in stage 4, which was selected because experience shows that stress shadowing takes two or three stages to develop, and because stage 4 did not communicate to any previous stages. The image also demonstrates the general heel bias for dominant fractures that was persistent in all stages. Another observation from the frac model is that near-wellbore proppant concentration at the end of the job following diverter placement was not significantly improved over the near-wellbore proppant concentration observed at the end of the first or second sand ramp. In fact, there was a tendency to develop excessive and potentially undesirable fracture length and/or height as the result of continued injection into the same dominant fracture. Figure 6B shows the modeled proppant distribution for cluster 3 of stage 4. The top left shows distribution after the first treatment ramp, the middle figure shows the distribution after the first diverter drop and second treatment ramp, and the bottom right shows distribution at the end of the stage after the second diverter drop and the third treatment ramp. Proppant concentration again is scaled from 0 (green) to 4 (purple). FIGURE 6A End-of-Treatment Proppant Concentration Distributions For Stage 4 Clusters Interesting Outcomes DAS/DTS fiber data indicated one or two dominate fractures per cluster, and this behavior was mimicked by the fracture modeling, although predictions of the dominant cluster varied. That variation most likely was the result of actual perforation completion efficiency in the wellbore versus ideal completion efficiency
