Paper Title
Study of Shear, Temperature and Pressure Effects on Viscosity and Viscoelastic Properties of Waxy Crude

in this study, Rheological properties of Heavy crude oil from mature fields of Mehsana is premeditated. Shear, temperature and pressure effects on viscosity and properties like gelation phenomena, crossover amplitude, and crossover frequency are studied profoundly by carrying out constant shear, frequency sweep, strain sweep and temperature sweep experiments on High pressure Anton Paar Rheometer. The interpretation of rheological behavior was related with crystal growth. Key words- waxy crude oil, gelation, storage and loss modulus, crossover point, oscillatory shear, linear viscoelastic range.
