Comparison of the differential behaviour of production results under foam flooding with scaled M_ref,x relatively to constant M_ref,x as a function of the injection sequence (co-injection or alternate injection), V_DP = 0.22, 0.37, 0.57, K_ref,x = 100, 10 mD assigned to M_ref,x = 500 (or equivalently M_ref,x = 500, 1581 assigned to K_ref,x = 100 mD), K_z/K_x and L_z (subscripts “ani” and “iso” stand for K_z/K_x = 0.1 and 1 while “L_z” and “L_z/2” correspond to L_z = 10 and 5 m, respectively).
