Joint Diagnostic Approach to Pressure and Tracer Responses from Reservoirs: An Experimental and Theoretical Study to Estimate the Accuracy of Reservoir Models

Figure 8

(a, b) Tracer responses at the monitoring well (M) on different scales and (c, d) tracer concentration distributions along the known layer from the reinjection well (R) through the unknown fault and monitoring well after 168 and 300 d (68 and 200 d after tracer injection) for models 1–4 (Figure 6). The tracer was mixed into the injected fluid after 100 to 101 d since (a) starting injection. The travel time was estimated from the (b) peak concentration time.
