“Sour service” refers to a term used in the oil and gas industry to describe the conditions of a pipeline or well environment that contains hydrogen sulfide (H2S), a toxic and corrosive gas. Sour service can also refer to other corrosive environments that contain high levels of sulfur compounds. These conditions can pose a significant risk to the integrity of pipelines and equipment and can lead to corrosion, cracking, and other forms of degradation. To address the challenges posed by sour service, specialized materials and coatings are used in the construction of pipelines and equipment, and specialized procedures and practices are employed in the drilling, production, and transportation of sour oil and gas.
