A method for producing hydrocarbons from a region having adjacent strata divided by an impermeable or partially permeable barrier and, wherein at least one of the strata contains hydrocarbons, comprises of sufficiently heating one of the stratum to allow heat to be conducted to the hydrocarbon containing stratum and producing hydrocarbons therefrom. In one aspect, both strata contain hydrocarbons, such as bitumen, and heat is generated by a steam assisted gravity drainage process to the adjacent stratum. Heat may also be generated by in-situ combustion of hydrocarbons to preheat an adjacent stratum, or by electrical heating. Once pre-conditioned to a higher in-situ temperature, hydrocarbon production may be facilitated by diluting the target pre-heated hydrocarbon bearing stratum with solvent injection.
