Abstract
This paper proposes the application of decline curve analysis methodology to Cerro Prieto I geothermal field. In the visual analysis of the plot for exponential trend, an unsteady state of the reservoir was detected. Fourteen wells were analyzed and classified in three groups according to their behavior. The percentage of annual declination vas calculated in 10.678 for budgeting and planning. In the other hand, 20.99% of annual declination was calculated for vells that may need a workover.
