MEG Energy uses steam-assisted gravity drainage, or SAGD, technology to recover bitumen.
The top well injects steam to heat the bitumen, which separates from the sand and collects with the produced water in the lower well, approximately five metres below. The bitumen is then pumped to the surface, where it is separated from the water. The water is treated and recycled into the system.
The steam-oil ratio, or SOR, is an indicator of the efficiency of a SAGD operation. Generally, an SOR of less than 3 is considered to be an efficient operation. MEG achieved an SOR of 2.4 in 2021 at its Christina Lake project. The eMSAGP process has been shown to significantly reduce the overall steam-oil ratio relative to SAGD. Lower SORs equate to improved efficiencies and cost per barrel of bitumen produced.
Additional requirements are found from deep water sources that are not suitable for consumption or agricultural uses. No surface water is used in the process.
More than 80% of Canada’s oil sands can only be accessed by drilling technologies, like SAGD.
With horizontal wells stretching more than a kilometre beneath the surface, a large area can be developed with minimal impact to the land. SAGD operations typically disturb only 10% to 15% of the surface of the development area.
SAGD allows development in stages, helping to manage costs and workforce peaks. MEG's current operations and future plans are based on multi-stage brownfield expansions.
While SAGD is a proven technology, it is still relatively young and holds the potential for improved recovery rates, greater energy efficiency and lower costs as we continue to research and test potential enhancements.
