Analysis and National Solution for CO2 Gas in Missan Oil Field

Abstract

A site study on associated gas from six oil fields of the Missan Oil Company (MOC) was carried out during 2018. The studied zone is located in the southern part of Iraq. The main objective in the present work was to conduct a complete analysis of the associated gas from the oil fields of the MOC. Another objective was to propose theoretically an appropriate method of capturing carbon dioxide to make the natural gas compliant with the U.S. specifications for the pipeline of natural gas transportation. Gas quantities were measured from each oil field as well as component analysis to determine the percentage of carbon dioxide in the gas. The study revealed that CO2 concentration in the oil fields was slightly increased with time. Moreover, the results showed that the separation technique of CO2 from natural gas was the absorption method in the field of AMARA, while the membrane-separation method was preferred in Al NOOR field as well as BUS2 station, while the two methods are competing in the BAZRGAN field (BUS1, BUS3 and BUN stations).
