Tham Summary A 3D, three-phase (oil/water/gas) permeability modification simulator was developed by incorporating an in-situ gelation model into a black-oil simulator (BOAST). Several important features that describe gel-system transport...

In frontal-advance models, the reservoir is assumed to be horizontal and the steam front and saturation and temperature isosurfaces are assumed to be vertical. The earliest such model that gained wide acceptance was that of Marx...
