Abstract:
A method for producing a heavy crude oil from a subterranean formation penetrated by a wellbore, transporting the heavy crude oil to a market location and converting the heavy crude oil into a product distillate hydrocarbon stream and by-products comprising at least one of heat, steam, electricity and a synthesis gas, the method comprising:a) producing the heavy crude oil from the subterranean formation via the wellbore;b) diluting the heavy crude oil with a suitable diluent and transporting the heavy crude oil to a market location;c) distilling the heavy crude oil at the market location in a crude oil distillation zone to produce a distillate hydrocarbon stream having a boiling range at atmospheric pressure below about 770.degree. F. and a heavier hydrocarbon stream having a boiling range at atmospheric pressure above about 710.degree. F.;d) separating a deasphalted oil stream from the heavier hydrocarbon stream in a deasphalting zone to produce a deasphalted oil stream and a residual asphaltic stream; and,e) passing the residual asphaltic stream and a sulfur-reactive compound to a fluidized bed combustion zone for at least partial combustion to produce at least one of heat, steam, electricity and a synthesis gas.
