NON CONDENSING GAS MANAGEMENT IN SAGD

The invention provides processes for producing mobilized bitumen and non-condensing gases from a radially expanding steam chamber in a SAGD process. Production of non-condensing gases is facilitated by systems for providing an axial pressure gradient along the longitudinal axis of the steam chamber,...

More Information
Summary:The invention provides processes for producing mobilized bitumen and non-condensing gases from a radially expanding steam chamber in a SAGD process. Production of non-condensing gases is facilitated by systems for providing an axial pressure gradient along the longitudinal axis of the steam chamber, so that the non-condensing gas flows in the axial dimension of the steam chamber in a convective flow motivated by the axial pressure gradient.
