Oil is extracted from porous reservoirs primarily through two methods: water flooding, where water is pumped below the reservoir to push oil to the surface, and bioremediation, which involves using bacteria to enhance oil recovery. Water flooding can recover about 40% of the oil trapped in the porous material. Magnetohydrodynamics plays a role in modeling the physical properties of fluids involved in oil extraction, such as permeability and conductivity. This field helps predict the behavior of oil and water mixtures, similar to how fluid dynamics informs air flow over airplane wings. Understanding these processes is crucial for optimizing oil extraction techniques.
