Liard Basin Shale Study

YGS is currently involved in three multi-jurisdictional collaborative projects in Liard basin, all of which relate to furthering our understanding of unconventional oil/gas reservoir potential and resource volumes of the basin’s Upper Palaeozoic shale sequences.

Devonian – Missisippian Shale Studies
YGS is working in collaboration with the Geological Survey of Canada, the Northwest Territories Geoscience Office (NTGO) and the British Columbia Ministry of Natural Gas Development (BCMNGD) on efforts to improve the understanding of prospective Devonian-Mississippian shale gas strata in Liard basin. The study was initiated in 2012 with a reconnaissance survey of shale outcrop exposures and detailed measuring of Besa River sections in Yukon and B.C., and a Mississippian Golata Formation section in N.W.T. Goals are to refine the Upper Devonian – Mississippian stratigraphy of the region where unit nomenclature is inconsistent, and to evaluate the shale sedimentology, distribution, and hydrocarbon potential. A joint publication on 2012 field data is forthcoming.

A report on the Besa River Formation exposure measured in Yukon was published as:

Hydrocarbon liquids fertility & play prospectivity in Liard Basin
YGS is working in collaboration with the Geological Survey of Canada (GSC), NTGO and the BCMNGD on a project designed to address knowledge gaps in:
• our understanding of the relationship between a basin’s multistage thermal history and its reservoir quality and unconventional hydrocarbon play productivity, and;
• the distribution and character of a potential new resource play in the Liard Basin for unconventional hydrocarbon liquids.
This study is being directed and funded by the GSC’s ‘Program of Energy Research & Development’ project (PERD). YGS is providing jurisdictional geoscience expertise as the study encompasses the entire Liard Basin, and will focus its efforts on targeted sampling (and/or resampling) of the Upper Devonian to Mississippian Besa River Formation in key wells.

Unconventional resource assessment

The Liard Basin unconventional resource assessment was released by the National Energy Board on March 16, 2016.
