Black Oil System: Cooldown • Shutdown statistics • Typical shutdown durations • 89% shutdowns < 10 hours • 94% shutdowns < 12 hours • 99.9% shutdowns < 24 hours • Typical shutdown causes Pumps Scale Corrosion Sand Paraffin Hydrates Asphaltenes Separation Other
Black Oil System: Cooldown • Planned shutdown Procedure • Inject hydrate inhibitor for one residence time (minimum) • At high water cuts, may need to reduce flowrate to effectively treat system • Inject hydrate inhibitor into subsea equipment • Particular attention to horizontal components • Self-draining manifold / jumpers • Treat upper portion of wellbore • SCSSV vs. top ~50 ft • Shut-in system
