In attempting to know the performance of wells, well testing was performed in geothermal well. Well test performed included measurements temperatur and pressure of wells, water loss test, and gross permeability test. Quantitative analysis of well testing is performed to determine estimated production and physical characteristics of the wells that can describe the whole reservoir. Estimated production using relation between injectivity and the expected maximum discharge for big hole well depends on the temperatur of the main feed. Interpretation of data from gross permeability test with saphir software is used to obtain the appropriate reservoir parameters and model to real condition. Qualitative analysis is also performed to determine feed zone and feed point of the well. Feed zone can be obtained from analysis of slope temperatur and pressure during heating up process, while feed point is obtained from analysis of water loss test graph. In addition, productivity index of feed pointcan be determined with mass balance principle. Analysis of wells obtained is used to obtain an initial estimate of the characteristics of the wells that will be used as the initial data for the next well testing.
