The Alberta Energy Regulator (AER) ensures the safe, efficient, orderly, and environmentally responsible development of hydrocarbon, geothermal, and mineral resources over their entire life cycle. As part of this mandate, we provide our stakeholders with credible information about Alberta’s energy resources that can be used for decision making.

We issue a report each year that provides independent and comprehensive information on the state of reserves and the supply and demand outlook for Alberta’s diverse energy resources: crude bitumen, crude oil, natural gas, natural gas liquids, coal, and emerging resources. The 2023 report includes a new section on emerging resources for lithium.

The ST98 report provides estimates of initial established reserves (recoverable quantities estimated to be in the ground before any production), remaining established reserves (recoverable quantities known to be left in the ground), and ultimate potential (recoverable quantities that have already been discovered plus those that have yet to be discovered). It also includes, for Alberta’s energy resources, supply and demand data for 2022 and a ten-year supply and demand forecast for 2023-2032 (the forecast period). Additionally, this report discusses prices and capital expenditures in the oil and gas sector and pipelines and other infrastructure related to Alberta’s energy resources.

Electronic data files for crude oil and natural gas reserves and PDF maps of designated fields, oil sands areas, development entities, and documents related to ST98 are available for free from the AER's product and services catalogue. A historical reserve file is available for purchase on the same product catalogue.

The ST98: Alberta Energy Outlook 2023 executive summary [PDF] and the report highlights infographic [PDF] are available for download in PDF format.
