Search by well record information
Well record searches require at least 1 of the following fields to be filled out.
| Type of search | Example | Notes |
|---|---|---|
| Well ID | 1100048 1100048,1100399,1100026 | A 7-digit number. Multiple well IDs are separated with commas. |
| Tag number | A051819 A051819, A074904 | A 6-digit number starting with A. Multiple tag numbers are separated with commas. |
| Audit number | Z59419 Z59419, 265899 | Multiple audit numbers are separated with commas. |
| Contractor licence number | 7454 | Contractor licence is a number with 4 digits. |
| Date of completion | 2010 03 27 or 2010 03 or 2010 | You can search by a date range. Enter both “From” and “Until” to find wells completed between those dates. Enter only “From” to find wells completed after that date, or only “Until” to find wells completed before that date. Year is required, month and day are optional. |
| Well depth (metres) | 100.1 to 101 | Well depth searches use a range. If you enter both values, the search returns wells with depths between those values. If you enter only the first value, it returns wells deeper than that depth. If you enter only the last value, it returns wells shallower than that depth. |
Search by custom area
Click “Draw custom area” on map. Click on the map to draw your area. Each click adds a point and lets you change direction.
When you are finished, double‑click or press “Enter” to complete the area, then click “Search” to view results.
Searches return a maximum of 2,000 wells. If you draw a large area, only the first 2,000 wells will appear.
Search by township, lot and concession
Search for a geographic township, then enter the lot and concession. Lot and concession fields require prefixes such as “LOT” or “CON.”
