Apparatus and methods are disclosed for recovering hydrocarbonaceous and additional products from oil/tar sands. The method includes the steps of forming a hole in a body of oil or tar sand, positioning an apertured sleeve within the hole to minimize fill-in of the sand, positioning a gas inlet conduit into the apertured sleeve, and introducing a heated, pressurized processing gas into the sleeve through the gas inlet conduit, such that the heated, pressurized processing gas penetrates into the sand through the apertures, thereby converting bitumen within the sand into hydrocarbonaceous products. The processing gas and hydrocarbonaceous products are withdrawn as effluent gas through the hole under relative negative pressure. The apertured sleeve may be installed in sections into the hole as the hole is formed. The apertures in the sleeve may be holes with a circular or other geometry or elongate cuts. In particular, the apertures in the sleeve are elongate cuts oriented more vertically than horizontally; that is, more aligned with the axis of the sleeve. A mesh screen may be supported between the apertured sleeve and the body of oil or tar sand.
