... during acid fracturing treatments. In addition, the non-uniform acid etching can be enhanced by the viscous fingering mechanism. For low-perm carbonate reservoirs, by multi-stage alternating injection of a low-viscosity acid and a high-viscosity polymer pad fluid during acid fracturing, the acid tends...

... and is unstable to transverse perturbations. These instabilities can grow, leading to fingering of the invading fluid. Numerical simulation of viscous fingering is challenging. The physics is controlled by a complex interplay of viscous and diffusive forces and it is necessary to ensure physical diffusion...

Paper Number: SPE-173290-MS
... Abstract Displacement of viscous oils often involves unstable immiscible flow. Viscous fingering and its influence on relative permeability was studied in this work at different viscosity ratios and flow rates. Silica and glass micromodels were used to visually inspect the effect of viscosity...

... while the right region consists of the low resolution mesh (1×1 m 2 grid blocks). In all these models the grid is orientated parallel to the main direction of flow. To investigate the importance of mesh orientation on viscous fingering, we also use a diagonal mesh arrangement using a grid size...

... Abstract This paper describes how an empirical model of compositional viscous fingering can be implemented in a conventional compositional reservoir simulator without major changes to the code. The empirical model is used to calculate pseudo relative permeabilities, transport coefficients (‘α...

... transition Introduction Viscous fingering has long been recognized as a factor in miscible gas injection processes, and attempts to describe mathematically the instability that triggers fingering and the subsequent growth of fingers have been the subject of much research over the last three decades...

In these simulations, the mixing parameter was set equal to unity to model complete mixing, i.e., no viscous fingering. Fingering probably...
