7" vs 5": casing $14 vs $12/ft & ESP $41 vs $28/stg (motors $25/hp).
TDH of 1,860' & 3,000 bbls of H20 required.

1) Given ft/stage (or on provided chart): 5" is 16'/stage & 7" is 44'/stage
2) 5" & 7" Stages: 1860'/16'/stage = 117 stages & 1860'/44'/stage = 43 stages (round up)

b) Pump: 117 stages($28/stage) & 43($41/stage) = $3M & 2M (use curves as needed).
c) Motor: 117($0.58 BHP/stage)$25/HP & 43($1.4/stage) BHP/stage)$25/HP = $2M & $2M (use curves as needed).

Total 5" or 7" Costs: $41+$3+$2 or $48+$2+$2 = $46M or $52M.
