A method for recovery of oil from porous subsurface formations is described comprising: (a) mining a vertical shaft through said formation, (b) mining and drilling an upper, horizontal rectangular grid of drift and bore holes outward from said shaft, (c) mining and drilling a lower horizontal, rectangular grid of drift and bore holes outward from said shaft, (d) applying super heated, pressurized oil vapor through alternate bore holes of said lower grid to heat said formation, (e) simultaneously applying hot, pressurized flue gas through said upper grid to heat said formation and force oil downward, (f) condensing said super heated oil vapor in said formation and recovering heated flowable crude oil mixed with said condensed oil vapor through said lower grid, and (g) recycling a portion of said recovered crude oil as said super heated, pressurized oil vapor; wherein said upper and lower grids are oriented in a parallel relationship relative to the dip and strike of said subsurface formation with said drifts aligned with the dip and said bore holes extending perpendicularly to said drifts and aligned with the strike.
