OLI Pseudocomponent and Hydrocarbon Assays
API Methods
It is somewhat difficult to find the correct version of API and the year that it was published. Here we have listed, to the best of OLI's ability, to correlate the published year with the API version number. We have not attempted to correlate the revision years.
For OLI's purposes we use API version 5.0 (1992) and 8.0 (2006) in our code.
| API Version | Published Year | Notes |
| 1 | 1966 | |
| 2 | 1970 | |
| 3 | 1977 | |
| 4 | 1982 | |
| 5 | 1992 | OLI uses this version |
| 6 | 1994 | This version does not exist in the official record. This version was bad and API pulled it. |
| 7 | 2005 | |
| 8 | 2006 | OLI uses this version |
| 9 | 2013 | |
| 10 | 2018 |
