The accessible ore of oil sands is located 50 to 200 m from the surface. Due to the difference in depth, recovery of oil sands ore calls for different techniques: open pit mining for shallow resources and steam assisted gravity drainage (SAGD) for deeper resources. These two oil sands processes techniques are described in more detail below.

Erosion occurs largely from direct sand removal from beaches, mostly through illegal sand mining. It can also occur indirectly, as a result of near-shore marine dredging of aggregates, or as a result of sand mining in rivers (Kondolf, 1997). Damming and mining have reduced sediment delivery from rivers to many

Oil sands process and production. Oil sand is a mixture of bitumen, sand, clay and water. Because it does not flow like conventional crude oil which is a liquid, it must be mined or heated underground before it can be processed. Once the bitumen has been extracted, we upgrade it into higher-value synthetic crude oil, diesel fuel and other products.
