What is Value?

Value - Defined as “The material or monetary worth of something”. Maximum Value - the correct development, chosen first time,

right-sized

Inefficiency – Defined as “the magnitude of the value that can be lost” Risks not clearly identified and resolved

Value Destruction – an example

200 MMbbl of recoverable oil

No sales gas product

1200 m water depth

Fast track project (36 months to first oil)

25 year production life

Oil price of $100/bbl

Inflation at 2.5%

200 MMbbl of recoverable oil

No sales gas product

1200 m water depth

Fast track project (36 months to first oil)

25 year production life

Oil price of $100/bbl

Inflation at 2.5%

Page 6: The Importance of Integration of subsurface with surface facilities design

Initial production plateau not achieved Only 65% of intended production for 3 years

Production Profile

Same total oil recovered, but slower rate of recovery

Page 7: The Importance of Integration of subsurface with surface facilities design

Pre-Tax NPV

Missed Plateau Value Impact

Original FDP Missed Plateau

NPV, MM$ 4,074 3,621

Delta, MM$ - -453

Delta, % - -11.1%

IRR, % 22% 20%

Page 8: The Importance of Integration of subsurface with surface facilities design

Additional Production and Water Injector wells needed after only 2 years of operation

CAPEX required for drilling, equipment procurement and installation. (Loss of production during installation/hook-up/commissioning is ignored)

Additional Wells Value Impact

Original FDP Missed Plateau Extra Wells

DRILLEX, MM$ 1,600 1,600 2,400

CAPEX, MM$ 3,220 3,220 4,220

Total, MM$ 4,820 4,820 6,620

Delta, % - 0% +37%

Page 9: The Importance of Integration of subsurface with surface facilities design

Pre-Tax NPV severely eroded

IRRs remain attractive(IRR by itself is not a reliable indicator of good/bad project)

Value Impact

Original FDP Missed Plateau Extra Wells

NPV, MM$ 4,074 3,621 2,075

Delta, MM$ - -453 -2,000

Delta, % - -11.1% -55.2%

IRR, % 22% 20% 16%

Who are OPC? We are a specialist supplier of subsurface engineering, geosciences and production technology expertise globally for over 25 years. OPC offices – London, Aberdeen, Stavanger, Houston, Astana, Doha & Basra.

The strategic partnership with INTECSEA /WorleyParsons is designed to allow proper integration of predictions of the behaviour of the sub-surface with surface facilities design.

Our aim – a fully integrated Reservoir to Market (R2M) full field development planning platform

Integrating reservoir understanding (OPC Group)… with surface facilities design (WorleyParsons Group)

The importance of integration of subsurface with surface facilities design

Communication – passing the right information at the right time and using the right vocabulary.

Management of uncertainty – designing for robustness not optimisation Front-end loading of facilities design – ensuring all the appropriate

options are considered.

Adapting to a new world…

Many plans developed in the context of $100 oil no longer make sense. Assets still need to be monetised and revenue needs to be generated. In

many cases, this is still possible but requires a fresh look at the development.

OPC and INTECSEA/WorleyParsons can help companies to carry out Prospect Re-framing (PReF) by stepping back and taking a completely new, holistic view of developments against the backdrop of… $50 oil Low appetite for risk
