About the collection
Numbers and original filings together
The production database supports comparisons by reporting year, operator, well, and pool. Scanned forms remain available alongside the tabular records so members can verify source material and browse filings that have not been fully digitized.
1967 to 1992
Generally annual values. These records may not be in the monthly volumes database, but can still be found by licence, operator, year, or binder.
1897 to 1967
Earlier records are commonly pool, township, or summary filings. Use scanned binders and source images when well-level monthly fields are not available.
Reporting context
Ontario production reporting
Reports on well production, status, injection, fluid disposal, and geophysical or geochemical exploration are submitted annually for activity in the previous calendar year. Most digitized monthly production is derived from Form 8 records.
Annual Well Status Report (Form 3)
Operators with unplugged wells report the annual status of each well. Form 3 also summarizes wells owned by an operator, production volumes by operator, and licence fee calculations.
Annual Geophysical/Geochemical Surveys (Form 4)
Geophysical or geochemical exploration for oil or gas must be reported annually to the Ministry for the preceding calendar year.
Monthly Injection (Form 6)
Injection wells report the volume of fluid injected into a formation on a monthly and cumulative basis. Annual PDF summaries are available from the injection reports page.
Monthly Oil and Gas Production (Form 8)
Producing petroleum wells report monthly fluid volumes, pressure readings, and days on production. Low-volume wells may be reported together on a commingled form.
Subsurface Oil Field Fluid Disposal (Form 9)
Disposal wells report the volume of fluid disposed into a formation on a monthly and cumulative basis. Annual PDF summaries are available from the disposal reports page.
Commingled wells
Under certain conditions, production from multiple wells may be grouped on a single Form 8. All wells in a commingled group must still be identified, and each well status must be reported separately on Form 3.
Tables and scanned annual PDFs
The member data area includes compiled production tables and scanned annual production PDFs. These downloads are useful for bulk project setup while the searchable production archive continues to expand.
Production tables
- Monthly production by well
- Production operator index
- Oil and natural gas production by pool
- Annual production by pool
- Wellhead shut-in pressure
Scanned annual records
Large PDF downloads are available for annual production binders from 2017 to current. The newest annual PDF is usually posted about eight months after year-end.
