The
Government of Alberta's commitment to research has contributed
to some significant technological developments in the energy
sector in the last 20 years. AERI is currently creating a
success stories inventory, but in the mean time, here are
just a few examples of "home-grown" technology that
has made a real difference in Alberta and throughout the world.
Working
Together for Tailings Excellence
The 2001
Thickened Tailings Field Trial (Paste Technology) is a great government-industry
collaborative success story. This tailings management improvement
initiative was undertaken to advance the oil sands industry commitment
to, and focus on, tailings management excellence.
SAGD
allows bitumen to be recovered from oil sands deposits that are impractical
for surface mining and extraction methods, but are not deep enough
for high-pressure steam techniques to work.
This
technology features a dry-retorting process for extracting bitumen
in surface mining operations. It involves moving oil sand through
a rotating drum, cracking the bitumen with heat to get lighter hydrocarbons.
This
technology separates bitumen from oil sands in surface-mining situations.
The process does not use caustic to improve the bitumen extraction,
and operates at ambient temperatures.
