This paper presents the application of a new concept of fractal model for analyzing pressure transient test data in a complex naturally fractured geothermal reservoir.Application of conventional type curves has been unsuccesfully in analyzing and interpreting the interference test results in Kamojang geothermal reservoir which is considered as a complex naturally fractured system. Using the conventional type curve method, the pressure test data, in this case, can not match to the curve, primarily at early time data. The match, however, can be achieved by using the type curves generated based on ",fractal reservoir model", which has been developed in this study. Using the diffusivity equation of fractal reservoir, the equation for interference test has been derived and the result is then used for generating a new type curve method. In addition, the procedure to use this model has also been developed.Using the generated type curves, application has been performed on analyzing the interference test data from Kamojang geothermal reservoir. The analyzing results demonstrate the viability of the model in describing characteristics of the reservoir such transmissibility, storativity, and fractal dimension of the medium.
