AbstractCrude oil samples from the Cretaceous Chinkeh Formation of Maxhamish filed and black shale samples from the Cretaceous Garbutt Formation from the Liard Basin have been subjected to detailed organic geochemical analyses. Their biomarker signatures indicate that the Cretaceous Garbutt Formation shale have contributed to the hydrocarbon accumulations in the underling conventional sandstone reservoirs in the Chinkeh Formation at Maxhamish field. While providing geochemical evidence for significant oil generation in the Garbutt shales in the Liard Basin, this further implies that the Garbutt shale can be a significant liquids-rich unconventional shale hydrocarbon play where the shale interval is thick and oil expulsion has not been efficient.
Summary(Plain Language Summary, not published)
Results from geochemical analyses indicate that oil generated in the Cretaceous Garbutt black shale have migrated and accumulated in the underlying Chinkeh Formation sandstone reservoir at Maxhamish field. While providing geochemical evidence for significant oil generation in the Garbutt shales in the Liard Basin, this also implies that the Garbutt shale can be a significant unconventional light oil drilling target where the shale interval is thick and oil expulsion has not been efficient.
