This paper proposes a new criterion to estimate the impact of lean zones on thermal or
thermal-solvent processes, such as SAGD, SA-SAGD, or EBRT (Imperial Oil's" Enhanced
Bitumen Recovery Technology"). The interface stability of the steam/solvent chamber in the
lean zone is related to the competition of heat transfer in either conductive or convective
forms. This competition is described by a non-dimensional number, the Rayleigh number in
porous media, which can be calculated by the parameters of the lean zone thickness, water …
