Ecrin Saphir for Well Test Analysis step by step tutorial

[muhanad1992]

my point is when i finish entered all the PVT data and press okay to open new page
So and Sg are already calculated by the program and i can't change the values of them!! i can only change Sw

how can i change So & Sg

and i'm sorry for bothering you

I have no idea but the aim of this thread is how to use Ecrin.
If you have any other data we can work on it easily

thanks a lot my Friend for your help
and i have last simple question ^_^

my Q about Well radius is it bit radius , r of last casing , or r of tubing ? and why ??

Thanks in advance

[FANARCO]

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.

Hello Again

i faced many problems with Pay zone and i discussed with our Petrophysicist but i didn't get enough answer
So i want ask you about Pay zone (103 ft) in your input data, what is it represent? is it perfs interval or gross zone minus cuts off?

thanks in advance

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

[muhanad1992]

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 ??

[FANARCO]

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
