Abstract
A method and apparatus for the measurement and prediction of waxy crude characteristics is disclosed. The method is for treating oil samples having at least some wax, by the steps of isolating a sample of crude to be tested, testing the sample by subjecting the sample to known amounts of at least one of pressure, shear rate and temperature, and evaluating the wax in the tested sample. In another embodiment the apparatus includes at least one of a pressure chamber to hold an oil sample, a pressure control to control pressure of the sample, a temperature control to control the oil temperature, a shear rate control to control shear rates in the sample and a sensor and data acquisition system to measure particle characteristics of said sample, to simulate field conditions which waxy crudes may be subjected to.
