SCHEDULE Motivation and Objective An Overview of PETROBRAS Upstream Business Segment Risk Analysis in Upstream Projects at PAI Real Options in Upstream Projects The US Gulf of Mexico Case Conclusion and Final Remarks 3
MOTIVATION AND OBJECTIVE Motivation: All investment projects at PETROBRAS must undergo economic risk analysis There is a standard model for economic risk analysis of upstream projects at PETROBRAS AMERICA INC. Since in the US a continuously producing lease does not expire, upstream projects in the US Gulf of Mexico have natural expansion options! But our risk analysis model does not evaluate real options! 4
MOTIVATION AND OBJECTIVE Objective: Briefly present PETROBRAS Examine the risk analysis model used for upstream projects at PAI (using @RISK) Develop a Real Option model for the expansion or phasing of projects Present a solution integrating the standard risk analysis model (using @RISK) and the Real Option model (using RISKOptimizer) Present an example using the real option model in an upstream project on the US Gulf of Mexico 5

Real Options in Upstream Projects 15
MANAGERIAL FLEXIBILITIES AS REAL OPTIONS IN UPSTREAM PROJECTS Upstream projects typically have many managerial flexibilities: Waiting for the (irreversible) decision to invest in the project Early Options Investing in more information Phasing the project Investing in additional production/injection wells Later Options Temporary shut down the production Abandonment of the project Expansion (lifetime) of the project 16
ABANDONMENT OF THE PROJECT AS A REAL OPTION Every production project has an Abandonment Phase, according to the production equipment designed lifetime Yet, adverse economic conditions might destroy all value of a fully developed project. In some scenarios, lifting costs might even top Oil prices! If taking into account all risks and flexibilities the expected value of continuing production is negative, the company may decide to abandon the project earlier than originally intended To continue producing up to the Abandonment Phase is an option, not an obligation! Abandonment Real Option 17
ABANDONMENT OF THE PROJECT AS A REAL OPTION Oil Production vs Abandonment Year NPV Distribution WTI Price vs Abandonment Year 18
EXPANSION OF THE PROJECT LIFETIME AS A REAL OPTION According to the US laws and regulations, continuously producing leases do not expire. If successful production is established in a lease, the lessee company can keep production indefinitely. Therefore, upstream projects in the US Gulf of Mexico have natural expansion options! But the production equipment have a limited lifetime Additional CAPEX is necessary to continue production past the equipment designed lifetime To continue producing a lease past the initial lifetime is an option, not an obligation! Expansion Real Option 19
EXPANSION OF THE PROJECT LIFETIME AS A REAL OPTION Oil Production vs Expansion NPV Distribution WTI Price vs Expansion 20
ABANDONMENT AND EXPANSION AS CONCURRENT REAL OPTIONS WTI Price vs Abandonment + Expansion NPV Distribution Calculating the Real Options Premium involves finding the optimal threshold curve for exercise that maximizes the expected NPV of the project! This is the optimal decision rule! 21
ABANDONMENT AND EXPANSION AS CONCURRENT REAL OPTIONS But how do we find the optimal threshold curve for exercise? How do we maximize the expected NPV of the project? 22
The Gulf of Mexico Case 23
THE GULF OF MEXICO CASE EXAMPLE PROJECT Original Project Specs: Oil project, peak production = 35.000 bpd Production decline = 4% per year CAPEX (Initial) = US$ 3.750 MM OPEX = US$ 100 MM per year fixed + US$ 5,00 per bbl variable Lifetime (Initial) = 20 years Discount Rate = 10% Risk-free Rate = 4% 24
THE GULF OF MEXICO CASE EXAMPLE PROJECT Risk Factors: Oil production = Triangular distribution, +/- 35% Production decline = Triangular distribution, +/- 15% CAPEX (Initial) = Triangular distribution, +/-25% OPEX = Triangular distribution, +/- 15% Price Model: Mean Reverting with Jumps Initial Price = US$ 100,00 per bbl Long Term Price = US$ 80,00 per bbl Price Volatility = 25% per year Half-life = 5 years Risk Premium = 6% 25
THE GULF OF MEXICO CASE MODELING THE REAL OPTIONS Real Options Modeled: Abandonment Option American Put Expiration = 20 years Strike (CAPEX) = US$ 250 MM Triangular distribution, +/- 25% Expansion (lifetime) Option European Call Expiration = 20 years Strike (CAPEX) = US$ 1.000 MM Triangular distribution, +/- 25% Grants a new Abandonment Option 26
THE GULF OF MEXICO CASE MODELING THE REAL OPTIONS Determining the Abandonment and Expansion (lifetime) concurrent Real Options Premium involves finding the optimal threshold curve for exercise of the options that maximizes the expected NPV of the project! Which in practice means: Modeling the Real Options as decisions inside the model Abandonment = Kill all future cash flow! Expansion (lifetime) = Invest now and continue the cash flow The decisions must be consistent At the end of the primary lifetime of the project (first abandonment option expiration) the model must exercise either the Abandonment or the Expansion (lifetime) options 27
THE GULF OF MEXICO CASE MODELING THE REAL OPTIONS Which in practice means (continued): The discount factor of the project with Real Options is NOT the same of the project without options but under certain circumstances we CAN use the Risk-free rate as the discount factor! To use the Risk-free rate as the discount factor, we MUST model all market correlated risk factors in the Risk-Neutral measure Risk-Neutral Prices = Real Prices Risk Premium WTI Prices = Risk-Neutral WTI Prices Other Prices = Risk-Neutral Prices Risk factors not correlated with the market stay the same Production Curves = uncorrelated with the market CAPEX & OPEX = uncorrelated with the market 28

THE GULF OF MEXICO CASE MODELING THE REAL OPTIONS Which in practice means (continued): Creating a threshold curve for exercise to control the decision Different threshold curves yield different NPV Using RISKOptimizer to find the parameters of the threshold curve This will be the optimal decision rule! The optimal threshold curve is the one that maximizes the expected NPV of the project! The Real Options Premium is the incremental NPV of the project created by this decision rule! 30

THE GULF OF MEXICO CASE DETERMINING THE REAL OPTIONS PREMIUM Finally, to determine the Real Options Premium we must: Run the Risk Analysis of the Original Project (no Real Options) Run the Risk Analysis of the Project with Real Options The Real Options Premium is the difference of the two Expected NPVs! Both Risk Analyses must be run in the Risk Neutral measure! The Real Options Premium ONLY exists if the decision rule is strictly followed! 32
THE GULF OF MEXICO CASE DETERMINING THE REAL OPTIONS PREMIUM Original Project - No Abandonment, No Expansion Full Project - Abandonment and Expansion Options The Real Options Premium is the difference of the two Expected NPVs! RO Premium = US$ 220 MM 33
THE GULF OF MEXICO CASE DETERMINING THE REAL OPTIONS PREMIUM Original Project vs Project with Real Options 34
Conclusion and Final Remarks 35
CONCLUSION THE IMPORTANCE OF REAL OPTIONS The future is uncertain so the presence managerial flexibilities creates value for the project. It is its ability to adapt the uncertainty! Although two similar projects might have roughly the same Expected NPV, they might differ greatly in terms of managerial flexibilities! Experienced decision makers tend to see/feel the value of these flexibilities But how to measure them? How to compare different project opportunities if one can t measure the value of these flexibilities? What is the fair value of these flexibilities? How much should the decision maker be willing to pay for each flexibility? 36
CONCLUSION THE IMPORTANCE OF REAL OPTIONS Modeling the project managerial flexibilities as Real Options allows us to: Measure the fair value of the project flexibilities, its Real Options! Study the impact of the uncertainties (modeled as risk factors) over the managerial decisions available along the lifetime of the project Design optimal strategies for the irreversible managerial decisions available to the project For example, the irreversible decisions of first investing, expanding or abandoning the project Compare different project opportunities, taking into account the uncertainty and managerial flexibilities of each project Objectively integrate managerial flexibility into the valuation process, in order to improve the decision process! 37
FINAL REMARKS Modeling these flexibilities as Real Options involves: Modeling the Real Options as decisions inside the model Finding the optimal threshold curve for exercise of the Real Options Take special care with: The decisions must be consistent Use the Risk-free rate as the discount factor Model all market correlated risk factors in the Risk-Neutral measure Risk-Neutral Prices = Real Prices Risk Premium 38
FINAL REMARKS Use RISKOptimizer to find the parameters of the optimal threshold curve for exercise of the Real Options: The optimal threshold curve is the one that maximizes the expected NPV of the project! Run the Risk Analysis of the Original Project (no Real Options) Run the Risk Analysis of the Project with Real Options The Real Options Premium is the difference of the two Expected NPVs! The Both Real Risk Options Analyses Premium must ONLY be run exists if the in decision the Risk rule Neutral is strictly measure! followed! 39
