ABSTRACT This paper contains the description of the process used for selecting a platform for petroleum exploration.

Starting from a given set of requirements, such as field location (Gulf of Mexico), depth, type of the well, and etc, a deep analysis of the environmental conditions, the infra structure of the place where the wells took place, and the existing options of systems were made in order to choose the three most suitable options for this situation.

Once the options were analyzed, a decision matrix was used to quantify the viability of each of the systems considered, making the decision process much more direct.

During the work, a number of references were consulted for theoretical reasons. these references are listed at the end of this report.
