The geothermal field in Indonesia in its development is still relatively insignificant compared to the oil field. This is due to the uncertainty of drilling in geothermal wells compared to oil wells. This uncertainty comes from the assumption of the number of wells, electrical power, and costs incurred related to the drilling. Therefore, for its development, we need field statistical data in Indonesia. The study was developed to determine the estimation of the number of wells, initial potential, drilling depth and duration of work for a well. The results of this study are then expected to be the basis of field development assumptions. From the graph of the development of a field it can also be seen that drilling activity in a field looks relatively up compared to previous years. This can be seen from the increased depth and reduced duration which indicates that the drilling is more efficient. However, this significant development only occurred at the beginning of work from the field. This is because significant developments only occur between exploration wells and production wells. From the field data above we can obtain what is the average value for exploration wells and development wells. The number of wells, initial potential, and speed of drilling are the values to be obtained from this study. Another result that can be obtained from the initial potentital statistics of each well, the value of P10 is 1 MWe, the P50 value is 7.5 MWe, and the P90 value is 21.2 MWe.
