reliability level, cost level, productivity level, the completion type, and the junction classification decision nodes Expert system for well completion using bayesian probabilities and a consequences node dependent on the zonal isolation types

Systems and methods are provided for expert systems for well completion using Bayesian decision networks to determine well completion recommendations. The well completion expert system includes a well completion Bayesian decision network (BDN) model that receives inputs and outputs recommendations based on Bayesian probability determinations. The well completion BDN model includes a treatment fluids section, a packer section, a junction classification section, a perforation section, a lateral completion section, and an open hole gravel packing section.
