An integrated process for production and upgrading of heavy and extra-heavy crude oil, comprising (a) reforming of hydrocarbons such as natural gas to produce hydrogen, CO2 and steam (b) separating the produced hydrogen from th e CO2, steam and any other gases to give a hydrogen rich fraction and a CO2 ri ch fraction and steam, (c) injecting the steam alone or in combination with the CO2 rich fraction into a reservoir containing heavy or extra heavy oil to increase the oil recovery, and (d) upgrading/refining of the heavy or extra heavy oil to finished products by extensive hydroprocessing, comprising several steps of hydrocracking and hydrotreating (sulfur, nitrogen and metal s removal as well as hydrogenation of olefins and aromatics), using the hydrog en rich fraction. |
