CNGD

Canadian National Geothermal Database

In conjunction with the Geothermal Favourability Map of Alberta, this web portal has been established to host a publicly accessible Canadian National Geothermal Database (CNGD).

The CNGD initiative is in line with the goals of the global geothermal industry, namely that:

    - Improve accessibility of information and knowledge as a risk mitigating effort in geothermal
    - Reduce fragmentation of data collection and avoid duplication of efforts
    - Increase reliability of available data
    - Increase awareness of geothermal energy potential and utilization

The format of the web portal is designed to be user-friendly and flexible, allowing data to be retrieved as multiple different file types, including detailed spreadsheets and Google Earth maps and data. These files contain specific geological, geophysical, environmental and/or other criteria useful in assessing and identifying geothermal resource potential.

Similar to the U.S. National Geothermal Database (‘NGDS’: www.geothermaldata.org), the CNGD stores critical geothermal site attribute information including: temperature at depth, thermal conductivity, heat flow, well logs, bottom hole temperatures (BHT), drill stem test (DST), permafrost data, seismicity/microseismicity, porosity/permeability data, water chemistry, and geophysical surveys. It will also be inclusive of all types of geothermal resources such as direct-use, hydrothermal, hot sedimentary aquifer, geopressured, Enhanced Geothermal Systems (EGS), geothermal fluids co-produced with oil and/or gas, and others.

Data sources include historical data and existing geothermal resource assessment data already compiled by universities, research organizations, as well as private and publically funded geothermal exploration projects. The database will also be used to assess regions of Canada that lack the required data for assessing geothermal potential. The CNGD will provide a level of confidence consistent with geothermal reporting codes. It has been made available to the public and will serve as a geothermal exploration tool for making informed business decisions, as well as a means for mitigating investment risks. The database has been initially established and hosted by CanGEA until completion of this project or until a more suitable long-term host can be provided.

At this time, CanGEA would like to invite all interested parties to join the CNGD as a data contributor. More information on this project can be provided upon request.

Geothermal Favourability Maps of Alberta


Despite the abundance of widespread geothermal resources, a geothermal power industry has yet to develop in Canada due, in part, to a lack of understanding of the resource potential and the technologies available to harness the resources. In order to unlock Canada’s geothermal potential and encourage exploration and investment, key geothermal resources need to be well defined and inventoried.

In partnership with Suncor Energy, the Pembina Institute and Alberta Innovates Energy and Environment Solutions, CanGEA is currently facilitating the development of a Geothermal Favourability Map of Alberta that follows a Global Protocol. The purpose of the project is to provide publicly available maps, databases, protocols, and tools which may be used as a resource and/or investment tool for assessing and exploiting geothermal resources in Canada.

Apart from other resource maps developed in Canada, the map will follow international guidelines already adopted in the U.S. and Australia, and adapted for compliance with the ‘Canadian Geothermal Code for Public Reporting’ (www.cangea.ca/code). Presented to the public in a universal mapping platform and centralized national geothermal database, the project deliverables will also provide a means to share, collaborate or update data necessary for making informed business decisions.

The Canadian version of the Protocol for estimating geothermal resources will be made public following a detailed review from ‘Qualified’ individuals from the Australian Protocol development team, along with authors of the Canadian Geothermal Code for Public Reporting. Anticipating any future changes and/or advancements in geothermal technology, the Canadian version of the Protocol will also serve as a ‘living document’ and will remain open to continuous review.

Upon successful completion of this project, the Alberta Geothermal Favourability map will be made publically available. While Alberta is the first province to adopt these international guidelines for assessing geothermal resources, it is anticipated that other provinces and territories will follow (a British Columbia Favourability Map is scheduled to be completed in 2013). The favourability map and subsequent database will not only ne used to investigate areas in Canada with high geothermal anomalies but also identify regions of little or no data available to promote further data collection and research.
