Proppant Arrival Timeline

When does each cluster's proppant actually arrive? Combines pump schedule, wellbore volume, and slip velocity (§8.11–8.12).

Pump schedule

Stage 11200 bbl • 0 lb prop
Stage 2640 bbl • 13440 lb prop
Stage 3850 bbl • 35700 lb prop
Stage 41020 bbl • 64260 lb prop
Stage 51020 bbl • 85680 lb prop
Stage 61530 bbl • 160650 lb prop
Stage 7900 bbl • 0 lb prop

Clusters

Wellbore transport

Bias exponent: 1.0 = equal flow per perf area, <1 favours heel (limited entry), >1 favours toe.

Per-cluster arrival Gantt

Each row is a cluster. The dark band shows when proppant is actually being placed at that cluster. Shorter bands toward the toe = less proppant reaches that cluster before flush.

Slip lag = MD-from-heel ÷ (fluid velocity − slip velocity). Toe clusters lag heel by 0.0 min.
