摘要:AbstractUnplanned maintenance interventions of subsea oil and gas production systems are very expensive, which leads to strict requirements to equipment reliability Without a systematic way to ensure reliable operation however, a very conservative operational strategy is often chosen, which can lead to sub-optimal operation and the loss of large potential profits. We propose to integrate condition monitoring and prognostics into the production planning problem to reduce conservativeness by actively steering plant degradation and preventing violation of health-critical constraints. We achieve this by combining equipment degradation models with regular process models and solving a shrinking horizon real-time optimization problem until the next planned maintenance horizon. A network of oil and gas producing wells with artificial gas lift, subject to particle induced choke erosion is used as a case example.
