• Conventional approach• Perforate everything• Maybe perforate in
sequence
It’s complicated

Reservoirs are not uniform
Reservoir understanding at the start of the field life

• Drill your well• Run your production tubing• Perforate all four reservoirs
to maximise early production
• And hence revenue
• Ad hoc data collection• Deal with problems later
• Try and shut off water production
• Re-perforate if scale forms
Conventional approach to well management

There is uncertainty – and reservoirs are not uniform

• Perforate all four reservoirs• Run an intelligent
completion• Real time monitoring• Manage the problems
proactively• Prevent or defer water
production• Re-perforate if scale forms

Advantages• Better information about
reservoir performance• Greater recovery = greater
profitability• Adjust well to maximise
recovery
• Fewer production problems• Less water (can impede flow
and can kill well)• Less scale (can block flow)
Disadvantages• Higher initial cost
• Often applied to more complex wells
• More moving parts • reliability to be considered –
now largely addressed
• More sophisticated reservoir management
• Real time decision making
Making the decision to run an intelligent completion
