In Situ Methods used in the Oil Sands In situ methods are used to recover bitumen that lies too deep beneath the surface for mining (about 80% of the oil sands in Alberta). The success of in situ methods depends on the resolution of two major issues 1) reducing the viscosity of bitumen so that it will flow, and 2) recovering the bitumen from deep within the earth (OSDC 2008c).
