DIP–MS is a fast and easy tool that can identify classes of compounds in opportunity crudes (heavy and ultraheavy crude oils, asphaltenes, and tar sands) in the field, without prior separation or treatment. It may enable fast screening of real samples to make a rough evaluation of the potential of reservoirs and oil fields.
