Early in 2004, one of North America’s largest oil and gas companies decided to offer PI Historian services to each of its business units. The tag count has almost doubled in a year to 110,000 and the system has more than 36 interfaces to more than a dozen different makes of DCS/SCADA systems. The PI data is rapidly put to use in supporting various optimization, time saving, and improved decision-making initiatives. Continued adoption of PI use by additional business units and a very aggressive well drilling program are creating significant workload and administrative demands for this heavily used and constantly growing PI System. Keeping it all running reliably and adding new interfaces/tags could easily eat up most of our time and prevent us from getting the most value out of the data. A collection of applications, reports, and utilities (built with extensive use of the PI SDK) have enabled massive growth and rapid payback on the investment in PI.
