On the Linear Stability Problem for a Three-Layer Displacement in a Porous Media

G Pasa - International Journal of Petroleum Technology, 2022 - avantipublisher.com
In this paper, we study the secondary oil recovery process. The oil from a porous reservoir at
low pressure is pushed by a forerunner, less viscous fluid (a polymer solute). Then the well …
