ABSTRACT: One of the main concerns of each petroleum engineer is the selection of
the best EOR method to maximize the oil production from the reservoir. In this
regard, one of the explored-not-productive southern Iranian oil fields was
considered as the objective of this study to find which enhanced oil recovery
(EOR) method is the proper method to apply on this reservoir. Therefore, a
procedure capable of combining the data extracted from different sources
ranging from worldwide field experiences to the existing tables into a unified
expert system is used. This expert system is based on Bayesian network analysis
in order to sort the proper EOR techniques for further assessment by economical
and environmental criteria. In addition, after collecting of surface samples at
the gas and liquid separator, and subsequently recombined with solution gas oil
ratio, several tests including constant composition expansion (CCE) (flash
vaporization, flash liberation flash expansion, pressure-volume relations),
differential vaporization (differential liberation differential expansion) and
solubility and swelling tests were performed.
