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 zonal isolation types uncertainty node configured to receive one or more zonal isolation types from the one or more inputs; a reliability level uncertainty node configured to receive one or more reliability levels from the one or more inputs; a cost level uncertainty node configured to receive one or more cost levels from the one or more inputs; a productivity level uncertainty node configured to receive one or more productivity levels from the one or more inputs; and a completion type decision node configured to receive one or more completion types from the one or more inputs; a junction classification decision node configured to receive one or more junction classifications from the one or more inputs; and a completion consequences node dependent on the zonal isolation types uncertainty node, the reliability level uncertainty node, the cost level uncertainty node, the productivity level uncertainty node, the completion type decision node, and the junction classifications 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 zonal isolation types, the one or more reliability levels, the one or more cost levels, the one or more productivity levels, the one or more completion types, and the one or more junction classifications.
