Zusammenfassung:	A method for producing a heavy crude oil from a subterranean formation through a wellbore and converting the heavy crude oil into a product distillate hydrocarbon stream and at least one of heat, steam, electricity and synthesis gas by separating distillable components of the heavy crude oil by distillation and converting the residual portion of the heavy crude oil in a fluidized bed to at least one of heat, steam, electricity or synthesis gas. The method also produces diluent hydrocarbons useful in the production and transportation of the heavy crude oil. In one embodiment the heavy crude oil is mixed with a diluent to form a mixture which is then transported to a selected location for conversion of the heavy crude oil. The diluent is typically a hydrocarbonaceous distillate material which may be recovered as a separate product as part of the conversion step. L'invention concerne un procédé de production d'un pétrole brut lourd à partir d'une formation souterraine, au moyen d'un puits de forage, et de conversion de ce pétrole brut lourd en un courant d'hydrocarbures contenant des distillats et en au moins une des fractions suivantes: chaleur, vapeur, électricité ou gaz de synthèse. Ce procédé consiste à séparer des constituants distillables du pétrole brut lourd par distillation et à convertir la portion résiduelle du pétrole brut lourd, dans un lit fluidisé, afin d'obtenir au moins une des fractions suivantes: chaleur, vapeur, électricité ou gaz de synthèse. Ce procédé permet également de produire des hydrocarbures diluants, utiles dans la production et le transport du pétrole brut lourd. Dans un mode de réalisation, on mélange le pétrole brut lourd avec un diluant afin de former un mélange que l'on transporte ensuite sur un site choisi de conversion de ce pétrole brut. Le diluant est généralement un produit de distillat hydrocarboné que l'on peut récupérer en tant que produit séparé faisant partie de l'étape de conversion.
