Readme for calculataed TOC LAS files


The LAS files contain 6 curves:

1) Depth - Measured Depth

2) VCLGR - Volume of Clay

3) VCoal- Coal indicator either 1 (coal) or 0 (no coal).

4) TOC avg- Average calculated total organic carbon curve

5) TOC min - Minimum calculated total organic carbon curve

6) TOC max- Maximum calculated total organic carbon curve



-Null values: -999

-The calculated TOC curves are nullified whenever the VCl< 0.5 and/or VCoal=1.

-The depth intervals are of Carboniferous and older. 

-The curves were calculated using the inbuilt TOC tool in Interactive Petrophysics (IP) (TM)
