... decision tree, built up through decision and chance nodes, to establish a distribution of recoverable volumes and rank the recovery strategies given a chosen criterion. A second uncertainty study is performed by adding economic uncertainties to the initial set of reservoir uncertain parameters. Eventually...

... performance. Furthermore, the two‐factor model combined with the modified LSM algorithm is tractable and provides useful insights into the IOR switch‐time problem. The novelties provided by this work are developing and illustrating the structure of the IOR switch‐time problem using a decision tree...

...S. I. Ozkaya Summary This paper describes the procedure of building a probabilistic decision tree on the basis of the integration of data from multiple sources, conditional probabilities, and the application to map fracture corridors (FCs) in a mature oil field with abundant production data. An FC...

... method to propose an approach to account for missing well logs during permeability predictions. This is a common problem encountered during field applications. Our approach follows directly from the hierarchical decision tree that visually and quantitatively illustrates the relationship between the data...
