Project Oilsand, also known as Project Oilsands, and originally known as Project Cauldron, was a 1958 proposal to exploit the Athabasca Oil Sands in Alberta via the underground detonation of up to 100 nuclear explosives;^[1] hypothetically, the heat and pressure created by an underground detonation would boil the bitumen deposits, reducing their viscosity to the point that standard oilfield techniques could be used.
