... without polymer, suggesting a synergistic effect between HAPAM-2 and DDG which further reduced IFT. However, the IFT of DDG solution was not affected in the presence of HAPAM-1. Micromodel experiments indicated that the oil production efficiency by initial HSW injection was quite low, then displacement...

...-to-water ratio of 7:3. Micromodel test indicated that the residual oil blocks were effectively replaced by the VR flooding due to the strong emulsification and increased sweep efficiency by heavy oil viscosity reduction. The injection pressure decreased by the VR flooding due to a reduced viscosity...

... characterized by compatibility test, interfacial tension (IFT) test, emulsification test, and phase behavior test. The potential for increasing oil production was evaluated by micromodel displacement tests. The micromodel was treated to oil-wet to simulate the wettability of carbonates. The performances...

... and demonstrate that it renders the high resolution, 3D confocal images of pore casts. In our work, we use silicon micromodels as a reference to validate the key parameters of high-pressure resin impregnation. We demonstrate possible artifacts and defects that might develop during rock impregnation with resin...

... experiments were conducted and recovery mechanisms in carbonate and sandstone-like pore structures were visualized using micromodels. The objective of these experiments was to enhance our understanding of fluid flow and oil recovery mechanisms through utilization of surfactant solution as the main injectant...

... Abstract In this work micromodels are generated from high resolution images of unconsolidated sands and subsequently used to study polymer EOR processes. Using this approach an almost unlimited number of equal copies can be produced. Moreover, compared to cores, the micromodels enable visual...

... Abstract Two series of flow visualization experiments were carried out to examine the behaviour of immiscible gas injection and water flooding in two-dimensional porous micromodels with fractures at various orientations. One main objective of the study was to test the validity of several...

The fractures were either parallel to the macroscopic flow or perpendicular to it. Extensive experiments on two-phase flow...
