Late tracer data and swept volume prediction using peak tracer concentration

Interwell tracers help us understand flow patterns within the reservoir and in getting reliable information of the reservoir continuity. Thus, one can obtain different information about the reservoir barriers, fractures and productivity from the amount of tracer produced at each tracer. The main objective of this study is an attempt to model interwell connectivity by analytically calculating missing tracer data in oil fields for the next step of the calculation of swept volume. The feasibility of using analytical solutions to estimate early data and check differences was carried out. In general; all of these applications refer to the applicability and relative ease of using tracers in oil field. The idea is to determine if it is possible to get a good estimate of the swept pore volumes at an early time before the tracer flood is finished since it often takes a long time to capture the complete tracer tail and there is great value in being able to get an early estimate of the results Results indicate that the extrapolation of tracer tail and using the residence time distribution method give accurate sweep volume predictions without the need to wait for long times to get the full tracer profile.
