Other in-situ strategies include toe to heel air injection (THAI), a comparatively new process that combines each vertical and horizontal air injections into underground wells, and a vapor extraction course of (VAPEX), similar to SAG-D – but with solvent injections as an alternative of steam. Here, the slurry is put through a separation process the place sand sinks to the underside and impure bitumen froth rises to the top.
