Well Test Derivative breakdown query!
Hello everyone,
I have a question please.I have worked on Interpret ( well testing software). All parameters that we play in the software and model matching such as Non Darcy flow coefficient etc. ( quite long list).
I wanted to ask please, have any of you happened to go across any book's specific chapter etc
where each and every point in well test derivative is explained? I know main things like in early time we have WBS & Skin,
In middle times we have stabilizations and in late time we hit boundaries or acquifier.
But I was wondering if any of you knows of any reference in which they discuss each and every scenario with respect to different geologies,
with respect to different types of reservoir fluids and from where in the curve we get which parameter?
Thanking you,
Soman Ahmed

Dear Soman,
Please check Fekete or EPS charts on Welltest Analysis & Interpretations
The have curves for each case you are looking for. (Attached)
OR
End pages of SPE Book on Pressure Transient Testing by John Lee/ Well Testing by John Lee. The have similar diagnostic library.
