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

Figure 5

Tracer responses after tracer injection. (a) The buffer tank was disconnected. (b–d) The air thickness in the buffer tank was modified from 17 to 39 mm. The colored plots indicate observations. The peak concentration time is indicated for each channel. The broken lines indicate simulations for channels 2 and 3, which refer to observation for channel 1 as an upstream boundary condition. The apparent tube inner diameters were determined from the estimated flow velocity and volumetric flow rate (Table 1).
