The study area contains oil reservoirs in Cretaceous and Upper most Jurassic Formations, at different depths and in a variety of lithologies. There is having in the same area, several possible source rocks for such hydrocarbon.

The term "solid bitumen", as used in this study, implies in a general sense an immovable and highly viscous, or solid, oil-derived precipitate under reservoir conditions. Several natural processes leading to the deposition of solid bitumen in a reservoir have been proposed in the literature since they were first reported in the Western Canada basin in the early 1970, Three principal processes which are the most frequently cited in the literature are thermal alteration, deasphalting, and biodegradation. Thermal alteration (maturation) of pre-existing liquid hydrocarbons to form hydrogen-depleted carbonaceous residues and associated gases can result in deposition of solid bitumen in the carrier bed and reservoir at an elevated temperature.
