Model X-ray scattering behaviour of arrays of structured cylinders.
… viz: the cylinder's scattering function, the swelling factor (Y), and the lattice interference function. The behaviour of the scattering function is considered as the cylinder's structure (electron density distribution) is systematically varied from the case of a solid cylinder to that of a …

Utilization of Carbonated Water Injection (CWI) as a Means of Improved Oil Recovery in Light Oil Systems: Pore-Scale Mechanisms and Recovery Evaluation
… In addition, the results obtained from swelling/extraction tests revealed that the oil swelling factor increases as the pressure rises until a certain pressure called extraction pressure, Pext is reached. Afterward, the swelling factor reduces due to substantial extraction of lighter …

Performance Evaluation of an Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs
… module. For the CH4-C3H8-heavy oil mixture, the swelling factor of heavy oil maintains at a relatively high value for each test temperature, while the measured saturation pressures are also found to have high values. The tuned Peng-Robinson equation of state (PR EOS) (1978) model can be used to …

Quantification of Phase Behaviour and Physical Properties of Solvents-Heavy Oil/Bitumen-Water Systems at High Pressures and Elevated Temperatures
… to optimize the reduced temperature for acentric factor for the Peng-Robinson equation of state (PR-EOS) and Soave-Redlich- Kwong equation of state (SRK-EOS) by minimizing the deviation between the measured and calculated vapour pressures. The reduced temperature has its optimum value of 0.59 for …

Phase Behaviour and Mass Transfer of Solvent(s)-CO2-Heavy Oil Systems Under Reservoir Conditions
… alpha function with the redefined acentric factor at a reduced temperature of 0.6 provides more accurate prediction of vapour pressures of nonhydrocarbon and hydrocarbon compounds, especially heavy hydrocarbons. Subsequently, the enhanced swelling effect and viscosity reduction of CO2-heavy …

An Experimental Study of Carbon Dioxide Dissolution into a Light Crude Oil
… CO2 solubilities in the light crude oil, oil-swelling factors, and CO2-saturated light crude oil densities at different equilibrium pressures and the actual reservoir temperature of Tres = 56.0°C. Second, the onset pressure of the initial quick light-hydrocarbons (HCs) extraction was …

Optimum Timing for CO2-EOR After Waterflooding and Soaking Effect on Miscible CO2 Flooding in a Tight Sandstone Formation,
… First, the saturation pressure (Psat), oil-swelling factor (SF), gas–oil ratio (GOR) of CO2- saturated light oil, and gas–water ratio (GWR) of CO2-saturated reservoir brine were measured by using a PVT system. Second, the viscosities of CO2-saturated light oil with different CO2 …

Mass transfer studies in heavy oil recovery using solvents
"Heavy oil, sometimes called bitumen, is known for its high viscosity (above 100 cp) and low API gravity (below 22⁰). In most cases, viscosity reduction is needed for the final product. There is a considerable amount of heavy oil in Alberta, Canada and the world's largest heavy oil deposit is in …
