ABSTRACT:
An integrated process for extracting and refining bitumen comprises hydroconverting bitumen in a reactor to provide valuable products and light oil by-product; separating the light oil by-product from the valuable products; transporting the light oil to oil sands reserves; producing steam in steam generators at the oil sands reserves using a portion of the light oil transported to the oil sands reserves; extracting bitumen from the oil sands reserves using steam produced in the steam generators; blending bitumen extracted from the oil sands reserves and a portion of the light oil transported to the oil sands reserves to form a transport blend; and transporting the transport blend to the reactor.
