Sulphide and carbon (IV) oxide corrosion in oil exploration and exploitation operations

Abstract

This is an attempt to determine the susceptibility of carbon IV oxide (CO2) and Hydrogen Sulphide (H2S) corrosion of three different materials, namely; Type (316) Austenite Stainless Steel, Mild Steel and Conventional drill-pipe in sour environment -(H2S/mud medium and CO2/mud medium). The weight loss method was used. Results of the experiment showed that mild steel material was the most susceptible material to corrosion in the environment while Type (316) Stainless Steel material exhibited the best performance of all the materials. The result of this study can be used in the design of crude/product flow lines in the refining and producing operations.
