Abstract
In oil production companies, corrosion is a common issue with various adverse economic and environmental consequences. Active well production fluid always comprises inherently corrosive and highly corrosive substances. There are a variety of treatment techniques to prohibit corrosion, such as chemical treatment, cathodic protection, and paint-based corrosion inhibitors. El Hamra Oil Company produces crude oil from three main locations. The research group noticed several downhole localized corrosion problems in the artificial lift system. This paper presents a case study to quantify the extra operation cost of periodically replacing the entire tubing string, renting the pulling unit, and production deferring. The research quantifies the economic impacts after corrosion inhibitor is injected downhole using the carrier line technique (CLT). The results show that the company saved more than 672 K $ during three years of using downhole chemical treatment; dramatically decreasing the regular corrosion incidents in three active wells. The actual profits are expected to increase exponentially for the following years, meanwhile reducing the environmental impacts to meet Egypt’s strategy towards sustainable goals in 2030.
期刊介绍:
Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
