Abstract
Non-condensible gases tend to accumulate at a steam
(condensation) front, and act as an insulating blanket on the
SAGD convection mechanism. This can have a material impact
on the drainage rate, for example as calculated by Butler's
equation for SAGD rate.
The effect of varying amounts of liberated solution methane
on a SAGD front is approached by calculating the temperature
drop that would be due to a given blanket thickness, and thus
deriving a correction factor to the normal (Butler) rate. In
addition to the usual petrophysical parameters, the corrected
rate is also a function of the reservoir GOR and the SAGD
operating pressures.
Results indicate that small amounts of accumulated
methane can reduce drainage rates by factors of up to 2 or
more. The required amounts are small fractions of the normal,
initial solution gas/oil ratio in the McMurray formation; it is
therefore concluded that further understanding of SAGD
chamber methane content, accumulation, and removal is
essential to confident reservoir forecasting and optimization.
