I stumbled upon an article on Knowledge management and computational learning for lean energy management from the Nov 22, 2004 edition of Oil & Gas Journal.
Energy industries are using a range of new knowledge management techniques to improve the efficiencies of their operations.
Sadly, I can't get this article until it is published (no subscription). But I do want to mention that OGJ has published a number of KM-related articles over the years. Time to visit my friends at the Northwestern Library.
