Agenda

• Conventional approach• Perforate everything• Maybe perforate in

sequence

It’s complicated

• 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

A more intelligent approach to well management

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
