RESUMO

The legal framework in Brazil has changed afier the 90 s towards an economic environrnent ofmore competition among oil companies in the E&P business. In this new scenario, the investment decisions must be guided, considering four important features: a) investments are, at least in part, irreversible; b) uncertainty over the future cash flow of projects; c) implications of available real options (managerial flexibilities) to adapt the project to new economic market realities; d) corporation managers are traditionally risk averse. In such economic environrnent, the traditional indicators of discounted cash flow such as NPV (net present value) and IRR (intemal rate of return) may produce divergent results from the market practices since they ignore specially the value of real options embedded in the project and also the risk preference of the decision-maker. As an altemative tool, in this work, it is developed an integrated model combining the options approach and preference theory (or utility theory). The options approach is due to the analogy of the determinants of financial and real options. The preference theory makes use of utility function of decision-maker in order to rank projects in more rational and sound bases. The model is applied to the valuation and selection of 10 undeveloped petroleum reserves, giving the following outputs: a) estimation of the current value of petroleum reserve; b) estimation of the critical project value to invest immediately; c) estimation of the strategic value of the investment option; d) estimation of the optimallevel of working interest in each project. In order to make easier the application of the model, a software named INVESTPETRO was developed as part of this research. This work shows that the results of the traditional approach are distinct of those of the proposed model, especially when the leveI of uncertainties is high
