The majority of the growth would likely occur in the in-situ category, as in-situ projects usually have better economics than mining projects. Also, 80% of Canada's oil sands reserves are well-suited to in-situ extraction, versus 20% for mining methods.
The Athabasca oil sands, ... the net water requirement to produce a cubic metre of oil with in situ production may be as little as 0.2 m 3 [7.1 cu ft], ...
In 1980, a plant in Cold Lake was one of just two oil sands plants under construction in Alberta. [4] Although not developed as quickly and extensively as originally envisioned, an Imperial Oil plant in Cold Lake became the largest in situ oil sands project constructed in Alberta during the 1980s. By 1991, its daily oil production was 90,000 ...
In situ refers to recovery techniques which apply heat or solvents to heavy crude oil or bitumen reservoirs beneath the Earth's crust. There are several varieties of in situ techniques, but the ones which work best in the oil sands use heat (steam).
"Roughly 35 per cent of all in situ production in the Alberta oil sands uses a technique called high pressure cyclic steam stimulation (HPCSS), which cycles between two phases: first, steam is injected into an underground oil sands deposit to fracture and heat the formation to soften the bitumen just like CSS does, excepting at even higher ...
Whereas the Athabasca oil sands lie close enough to the surface that the sand can be scooped up in open-pit mines, and brought to a central location for processing, the Peace River deposits are considered too deep, and are exploited in situ using steam-assisted gravity drainage (SAGD) and Cold Heavy Oil Production with Sand (CHOPS).
In the oil sands, this thick, black gunk is mixed with sand and many chemical impurities such as sulfur; these must be separated from the bitumen for the oil to be useful. This can be done by surface mining and processing and by underground in situ techniques. Oil sands deposits in Alberta, Canada.
The Long Lake oil sands upgrader project is an in situ oil extraction project near Anzac, Alberta, 40 km (25 mi) southeast of Fort McMurray in the Athabasca oil sands region of Alberta. The project is owned and operated by CNOOC Petroleum North America, formerly known as Nexen. [1]
