BS&W stands for which phrase?

• A. Bottom Sediment and Water
• B. Bottom Solids and Wetness
• C. Base Sediment and Water
• D. Bottom Sediment and Wax

Answer: (A)

BS&W refers to the impurities that settle out of crude oil as solids and water. The term describes what collects at the bottom of a tank or in produced fluids: sediment (the solid particles) and water (the liquid phase). This exact wording—Bottom Sediment and Water—is the standard phrase used in production and refining to indicate quality issues and contamination that can affect processing. The other phrases don’t align with how this term is used in practice. They either replace “bottom” with something else, swap “sediment” for a different word, or add components like wax that aren’t part of the established definition.
