Well testing is giving a disturbance to reservoir, which can be conducted by producing fluid from reservoir or injecting fluid into reservoir, so there is pressure change in the well during disturbance. If pressure change is measured with function of time, then reservoir characteristics can be determined. In this paper, two vapor-dominated geothermal well is reviewed based on from fall-off test data and production data. Permeability-thickness or transmissivity from these wells is determined in this paper. In this paper, the writer determine transmissivity or permeability-thickness from geothermal wells with Horner Plot from fall-off test data, application from Fetkovich decline curve analysis based on production data and utilizing software Well Test Analysis from fall-off test data. The goal of this paper is determine if these wells are productive or not productive. This review shows different transmissivity values with range 1-2 D.m from Fetkovich method, 4-11 D.m from Horner Plot and 5-13 D.m from software Well Test Analysis. From the productive geothermal wells usually have transmissivity value about 10 D.m, these wells can be classified as fair productive.
