Erdal Yildirim: Method of in situ bitumen recovery by percolation. Cities Service Company, George L Rushton, September 27, 1983: US04406499 (27 worldwide citation)

Bitumen is recovered from an underground tar sands (oil sands) formation by an in-situ percolation process. After drilling a borehole to the bottom of the tar sand formation, the hole is enlarged by radially hydraulic jetting, with the resultant slurry being removed to the surface. Then, the main bo ...
