Abstract
Viscous asphaltenic crude oils are converted to pumpable liquid oil products in field locations by precipitating and separating asphaltenes, then mildly thermally converting the asphaltenes to mobile asphaltene-conversion products that can be mixed with at least the maltene components of the crude oils to form the pumpable liquid oil products.
