Fig. 8. Distributions of (a) bromide and (b) MS-2 with increasing lateral distance from the dyed fractures shown in Fig. 5. Tracer distributions are shown for the Cr1 and Cr2 horizons only because tracer distributions in the BCrt horizon are similar to those in the Cr1 horizon, and tracer distributions in the Cr3 horizon are similar to those in the Cr2 horizon.
