How to Migrate Scenario Level Extractions

From Enersight version 2.14 onwards, scenario level input of extraction and yield information will no longer be possible due to this opaque input causing confusion within reporting processes.

When opening a project in version 2.14 onwards where such inputs exist, a dialog box will appear to advise that these details have been removed.

This topic outlines the process of modifying the model to re-introduce the extraction within an acceptable and clear method based upon an example setup. This project has few simple networks with 10% fuel applied at the scenario level.

For this network, there is a sales point included in the network, essentially making it upstream of the scenario. This creates confusion in reporting as normally there is a 100% match between as produced (the throughput value of the asset) and the as sold amount at the scenario level. However this setup below will result in only 3.6 bcf of the available 4 bcf being reported due to the 10% fuel.

If such behaviour is indeed desirable, this could be managed via introducing a new asset downstream of the Sales Point as per below:

In cases where there are multiple sales points, then this new facility would need to be connected to each of them (or multiple extra facilities added along with the extra data management maintenance cost).

The more normal case would be where this behaviour was unintentional and that the fuel usage should rather be placed within the network where it is actually utilized, as an example refer below, noting that now the sales point and the scenario will match results:

Whilst this example has concentrated on the Fuel shrinkage case, similar actions could be repeated if gas component extractions or yields of NGLs were also involved.
