What parameter does a water cut test quantify?

• A. Oil density
• B. Water content in the cargo
• C. Temperature
• D. Gas content

Answer: (B)

Water cut test measures how much water is present in the cargo, expressed as a percentage of the total liquid volume. This is important because the amount of water in hydrocarbon cargo affects corrosion risk, microbial growth, stability of the product, and custody transfer accuracy. In practice, a sample is allowed to separate or is centrifuged to divide the water from the oil, and the water volume is divided by the total sample volume and multiplied by 100 to give the water cut. This directly assesses the water content, unlike oil density, temperature, or gas content, which are separate properties.
