Permeability is treated by using various methods to enhance the flow of fluids through a porous medium. One common method is hydraulic fracturing, which involves injecting high-pressure fluids into the reservoir to create fractures and increase permeability. Another approach is acidizing, where acid is pumped into the formation to dissolve minerals and open up pathways for fluid flow. Additionally, permeability can be improved through the use of chemical treatments or by injecting steam to heat the reservoir and reduce viscosity. **
