AbstractRock-Eval analysis of samples from the organic-rich Radioactive Zone of the lower Garbutt Formation indicate that this horizon is: dominated by Type II kerogen; is currently within the oil generation or wet gas zones; and has average total organic carbon contents over 3 per cent. Subsurface mapping shows that the top of the Radioactive Zone occurs at a depth of between 1500 and 2000 m west of the Bovie structure and that the southern part of this area reaches thermal maturities within the wet gas zone (Tmax 450 to 460o C).
Summary(Plain Language Summary, not published)
Subsurface mapping combined with organic geochemical characterization through rock-Eval analyses has shown shales forming the Radioactive Zone in the late Lower Cretaceous Garbutt Formation are dominated by organic matter appropriate for generating liquid petroleum. In the BC Liard basin these are currently within the oil generation or wet gas zones, have total organic contents over 3 per cent and have depths between 1500 and 2000 m. The wet gas zone occurs in the southwest part of the basin and may form a potential liquids-rich unconventional petroleum play.
