Sweep efficiency				Displacement efficiency	Acceleration	Cost
Optimising well-reservoir contact					Flowrates	Optimising the wellbore completion and lift mechanism
New wells	New laterals	Flow Stimulation	Flow Shut-off	Conformance control	Flowrates

The above activities are further classified into four execution mechanisms:

Subsurface		Surface
Drilling & Completion	Workover	Rate Optimisation	EOR facilities and procedures

This leads to the four major asset challenges:

1. Where to drill the new well or side-track and how to complete it ?

2. Which wells to workover and how ?

3. Which wells to change the flow rate and whether increase or decrease ?

4. What fluid to inject ?

6. If there is a bottle neck in surface infrastructure and whether it needs update ?

The answers to these questions are provided by playing the various scenarios over the calibrated full-field flow model.
