Immiscible displacement of trapped oil through experimental and data mining techniques.
… potential and competitiveness of gases used in immiscible gas-enhanced oil recovery (EOR) processes. Methane (CH4), Nitrogen (N2), Air (21%O2/N2) and Carbon Dioxide (CO2) are some of the gases injected in reservoirs to displace trapped oil from reservoir pores. The EOR screening process has been …

Lattice-Boltzmann modeling of multiphase flow through rough heterogeneously wet fractures
… roughness and heterogeneous wettability in immiscible displacement through single fractures. Since analytical solutions are restricted to simple domains and obtaining data from laboratory experiments is unpractical, a 3D direct simulation approach via the lattice Boltzmann method was …

Cold heavy oil production using CO2-EOR technique.
… - Based on conditions investigated, miscible displacement was found to be more efficient for deepwater production. However, immiscible displacement can offer greater reliability with regards to CO2 sequestration. 3. CO2 sequestration during CHOP using CO2-EOR technique – Lower CO2 may be …

Immiscible liquid-liquid displacement in microfluidic channels : effects of wettability and geometry
Displacement of a fluid by an immiscible fluid occurs in various situations such as oil recovery in underground reservoirs, transport in the human body, and other interconnected network systems and porous media. We are motivated by oil recovery processes in geological porous media that take place …

Numerical reservoir characterization using dimensionless scale numbers with application in upscaling
… is demonstrated for breakthrough time in an immiscible displacement in three dimensions. Numerical simulations were designed in dimensionless space and converted to dimensional space using several approaches. The resulting estimates of stability limits, numerical dispersion, and regime …

Rheology and Flow Behaviour of Non-Newtonian, Polymeric Fluids in Capillaric and Porous Media: Aspects Related to Polymer Flooding for Enchanced Recovery of Heavy Oil
… through the concept of Resistance Factor, Fr; 3) immiscible displacement of heavy oil by water and polymers to determine microscopic displacement efficiency; 4) larger-scale, 3D physical modeling of the polymer flood process; and, lastly 5) numerical simulation. A specialized rheometer was used to …

Phase Behaviour and Mass Transfer of Solvent(s)-CO2-Heavy Oil Systems Under Reservoir Conditions
… heavy oil resources worldwide through an immiscible displacement process. One major disadvantage of CO2 immiscible process is the limited solubility of CO2 in heavy oil, resulting in limited enhanced oil recovery. Addition of light alkane solvents to CO2 stream may provide a better …
