We propose a flexible framework for evaluating prospect dependencies in oil and gas exploration and for solving decision-making problems in this context. The model uses a Bayesian network (BN) for encoding the dependencies in a geologic system at source, reservoir, and trap levels. We discuss different evaluation criteria that allow us to formulate specific decision problems and solve these within the BN framework. The BN model offers a realistic graphic model for capturing the underlying causal geologic process and allows fast statistical computations of marginal and conditional probabilities. We illustrate the use of our BN model by considering two situations. In the first situation, we wish to gain information about an area where hydrocarbons have been discovered, and use the value of perfect information to determine which locations are the best to drill. In the second situation, we consider the problem of abandoning an area when only dry wells are drilled. For this latter, we use an abandoned revenue criterion to determine the drilling locations. The application is from the North Sea. Our main focus is the description, visualization, and interpretation of the results for relating the statistical modeling to the local understanding of the geology. 8 AAPG Bulletin 95 ARTICULO Martinelli, Gabriele 51587 Eidsvik, Jo 51588 Hauge, Ragnar 51589 185591 185591 0 0 0 0 253410 BAAB BAAB 2026-03-06 200057680 0 200057680 2026-03-06 00:10:54 2026-03-06 ARTICULO
