Black Oil System: Cold Restart • Achievable restart rates determined by: • Shut-in conditions • Fluid GOR • Water cut • Hydrate inhibitor • “Rule of Thumb”: Greater inhibitor injection rates result in lower overall inhibitor volumes used during restart • Small tiebacks: 5-10 gpm / well • Large deepwater: 25+ gpm / well • Warm-up trends: • Wellbore: Very quick (
