In many practical cases the pore compressibility can be considered as independent on reservoir pressure variation: c_r(p) = c_r = \rm const.
But in case the reservoir pressure is changing substantially one may need to account for the effect it takes on pore compressibility.
The model is usually relates pore compressibility c_r(p) to a given pressure p and initial pore compressibility c_{ri} at initial formation pressure p_i.
