AbstractThe Liard Basin is a highly prospective shale gas basin located in northeast British Columbia that is largely underrepresented in public literature. We used available-for-purchase 2D seismic data in the area to create a high-level, regional stratigraphic interpretation of the basin, providing the first seismically controlled overview of the basin structure and stratigraphy. The basin is characterized by two distinct, opposing wedges of sediment in the Mesozoic and Paleozoic sections: the Mesozoic with northeastward thinning and the Paleozoic with southwestward thinning. The wedging of the Upper Devonian-Lower Mississippian (Tournasian) section is dominated by multiple large packages of clinoforms, which progress into the basin from northeast to southwest and are predominantly seen in the seismic sequence stratigraphy. These distinct packages of clinoforms indicate changing sediment sources over time. In contrast, there are no clinoforms seen in the Mesozoic section, which may be a limitation of the orientation of the 2D seismic data that we used. Our result from the seismic interpretation is an updated interpretation of the Upper Devonian-Lower Mississippian stratigraphy of the Liard Basin, including an updated stratigraphic cross section for the area.
