Xodus DevelopWhat we do
Identifying and defining optimal concepts that create value and achieve business goals
Appraise / Select (Concept Screening)
> Understand opportunity, look wide
> Understand uncertainties
> Identify at least one feasible concept across TECOP
> Identify decisions for development
> Identify major risks> Field redevelopment /
re-engineering
Concept Select
> Evaluate all concept decisions and select optimum concept
> Optimum concept is not just technical, but optimum across TECOP
> Evaluate major risks
