Why is a well test validation done when saving a network version?

When a PA adds wells to an allocation network, a check is done to see if there is a well test available in the system for the wells, before saving the changes to the network. This is an important check, since not loading welltests for new wells, is very common and often takes a lot more effort to debug and detect.

Well test expectations

The validation helps to ensure the the following criteria are met:

For the products configured with “Well Test Allocation Method”, well tests are available to allocate volumes for all the wells, across the different dispositions configured.

Well test validation

When saving a network, the application performs the following validation for any product where the allocation method is well-test:

1. All the unique readings, most probably well test readings, which are configured as ratio sources for different dispositions are identified.

2. Once all the readings are identified, a check is done for availability of at least one of these readings before the “effective to date” chosen for the network version.

3. The result of this check is displayed product-wise for each well in the network-version being saved.

For example, for a network with effective dates from 10-31-2009 to 10-31-2021 (with an allocation method = well-test), at least one well reading (configured as ratio source) should be available for a date before 10-31-2021. If not, a warning is shown.
