Abstract
The present invention includes a method to determine if asphaltenes are soluble or insoluble in a solution. The solution may be a petroleum oil, a mixture of petroleum oils, petroleum derived oils and mixtures or similar combinations in a solvent. The invention includes the steps of illuminating the solution with a laser, measuring the small angle scattered light as a function of angle away from the laser beam, and determining if the asphaltenes are soluble or insoluble in the solution.
