METHODS OF IMPROVING RHEOLOGICAL PROPERTIES OF CRUDE OILS

Methods of improving pheological properties of crude oils to reduce the viscosity may involve beat treatment or the addition of a surface active agent. After an oil is heated above a certain temperature, the asphalt is activated and adsorbed on active surfaces of precipitating paraffin, thereby inhibiting additional wax deposition. In a series of experiments, Permian crude oils were heated in a sealed container to 50 C, then cooled at the rate of 1 C/min. In one case, such treatment reduced the viscosity more than five fold, from 40.7 cs at 5 C to 7.75 cs. Similar results were obtained with many crude oils. It was also found that crude oil viscosity can be lowered 12% by addition of 0.25% of surface active agent (alkylphenolate).
