I'm working on gas leakage in soil(porous media)
pressure leakage is 700psi,Porosity is 0.38 & permeability coefficient is about 3e-11 & 2e-12.
My question is that witch solver I should choose?
Pressure based or Density based?

It depends on the type of simulation you intend to perform. You use the pressure based for incompressible flow and density based for compressible flow.
