One of the most important tasks for the production of an oilfield is to select well configurations that bring the best financial results and safety levels appropriate for the project development. However, the economy and safety must be observed in a horizon that corresponds to the whole life cycle of the well. The cost to build an oil well is directly related to the construction time, since most of its cost is linked to the daily values of the drilling rig. Well engineering has made great technological advancements in recent years in the development of new technologies and new well designs that will reduce the well construction time and thus the cost of the well. However, the question arises whether bolder designs are economical when considering the all life of the well, including Capex and Opex. The objective of this paper is to analyze the reliability and maintainability of four well configurations over their lifetime using a Reliability Block Diagram (RBD) and Monte Carlo simulation. This simulation was used to assess the demand for workovers over 27 years of production. Thus, it is expected to combine the costs of construction and maintenance of wells to assess which of the four projects has the best economic advantage.
