Note: The "flow rate" column applies to leaking wells, pipelines, etc., and is often used to estimate the total amount of oil spilled. The "full cargo" column applies to vessels, vehicles, etc., and represents the maximum amount of oil that could be spilled. The "spilled" columns indicate the total amount of oil that has been released to the environment so far, and should be based on official estimates found in referenced sources whenever possible. When official estimates vary, use the "min" and "max" columns to show the range of estimates.

Note: The "flow rate" column applies to leaking wells, pipelines, etc., and is often used to estimate the total amount of oil spilled. The "full cargo" column applies to vessels, vehicles, etc., and represents the maximum amount of oil that could be spilled. The "spilled" columns indicate the total amount of oil that has been released to the environment so far, and should be based on official estimates found in referenced sources whenever possible. When official estimates vary, use the "min" and "max" columns to show the range of estimates.
