Definition of reservoir characteristics, such as porosity, permeability, and fluid-content, on the scale of meters, is the key to planning and control of successful enhanced oil recovery operations. Equations relating seismic and electrical properties to pore topology and mineral-fluid interactions are needed to invert geophysical images for reservoir management. Both the geophysical and transport properties of reservoir rocks are determined by pore topology and the physics and chemistry of mineral-fluid and fluid-fluid interactions. The objective of this research is to understand, using analysis and experiment, how fluids in pores affect the geophysical and transport properties of reservoir rocks. During the October-December 1992 quarter, research was carried out in the following areas: formation factor and the distribution of a wetting phase in the pore space of Berea sandstone, numerical simulations of fluid flow in porous rock using graph theory. A comprehensive report entitled ``Measurements and Analysis of Seismic Properties`` on the seismic measurements and their analysis was completed.
