A 40-micron produced water filter downstream of the skimmer was experiencing frequent clogging caused by sand production. Events
were occurring on average five times per month, despite filters normally being changed approximately every two months.
The recurring events resulted in well deferment, additional labor for repeated filter changeouts and increased pressure on filter
inventory. Before AI monitoring was introduced, the team had no advance warning that a clogging event was developing.
VROC trained a Time to Failure model using several months of historical operating data containing previous clogging events.
Rather than relying on a single filter measurement, the model learned patterns across available subsea and process parameters e.g.
risers and manifold pressure, in absence of sand-related monitoring devices e.g. sand monitoring, Acqustics etc.
The initial operational objective was 24 hours' warning. Once deployed against live data, the model successfully provided two days'
lead time before clogging events.
The model detected operating patterns associated with previous sand-clogging events and identified increasing event probability
before the filter became restricted, providing the operations team with time to prepare for intervention.
Advance maintenance planning
Two days’ warning enabled filter changeouts to move from an entirely reactive activity toward
planned intervention.
Reduced operational disruption
Earlier warning created the opportunity to manage clogging before it contributed to well
deferment and associated production disruption.
Improved resource planning
Predicting upcoming events can reduce unnecessary labor pressure and support better
management of replacement-filter inventory
VROC learns the patterns leading to recurring process and equipment events, giving teams more time to plan maintenance, resources and operational response.
