Assay Libraries

The Spiral tools are shipped as standard with the Spiral HPI assay library. Two further libraries are available for licensing, offering many more crudes and more detailed quality characterisation.

For clients who license Spiral tools, a statistical model is included with each library, containing information on the links and correlations between the various crude oil properties for the assays in the library. This can be used to reconstruct complete crude oil characteristics from any available information - whether modelling a new crude or updating the profiles for an existing database entry.
