Rock, Pore Space, and Fluid Systems
The principles and concepts concerning fluid behavior discussed in earlier chapters have centered on the hydrologic component of the subsurface environment in terms of single bodies of homogeneous fluid. It is not really this way in a rock, however, since any single fluid mass is essentially interspersed within a network of intergranular pore spaces, throats, fracture openings, etc. As long as the fluids are in complete communication, the principles are valid, but to understand pressure and flow relationships the effects of the mineral grain matrix must be considered as well.
