With the Geothermal Resource Estimate Maps of the provinces of Alberta and British Columbia in Canada, and in support of Open Data, the Canadian Geothermal Energy Association (CanGEA) has established a web portal to host a publicly accessible Canadian National Geothermal Database (CNGD).

In conjunction with the Geothermal Resource Estimate Maps of the provinces of Alberta and British Columbia in Canada, and in support of Open Data, CanGEA has established a web portal to host a publicly accessible Canadian National Geothermal Database (CNGD). This open-source platform responds to one of the industry’s barriers to geothermal energy development and deployment: the difficulty in accessing and integrating technical data in a digital format.

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.

There are currently databases/maps for 3 provinces/territories: Alberta, British Columbia, and Yukon.

CNGD Features

  • 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
  • Geophysical surveys
  • Geothermal resources  (direct-use, hydrothermal, petrathermal, hot sedimentary aquifer, geopressured, geothermal fluids co-produced with oil and/or gas)

The database was established and is hosted by CanGEA. Data sources include historical data and existing geothermal resource assessment data already compiled by universities, research organizations, as well as private and publicly funded geothermal exploration projects. Data sources include historical data and existing geothermal resource assessment data already compiled by universities, research organizations, as well as private and publicly funded geothermal exploration projects.

The Canadian version of the Protocol’s methods and data sources for estimating geothermal resources is public and available 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.

Canadian Geothermal Code for Public Reporting

Distinct from other geothermal resource maps developed in Canada, the maps follow international guidelines already adopted in the U.S., Australia, South Korea, Spain, and Europe and have been adapted for compliance with the ‘Canadian Geothermal Code for Public Reporting.’ Presented to the public in a universal mapping platform and centralized national geothermal database, the project deliverables also provide a means to share, collaborate or update data necessary for making informed business decisions.

The Database access can be reached via the CanGEA Website.
