What is the library?
A working library for petroleum, salt, storage, and subsurface projects in Ontario.
The OGSR Library is a business and research resource centre focused on Ontario's subsurface geology and petroleum activity. It combines physical materials, digital records, maps, publications, and staff support so users can move from a single well record to broader geological interpretation and operational decisions.
The collection supports work involving drilling, production, geological review, storage, solution mining, compliance, municipal planning, land evaluation, and historical research. Some resources are public, some are member-only, and some are provided through staff-assisted service.
The OGSR Library is operated by the Ontario Oil, Gas & Salt Resources Corporation, a not-for-profit corporation. In Ontario the industry is regulated by the Petroleum Operations Section of the Ministry of Natural Resources.
1. Start with a well, map, or question
Most users begin with a licence number, a township location, an operator name, or a map area. Use Wellcards, the map viewer, or request staff help if you need to narrow the search.
2. Move into reports and technical context
Once the well or area is identified, connect it to drilling reports, production data, geological references, map products, and publications.
3. Visit, order, or request assistance
Use the physical library, request copies, order products, arrange research support, or contact staff for project-specific help.
Well data and lookup tools
Use the fastest search and reference tools for active project work.
Maps and spatial context
Move from a location to surrounding wells, pools, spacing, and supporting regional data.
Reports and publications
Use current and historical publication sets to support interpretation, reporting, and long-range review.
Library services and catalogues
Plan a visit, check service costs, and access additional reference collections.
Submitting core and cuttings
For operators who have rock cores or cuttings from a newly drilled well:
Operators must comply with the regulator's sampling specification under the Provincial Operating Standard version 3.
To comply with this standard operators must properly collect, label, and then submit samples to the OGSR Library and submit the sample fee.
Exploration teams
Use well history, stratigraphic context, maps, and reports to screen targets and compare nearby activity.
Producers and operators
Access production records, drilling history, forms, and sample submission information needed for ongoing operations.
Municipalities and planners
Review spatial activity, land context, and legacy petroleum records that may affect planning and infrastructure work.
Governments
Petroleum well data and physical rock samples provide the necessary raw data to support important decisions and planning.
Landowners and rights holders
Locate wells, review activity in an area, and understand the historical record before contacting the library for help.
Consultants, researchers, and educators
Use publications, maps, sample materials, and archived technical references to support studies and teaching.
Maps, data products, and printing
Order map products, request plotted outputs, or use the library to locate the right dataset before purchasing a larger package.
3D printed geology models
Use physical models for communication, education, meetings, and subsurface interpretation support.
Online store
Some standard products are available directly through the store while custom requests still route through the library.
Use the OGSR Library the way your project demands.
If you already know the well or area, start with Wellcards or Maps. If you need broader context, move into downloads, reports, and publications. If you need staff help, visit the library or send a request.
