In last decades a new way to interpret well performance has continuously been developed by engineers. New methods of tracer analysis consider the temporal behavior of tracers. Recent method is using tracer interpretation based on temporal moments (Shook 2005). Tracer analysis have been used to indicate subsurface performance qualitatively, whereas new method can be used to generate quantitative approach by defining the flow geometry and interwell volume using numerical methods. The method and application mentioned are all based on analysis of tracer residence times. The mean residence time, or first temporal moment, is the most useful single property derived from a tracer test. The analysis is used to identify one of Chevron’s field to evaluate the existing well and its performance. Chevron Pacific Indonesia’s (CPI) field has been producing since year 2000. Every year various of test have been conducted to evaluate their production strategy. While CPI starting to use tracer method in 2008 using temporal moment. <br /> <br /> <br /> <br /> To find out the different interpretations using temporal moments in the Water flood and Polymer-flood reservoirs, a program will be created using an excel spreadsheet based on the temporal moment interpretation made by Shook (2005). The data used to interpret the properties and characteristics of Water flood injection and Polymer-flood injection is CPI injection data conducted in 2012. Injection is done using 6 different types of Tracer on each type of injection so that differences in properties and characteristics can be seen. <br /> <br /> <br /> <br /> Interpretation results of Water flood injection and Polymer flood have significant differences. The main differences are in the number of swept pore volumes and tracer recovery that are detected on the surface. This difference can give insight into the heterogeneity of a reservoir and the flow behavior in the reservoir. Therefore, it can be concluded that the use of Tracer in Water and Polymer flood injection can help to retain reservoir characteristics so that the EOR strategy can be done well. <br />
