A dual2po ro sity model based on the modif ied fo rm u lat ion by Barrenb lat t is p resen ted fo r

and po ro sity coeff icien t s in the con t ro l equat ion s are regarded as con stan t in mo st s of literatu res. O f cou rse,
th is is no t t rue. The perm eab ility and po ro sity are actually varied w ith p ressu res in m at rix b lock s and
