This link provides an extensive bibliography of pertinent papers, plus a brief library of papers in Adobe Acrobat PDF format that are fundamental to the reservoir characterization models.  The papers are organized by subject matter.

1)  Pore Space Characterization
     These papers demonstrate the progressive learning of the presence, type and role of pore geometry in a reservoir.
     -Determining pore volume of a rock (core and log processes).
     -Documenting size, shape and distribution of pores (rooms) and pore throats (doors) using thin section, scanning electron microscope photos and
      capillary pressure curves (Pc).
     -Integrating pore geometry with fluid (oil, gas, water) distribution and performance.

2)  Reservoir Fluid Distribution
    
Fluid distribution and flow with pressure drop was not well understood until the 1940's, and these papers track that learning curve.  The paper by
     Illing (1939) provides a platform for linking fluid flow to changes in grain size (pore geometry) of various sand packs in horizontal tubes.  This document
     fueled the investigation into buoyancy (capillary pressure) and 2-phase relative permeability applications. Simultaneously, Archie researched and
     published a relationship that relates water saturation to porosity, resistivity and pore geometry.

3)  Reservoir Architecture
    
Vertical and lateral depositional fabric influences performance.  Diagenesis (alteration of primary pore space) also modifies performance in either
     positive or negative directions.
