AI for reliability in CSG wells: accelerating equipment failure diagnosis and business performance

Shell QGC continually seek to lift production while lowering unit operating cost (UOC). At QGC, unplanned downtime in hydraulic power units (HPUs) is a major driver: across a large wellsite fleet, more than 10,000 unplanned HPU trips occur annually. Each trip triggers a corrective maintenance (CM) work order (WO), yet diagnosis often becomes a hit and miss exercise due to limited historical failure data and incomplete digital symptom mapping. Traditional diagnosis relies heavily on complex datas
