API Gravity

API Gravity is a measure used to assess the density of petroleum liquids compared to water. It is quantified using a scale where higher values indicate lighter oils, which are generally more valuable and easier to refine. Specifically, an API Gravity above 10 means the oil is lighter than water, while below 10 indicates it is heavier. This measurement helps in determining how oil will behave during extraction and refining processes, guiding producers and refiners in their operations and economic decisions.
