Abstract

Methods and systems produce petroleum products by steam assisted gravity drainage with dual producers separated vertically and laterally from at least one injector. Placement of the producers limits temperature rise of draining fluids and hence reflux of non-condensable gases injected with steam. In particular, the fluids drain along a steam chamber boundary for recovery at positions that are not in a direct downward path from where the injector is introducing heat.
