The PI System for a Deepwater Oil &

Gas Field

Africa’s leading independent oil company

Deriving value from a digital oilfield solution for a

deepwater oil and gas field

Designing and building a

digital oilfield solution with

no previous experience

Use of the PI System as the

core data repository and

feed into other systems

Optimisation of production

that would otherwise not

have been possible

• Cross-functional team

• Integration of key business

applications via PI System

• Real-time well models – saving $M’s on MPFM maintenance

• Automated workflows saving time and effort

• Problem investigation and resolution

• Short timescale – 12 months

• Remote – 50km from shore

• Deep water – 1200m
