between south and north. The fluid geochemical analysis makes grasp of fluid flow tighter. It was found out that there is a possibility of more than one heat history in the area, from the distribution of two peaks of the fluid inclusion filling temperature. Reservoir models by the thermal water single-phase simulator agree well with the measured temperature/pressure. Steam-thermal water two-phase state concept models by the gas-liquid two-phase simulator are well correspondent to the measured shallow-area temperature/pressure interference test data. By these natural state reservoir models, the overall production predicting evaluation is made possible. Moreover, by fracture models, a behavior of fractured reservoirs can be quantitatively evaluated. 32 refs., 110 figs., 27 tabs.
