Is the crude sour or wet service?

Crude oil can be classified as sour or sweet based on its sulfur content; sour crude contains higher levels of sulfur, while sweet crude has less. Wet service typically refers to environments where water is present, which can occur with both types of crude, especially during extraction and transportation. Therefore, crude oil can be either sour or sweet, and it can be involved in wet service conditions depending on the specifics of the operation.
