Depressurization Checklist<br />
• Can you depressurize below hydrate formation conditions?<br />
• If YES, can you depressurize in late-life at high water cuts?<br />
• If YES, can you maintain pressure below hydrate formation conditions<br />
during restart?<br />
• Difficult for deepwater<br />
• If YES, is there a pour point concern?<br />
• Depressurization increases restart pressure requirements<br />
• If NO, consider the following for hydrate prevention:<br />
• Displacement (dual flowlines)<br />
• Active heating<br />
• Continuous chemical inhibition
