The hydrodynamics of the capillary flow of a viscous-plastic liquid in cylindrical rectilinear pores is considered, as a result of which the structural velocity distribution over the pore cross section is obtained. Analytical solutions are proposed for the equations of hydraulic diffusion and nonlinear filtration for a non-Newtonian fluid in a cylindrical porous medium. It is noted that when a non-Newtonian fluid flows in a porous medium, the filtration equations take a nonlinear form due to the effective viscosity, shear, and yield stresses taken into account in its structure. The proposed solutions make it possible to evaluate the state of the porous medium and its main parameters (permeability, hydraulic diffusion, and effective viscosity coefficients). The obtained solutions are compared with existing experimental data for non-Newtonian oils.

“…In this model, asphaltenes are treated with solid colloidal particles surrounded by large resin molecules and suspended in crude oil. On the other hand, in the dissolution model, asphaltenes are dissolved in the solvent liquid state and form a uniform solution [15]. Among the many thermodynamic approaches used to predict asphaltene precipitation, regular solution theory along with the equation of state models are the most common methods [16,17].…”

The growing demand for oil is encouraging the development of heavy oil and bitumen, the world's huge energy reserves. However, their high viscosity is a big problem in their use, because they cannot be transported without a proper method. A number of methods have been developed to transport heavy oil, including diluents, heated pipelines, emulsions, and crude oil upgrades.It is known that the common characteristics of heavy oil are high viscosity, high specific gravity, high molecular content and low hydrogen-to-carbon ratio, high carbon residues, and high content of asphaltenes, heavy metals, sulfur, and nitrogen. Heavy oils are a strategic source of hydrocarbons because their reserves are on the same scale as those of conventional oils. The production of these raw materials remains low, especially due to their very high viscosities.Heavy oil rheology problems caused by the hydrodynamic interaction of heavy particles in oil (asphaltenes, paraffin, resins, and solid phase particles) were considered in the research work. Transporting heavy crude oil requires the viscosity to be low enough so that pipeline size and pumping requirements are economically optimal. There are several methods to achieve these properties, some of which have been validated in the field and are currently in use, while others are under development. In our current research work, we have analyzed some of these methods and given our recommendations for improving the rheology of heavy oils for the future.

“…Before further injection implementation in oilfield, characterizing in situ rheology in porous media is critical (Santoso et al 2017(Santoso et al , 2018(Santoso et al , 2020 and a series of influencing factors on flow characteristics of injection fluid should be considered, such as Non-Newtonian behavior in porous media, possible injection issues in the wellbore, sheardependent viscosity and retention-agglomeration process at pore-scale (Torrealba et al 2019;Zhang et al 2010). If the injected concentration or injection rate is too big, particles can buildup inside the pore throat, which can reduce the permeability of the reservoir (Santoso et al 2017).…”

Water well profile control is the main way to control water channeling in low-permeability fractured reservoirs, and preformed particle gels (PPGs) are commonly used. A preformed particle gel was prepared and the synthesis conditions were optimized. The temperature and salt resistant performance, plugging performance were investigated and the field application was tested. The results showed PPGs exhibited good temperature and salt resistant performance. PPGs with larger particle size showed greater plugging strength but shorter valid period. Field tests suggested that multiple rounds of profile control should be employed using PPGs with different particle sizes to achieve deep profile control.
