“…Oil is someti destillation fo applied which gases and var simplest way summary of e viscosity of he follow power law for their shear modulus (Hinkle, 2008). Though done only on few set of samples, the idea has been brought for not to only focusing on the asphaltene but also to the other heavy-molecular weight resins.…”

“…Figure 3. Arrhenius type viscosity and Shear modulus vs the content of Asphaltene+Resin (Hinkle, 2008) With many more data, Evdokimov made a breakthrough by explaining the inconsistent hyphotesis of viscosity of dead crude oil as a function of asphaltene's content as in Figure 4. This inconsistency is mentioned as multi-peak correlation which is explained as the cause due to phase boundaries of asphaltene nanocolloids.…”

Oil production is highly depend on its viscosity which varies with temperature and pressure. Chemically, the viscosity had tight relationship with asphaltene content. The higher the asphaltene content as in the heavy oil, the higher the viscosity is and the more difficult to be produced. A brief review of Saturates, Aromatics, Resins and Asphaltenes (SARA) fractions of oil and how they are extracted and analysed followed by how asphaltene related with viscosity then its theoretical models and its precipitation mechanism, is given. The paper then expose the viscosity vs temperature behavior of Indonesian heavy oil and relates with its SARA measurement.

“…Figure 1(a) shows that the Heavy oil sand measurement shear viscosity gradually decreases with the increment of temperature. Usually, shear viscosity varies by orders of magnitude even at the same API gravity depending on the chemical composition of heavy oils (Hinkle et al, 2008). The high shear viscosity at low temperature enables heavy oils to act as part of solid frame, especially when the temperature is less than glass point.…”

The elastic properties of heavy oil sands are influenced by multiphase of heavy oil and sands grain, as well as temperature, pressure, microstructure and sedimentary history. In order to quantitatively investigate the role of a single phase in integrated rock of heavy oil sands at a specific condition, special laboratory measurements on oil and sands of heavy oil sands rock are designed and performed for three artificial samples. By the improved laboratory approaches, we can gain an insight into the physical interaction between the solid and fluid components in heavy oil sands. The exact laboratory results reveal that the elastic properties of heavy oil is distinctively temperature dependent, which reflects the total variation of the multiphase on temperature, and in turn demonstrates that heavy oils dominate the elastic properties of the heavy oil sands. Furthermore, the extended Gassmann model indicates that heavy oil properties may be the major reason for the misfit of underestimating the both P-and S-wave velocities as temperature decreases.

“…Heavy crude oils, with an API gravity less than 20 (Hascakir et al 2009), have been found in different regions in the world, such as the Orinoco Belt in Venezuela, Alberta in Canada, some regions of the Gulf of Mexico, and northeastern China (Galarraga et al 2007;Rana et al 2007;Hinkle et al 2008;Chen et al 2009;Martínez-Palou 2011). However, the compositional complexity and poor flow properties of heavy crude oils bring out many problems and challenges in oil production, transportation, and refining (Saniere et al 2004).…”

The low-temperature catalytic oxidation of heavy crude oil (Xinjiang Oilfield, China) was studied using three types of catalysts including oil-soluble, watersoluble, and dispersed catalysts. According to primary screening, oil-soluble catalysts, copper naphthenate and manganese naphthenate, are more attractive, and were selected to further investigate their catalytic performance in in situ upgrading of heavy oil. The heavy oil compositions and molecular structures were characterized by column chromatography, elemental analysis, and Fourier transform infrared spectrometry before and after reaction. An Arrhenius kinetics model was introduced to calculate the rheological activation energy of heavy oil from the viscosity-temperature characteristics. Results show that the two oil-soluble catalysts can crack part of heavy components into light components, decrease the heteroatom content, and achieve the transition of reaction mode from oxygen addition to bond scission. The calculated rheological activation energy of heavy oil from the fitted Arrhenius model is consistent with physical properties of heavy oil (oil viscosity and contents of heavy fractions). It is found that the temperature, oil composition, and internal molecular structures are the main factors affecting its flow ability. Oil-soluble catalyst-assisted air injection or air huff-n-puff injection is a promising in situ catalytic upgrading method for improving heavy oil recovery.
