Light sweet crude oil is a valuable form of crude oil with low sulfur and wax content, making it easier to process and convert into high-demand fuels. Refineries prefer it, but shortages can cause a drop in fuel quality and higher prices for consumers.
Light sweet crude oil is a particularly sought-after form of crude oil that can be used to produce products such as high-quality gasoline, kerosene, and diesel. While many consumers think that most crude oil is essentially the same, there are actually a number of classifications for crude oil that are used to divide oil by impurities and consistency. Some forms of crude oil are considered more valuable than others, with sweet and light crude generally commanding the highest prices in the market.
Sweet crude is a form of crude oil that has a sulfur content of less than 0.5%. Typically, it also has lower levels of other impurities, and the name is a reference to the flavor; sweet raw has a slightly sweet taste, for those who want to give it a try. (Although it should be noted that actual ingestion of any oil is not recommended.) The lower levels of impurities make it easier to process, because the resulting products don’t have to be filtered as extensively. Conversely, it is also possible to find acidic crude oil, which has a higher sulfur content.
Light crude oil is crude oil that has a low percentage of wax. This means that the viscosity of the oil is much lower, making it easier to pump, transport and handle. Light crude is also less likely to clog processing systems. This is in contrast to heavy crude, which is thicker and generally of lower quality.
In the case of light sweet crude, the oil is both light, with a low wax content, and sweet, with a low sulfur content. It also tends to contain a higher percentage of fractions that can be converted into fuels in high demand. Because this oil has so many useful characteristics, it is often a highly desirable product, with many refineries preferring to work with it whenever possible. The hype about it puts heavy pressure on areas with large deposits of sweet and light crude oil, such as Alaska.
In times of oil shortage, refineries will work with other forms of crude, but this can cause a corresponding drop in fuel quality. Refineries may also charge a premium for their high-quality fuels, which reflects the difficulty they have in obtaining raw materials. This can directly affect consumers, many of whom use sweet and light crude oil products in their daily lives.
