This article intends to approach a method of identifying and calculating indicators for evaluating configurations of oil wells in ultra-deep waters; during the design phase, when the decision will take place, the proposed indicators may contribute to managerial decision-making. After the introduction, the article briefly presents the adopted methodology, the results obtained in the literature review, the suggested indicators and their calculation methods. Suggested indicators are: unreliability and availability of barries elements, downtime due to repairs, repair costs, probability of ceasing production or injection, and expected reduction in nominal flow due to degradation of production components. The conclusions are: a) that a robust and well-established methodology was adopted for the bibliographic review, b) unexpectedly, the subject indicators for oil well evaluation are little explored in the literature, c) that the process using several sources of information allowed the research to reach an interesting set of indicators, and d) these indicators must now be validated and tested.

Keywords: Oil well, Oil well indicators, Oil well design, Indicators quantification.
