The objective of this Master s Project was to propose a methodology of evaluation of yet-to-find-oil, which utilizes stochastic methods and probabilistic analyses applied to the information available about basins with a long exploratory history, and which incorporates information about the area exhausted by previous exploratory efforts. The stochastic simulations were carried out by a full cycle, exploratory process modeling tool which is available commercially, and also at the Laboratory of Geological Correlation (LABCG) of the Geology Department at UERJ. A practical application of this composite methodology, using stochastic modeling and adjustment for area exhausted, was made in the play defined as the shallow waters of the Campos Basin. Utilizing only partial data about the discoveries of oil and gas fields, the results suggest that this area cannot yet be considered a mature exploratory play. Interesting perspectives for the discovery of additional total accumulations of oil and gas were also indicated, as well as individual accumulations of significant size. The application of the proposed methodology in basins with a reasonably extensive exploratory history, such as the Campos Basin in shallow waters, was shown to be perfectly viable. Another objective of this research was to help develop, within the Geology Department, a local knowledge center regarding the processes for evaluation of yet-to-find-oil, and about exploratory process modeling tools.
