This study puts forward the implementation of Multi-Criteria Decision Aid, through the PROMÉTHÉE V method, to support a decision on prioritizing a modification project portfolio on offshore oil and gas platforms. The chosen method supports, in a structured manner, the prioritization of a project portfolio which is necessary to leverage the oil production in offshore facilities, especially when they have already surpassed the plateau phase and presents production decline. Although the most relevant issues for investors are related to return on investments and the risks involved, the study suggests that other criteria are considered in specific settings. The research used data from 12 main projects of an oil and gas company and the criteria evaluations were made based on documents retrieved from the organization's database. This implementation represents a very important improvement for a well-known problem, in which the result is found based on criteria and their respective weights selected through a consensus. The results reinforce that any organization, with a constraint similar to the one presented in this study, may obtain relevant gains with the use of methods that clearly reflect the decision process and its criteria, assisting the decision maker's job significantly.
