Claim 18:
19. A method according to claim 18, wherein:
the processing of iv) further involves inversion of the distribution of transverse relaxation values for each given capillary pressure values written in matrix form as

D=KD·F, 

where D is a two-dimensional matrix whose rows correspond to the different transverse relaxation values and whose columns correspond to different applied experimental pressure values,
F is a two-dimensional matrix whose rows correspond to different transverse relaxation values and whose columns corresponds to different capillary pressure values, and
KD is a two-dimensional kernel matrix defined as

KD,ij=Sw(Pcent,i,Pc,j)

where Sw(Pcent,i,Pc,j) is a step function or modified step function representing saturation of the pore sample as a function of applied experimental pressure.
