A study was conducted of the effectiveness of methods for increasing the productivity of uranium through preliminary forecasting. The objective of this study is to analyze and optimized the technological block currently in production. To analyze the performance of a block or cell different performance indexes are used: Tracer cut, Tracer in Place, Acid in place. Several scenarios of optimization have been tested using the HYTEC reactive transport program and modeling the uranium mining process. These scenarios involved new wells and the impact of "chemical well treatment" that increases the productivity of well. This work focused on improving the production of block. Three different scenarios were performed. Among the three scenarios, the third produced the highest amount of uranium 133 tons out of 154 tons of reserves. During optimization it is better to get the right efficiency value for each well's last trend in the cleaning action excel file. After chemical treatment of the well it was possible to increase the area where pH<1.85. This shows the importance of optimization and chemical treatment of the well.
