The Juran Hydrocarbons Index ® (JHI) is a proprietary (patent pending) methodology of Juran Institute. The Index has been developed by Angel Tonchev and Christo Tonchev to address some of the limitations of existing oil & gas performance measurement practices. It is a cumulative indicator of the overall competitiveness of an asset (i.e. platform, pipeline, marine terminal, refinery and etc.), based upon efficiency and effectiveness of its performance. It is a numerical value representing the percentage deviation of performance, relative to the corresponding industry or peer group average. For example, if a particular asset has a JHI equal to 10, this would indicate that its performance is 10% better than the average performer. If the calculated JHI is a negative number, it indicates that the performance is worse than the average industry standard.
