Extraction
There is more than one way to extract oil sands from the ground. Mining techniques are used where the oil sands are close to the surface and in-situ techniques are used for deeper deposits. In mining operations, oil sands ore is dug out of the ground and processed to separate the bitumen from the sand. When an area is mined out, the earth is put back and reclaimed to productive use. In-situ techniques are used underground to liquefy bitumen flow to a point where it can be pumped by a well to the surface, leaving the sand in place. In-situ is Latin for “in place.” Both methods of extraction present benefits and challenges in terms of production rates, surface land disturbance, energy use, time and investment required for each type of project.
