Hopefully the link works (sorry computer dummy here) if not most of what I am seeing lately is the Europump in the Wabasca fields. Euromax to be specific. Tiny footprint compared to a pit operation & respectable production numbers as well as a decent maximum depth recovery. To be clear this is fairly old tech that has been under constant refinement. This latest gen approaches it from the perspective of lets stop throwing massive horsepower at it & consider how the material wants to move then build pumps that do that. Essentially it takes advantage of the surface tension of the material to move the material. That's why you see so many variations on the pump (corkscrew) when the material changes just get a different corkscrew & continue pumping. IIRC the max depth is +/- 6000 ft.
