Water usage is another critical concern, as the process requires large quantities, sourced primarily from the Athabasca River. Pairs of horizontal wells are drilled underground, and high-pressure steam is injected to heat the bitumen, reducing its viscosity.
Alberta Oil Mining Future Direction Trends: In-Situ Extraction and Environmental Evolution
Two primary extraction methods exist, dictated by the depth of the deposit. The extraction process is energy-intensive, leading to higher greenhouse gas emissions per barrel compared to conventional oil.
This technique avoids the massive mining pits but requires significant energy input. The process requires the removal of substantial overburden, which is stored in adjacent areas known as tailings ponds.
Alberta Oil Mining Future Direction Trends and Emerging Technologies
Advances in recycling water, reducing emissions, and improving energy efficiency are central to the industry's efforts to mitigate its environmental impact and transition toward a lower-carbon future. In-situ drilling is used for deeper resources, involving the injection of steam or solvents to liquefy the bitumen so it can be pumped to the surface.
