Abstract
Steam Assisted Gravity Drainage (SAGD) is a technique of
heavy oil recovery used on oil sands in Alberta, Canada. Steam
is injected down hole in the reservoir and the steam fluidizes the
heavy oil and allows the oil/water mixture (emulsion) to be
brought to the surface. The oil is recovered as product and the
produced water is de-oiled and treated for reuse in steam
generation. To treat de-oiled produced water, surface facilities
use traditionally a combination of warm or hot lime softening
(WLS), filtration, and weak acid cation (WAC) ion exchange.
The pre-treated water is recycled and sent to ``Once Through
Steam Generators`` (OTSG) which produce an 80% quality
steam. The steam-water mixture is sent through a series of
separators to produce the 100% quality steam required for
injection into the oil well. |
