Nelson Index  Filed Under: , Dictionary Says  Definition of
'Nelson Index'  The Nelson Index is a measure of the complexity
of an oil refinery. Refineries that are higher on the Nelson
Index are valued higher relative to their peers. For example,
high Nelson Index refineries may be able to refine lower quality
crude oil, or be capable of producing higher value end products.
Due to their greater complexity, high Nelson Index refineries
are more costly to build and operate. Investopedia Says
Investopedia explains 'Nelson Index'  The Nelson Index was
developed in 1960 by Wilbur Nelson. Since the details of how a
refinery operates are difficult to comprehend without
specialized industry knowledge, the Nelson Index provides an
easy metric for quantifying and ranking the complexity of
different refineries. Based on the Nelson Index, on average,
U.S. refineries are the most complex in the world. However,
there are an increasing number of highly complex refineries
located in other countries.  Articles Of Interest
