Delete run path deletes too much

equinor / ert

ERT - Ensemble based Reservoir Tool - is designed for running ensembles of dynamical models such as reservoir models, in order to do sensitivity analysis and data assimilation. ERT supports data assimilation using the Ensemble Smoother (ES), Ensemble Smoother with Multiple Data Assimilation (ES-MDA) and Iterative Ensemble Smoother (IES).

Delete run path deletes too much #8180

Open oyvindeide opened 2 weeks ago

oyvindeide commented 2 weeks ago

Describe the bug When checking the delete run path checkbox in the gui, ert will sometimes delete too much, this happens when:

Evaluate ensemble: it assumes that the starting iteration is 0, if it is used for an ensemble with another iteration, the delete will be wrong
ES-MDA restart: it assumes that the starting iteration is 0, if restarting this will not be the case.

A backport should be made to version 10.1 where we disable the button, for main we should remove this feature and reconsider the implementation.

After discussing with users, the combination of Evaluate ensemble and delete run path is a quite powerful combination, it was hypothesized that without the delete run path functionality the rerun functionality would loose a lot of value, and a complete restart would be more likely.

On further discussion this feature should stay as is, bug the bug fix needs to be backported to version 10.1
