A method is disclosed for modeling a reservoir, comprising: receiving a
set of wettability logs from a wettability logging tool adapted to be
disposed in a wellbore; generating a wettability map in response to the
wettability logs; generating a gridded simulation model, the gridded
simulation model including a plurality of grid cells; determining, for
each grid cell of the gridded simulation model, a local value of
wettability from the wettability map; determining, for each grid cell of
the gridded simulation model, a permeability model and a capillary
pressure model from the local value of wettability associated with each
grid cell; and generating a set of simulation results representing
characteristics of the reservoir.
