Starting from practical cases observed on the field, the idea was to break down different steps of a diagnostic of a well in order to setup a protocol and to help appropriate decision-making as regard technical solutions. Of course, the major question in the background remains the relevance to rehabilitate an existing well versus the construction of a new well. Indeed, in some cases, the rehabilitation may appear inappropriate because it is too costly as compared to a new construction, or too risky or because of a too low feasibility to restore the well in a correct state.
