Abstract of the presentation:

A central concept guiding the merge of Statoil?s and Hydro?s G&G data has been the idea of identifying all of the ?versions of the truth? for each data item, ascertaining the reliability and accuracy of each, ranking them, then choosing the ?best version? and flagging it as such. This is about as far from being a simple data transcription as you can get. This philosophy has a profound effect on both the challenges and the technical solutions chosen. In truth the philosophy generates many of the challenges and adds to the complexity of the technical solutions however the end result is a single data set of much higher quality and value than either of the input data sets.
