In deepwater subsea systems, solids deposition often develops quietly until intervention becomes unavoidable.

This customer success story shows how a Gulf of Mexico operator replaced reactive flow assurance with proactive, model-driven surveillance, reducing intervention frequency and protecting production over the life of the asset.

The Challenge

Subsea tiebacks face increasing risk over time:

• Paraffin and asphaltene deposition

• Rising pressure drop

• Frequent pigging and shutdowns

• Lost uptime and higher OPEX

Waiting for problems to surface is costly.

The Shift

Instead of reacting, the operator implemented:

• Long-term OLGA-based surveillance

• Performance-based monitoring tied to real data

• Model-driven operating and pigging decisions

The result was earlier insight—and fewer unnecessary interventions.

The Results

• Extended time between pigging runs

• Fewer unplanned interventions

• Optimized chemical use

• Improved uptime and production reliability

• Lower solids-related operating costs

This wasn’t a one-time study—it was a lifecycle flow assurance strategy.
