ABSTRACT
Steel pipelines and process equipment used in oil fields are subject to corrosion-erosion effects.Assessing and reducing these degenerative processes have important implications for oil fieldsafety and productivity. This paper presents the results of an investigation of the corrosion rates inthe oil well flow lines of an oilfield in the North African desert and factors that inhibit corrosion. Thepaper presents data gathered from corrosion coupons and ultrasonic measurements over a threeyearperiod (1994-1996) to show that the corrosion rates are significantly influenced by variablessuch as total production, water cut, and the volume of associated gas. This is followed by adiscussion of the factors that inhibit corrosion. The paper concludes with recommendations for theminimization of corrosion.
