The major objectives of interference tests are to determine whether two or more wells are in pressure communication (i.e. in the same reservoir) and when communication exists, to provide estimates of the transmissivity (kh) and storativity (Ýcth) in the vicinity of the wells. An interference test is conducted by producing or injecting at least one well (the active well) and by monitoring the pressure response in at least one other well (the observation well). The pressure response is then analyzed by comparison with theoretical models to obtain the necessary results. This paper presents the results of interference tests conducted in the Malitbog sector of the Tongonan geothermal field. The first test results gave a linear pressure response, indicative of flow in fractures. The second test results followed the Theis or radial flow solution. The results of the tests indicate that very permeable flowpaths exist within the Malitbog sector, with transmissivities greater than 50 dm and storativity values of 1.5 - 7.5 x 10-4 m/kPa.
