Well Logging

[bkamali]

Hi All,
I am in process of designing a system to read the information from wells and log them in computer.
I need the followings:
1) What parameters are normally being logged in wells?
2) Who are the main manufacturer of such systems?

Any other idea about such project will be warmly welcomed.

Thanks in advance.
