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
