Real-Time Compression OptimizationUsing PI AF & First Principles Models to Predict Compressor OperationsCase Study: Real-time Compressor Optimization using PI Data and First Principles ModelsCHALLENGESOLUTION Historically, we run compressorperformance curves during design andthen periodically to confirm properperformance Compression Health Monitoring Teamruns first principle models using realtime PI data. Model output is used todefine optimal compressor settings forcurrent operation. Changes in gas volume, composition,field pressures can significantly changethe optimal operating point PI Vision displays provides operatingconditions based on optimal load step RESULTSMore quickly identify optimalcompressor operatingparameters Reduced operating costs Improved equipment reliability#PIWorld 2019 OSIsoft, LLC

Linking Operational to Geographic DataUsing Operational and Geospatial Data to Optimize Gas Flow and Gathering PerformanceCHALLENGE DCP’s assets are spread over a widearea, requiring lots of driving miles foroperations and maintenance With its long distances and extensiveinterconnections, our gatheringsystem operations must considergeography of our assetsSOLUTION Linking operating data withgeospatial wellhead and gatheringsystem information will allow rapidunderstanding of issues andresponses to normal and upsetconditions.RESULTS Optimal gas routing Increased volumes Greater reliability Fewer miles driven#PIWorld 2019 OSIsoft, LLC
