I assume you are talking about the Nelson-Farrar Index that is published in the Oil and Gas Journal quarterly. It used to be the Nelson Index but some 10 or 12 years ago it was changed to the Nelson-Farrar Index.
You may find some info by doing a search on the OGJ website or by obtaining a copy of the OGJ. They typically have a brief discussion of their cost information in some issues or in publications that you can purchase from the OGJ.

Nelson Complexity Index is a measure of secondary conversion capacity in comparison to the primary distillation capacity of any refinery. It is an indicator of not only the investment intensity or cost index of the refinery but also the value addition potential of a refinery.

See the link for a complete discussion of the EDC which relies on the Nelson Complexity Index for its calculation.
