Claim One:
1. A system, comprising: one or more processors; a non-transitory tangible computer-readable memory, the memory comprising: a well completion expert system executable by the one or more processors and configured to provide one or more well completion recommendations based on one or more inputs, the well completion expert system comprising a well completion Bayesian decision network (BDN) model, the well completion BDN model comprising: a fluid loss formation uncertainty node configured to receive one or more fluid loss formations from the one or more inputs; an open hole gravel pack type uncertainty node dependent on the fluid loss formation uncertainty node and configured to receive one or more open hole gravel pack types from the one or more inputs; a gravel pack design details uncertainty node configured to receive one or more gravel pack design details from the one or more inputs; an open hole gravel pack decision node uncertainty node configured to receive one or more open hole gravel packs from the one or more inputs; a completion type decision node configured to receive one or more completion types from the one or more inputs; and an open hole gravel pack consequences node dependent on the open hole gravel pack type uncertainty node, the gravel pack design details uncertainty node, the open gravel pack decision node, and the completion type decision node and configured to output one or more well completion recommendations based on one or more Bayesian probabilities calculated from the one or more open hole gravel pack types, the one or more gravel pack design details, the one or more open hole gravel packs, and the one or more completion types.
