Abstract: The development of petroleum production systems has become more and more sophisticated due to the complexity of deepwater oilfields, requiring cost effective and environment friendly systems. Petroleum companies generally employ methods of decision that consider the economic indicators solely, the net present value and the internal rate of return, among others. However, other non-economic aspects must also be analyzed during the evaluation of an E&P enterprise. The present work presents a model for decision-making that takes into account the main goals of a company, through the use of the theory of utility functions and multiple attributes. Besides introducing the mathematical theory behind the proposed model, this work illustrates its application via a current example: a deepwater field with a production potential of 100.000 barrels per day, where the facilities alternatives are a Semisubmersible Platform (SS), a Floating Production System and Offloading (FPSO) and a Tension Leg Platform (TLP). The case study was framed in terms of the technical risks of the project. The selection of the best option considered the financial risk, the environmental risk, the safety risk and the technological risk. The results suggest that the best alternative is not always the one exhibiting the best economic indicators.
