Development of a New Tool as a Qualitative Screening Criteria for EOR Methods

Abstract

Oil production from reservoirs undergo three stages. They are primary, secondary and tertiary stages. In the tertiary (EOR) stage, several methods and technologies are used to increase or uphold recovery from existing fields. These methods often involve the injection of fluid(s) and recently microbes into a reservoir. The variety in principle for EOR methods suggests the need for proper selection, design, and implementation technique. One of the most used method for quick screening is considering the successful previous experiences from the methods that have been applied in other fields. In this paper, an EOR screening tool, named "EOR Azzaytuna Analysis", has been designed using visual basic studio. The database of the tool is based on the updated screening criteria by Al Adasani and Bai which was published in 2010. The published data from some oil fields which have already applied the EOR methods, were acquired. The tool screened these fields and the obtained results were compared with the already given one to confirm the success of the development of "EOR Azzaytuna Analysis" as a screen tool.
