A sub-surface hydrocarbon production system comprising an energy delivery well extending from the surface to a location proximate a bottom of the hydrocarbons to be produced. A production well extends from the surface to a location proximate the hydrocarbon and a convection passage extends between the energy delivery well and the production well thereby forming a convection loop. The energy delivery well and the production well intersect at a location proximate the hydrocarbon such that the convection loop is in the form of a triangle. Preferably, the convection passage extends upwardly from a point at which the convection passage intersects the production well. The system also includes a heater, such as an electric heater or down-hole burner, disposed in the energy delivery well.
