What have we learned?<br />
MEG Loop<br />
•MEG Loop<br />
– Continuous “circle”<br />
• MEG injected at templates<br />
• Recovered at facility<br />
– Lean MEG:<br />
• “lean in water” typically 90% MEG<br />
– Rich MEG:<br />
• “Rich in water” typically 60% MEG<br />
•MEG Recovery<br />
– Recovered by distillation<br />
• Evaporation dem<strong>and</strong>s a lot of energy<br />
– Regeneration; Only water is removed<br />
• MEG loop will be “polluted” over time<br />
– Reclamation; water <strong>and</strong> MEG evaporated<br />
• Salt etc. can be removed<br />
• Can control “pollution” of MEG loop<br />
– Expected amount of formation water dictates which<br />
type of facility (or combination) that is needed<br />
