... asphaltene precipitation resulting in non-representative samples. Asphaltene Prescreening The de Boer Plot. The de Boer plot is a method to screen crude oils for their tendency to precipitate asphaltenes. It essentially evaluates the loss of asphaltene solubility as a reservoir-fluid sample is depressurized...
