Also this qiz is a dilemma,
Many opinions but for me i use id of last casing divided by 2.
Because i think the flow from the whole reservoir to internal casing radius.
At the end of day it doesn't affect the results.

103 ft net pay thickness not a perforated interval.
Net sand multiplied by N/G

Net sand * N/G ??
Do you mean Gross Zone for layer * N/G or Net Pay for Layer * N/G ??

for Example i have table for one layer
Gross = 12.5m , Net=8.99m, N/G=71.9%

as your mention pay zone = Net * N/G so 8.99* 0.719 ?? or 12.5*0.719 so the result will be 8.99m ??

N/G means Net to Gross,

In your case N/G is 0.719

But if you have the net pay you can use it directly into Saphir which is 8.99 m
