Good evening Azad, nice collection and thanks very much for share it.
I'm not quite sure but I believe I can get "15b. Serra - Fundamentals of Well-Log Interpretation - 2. The Interpretation of Logging Data (1986)", let me check tomorrow at work, if so let me know how to send it back to you.
One little open question, since a long time ago I'm trying to find "Properties of reservoir rocks: core analysis, by Robert P. Monicard" if ANYBODY can help me finding that book I will be sincerously gratefull.

With kind regards.
