Submitting, changing, and rescinding applications
Use this process to do the following:
- Submit a new well spacing application.
- Rescind approved spacing.
- Modify spacing.
After you review spacing attributes in an area of interest, launch the ERCB's Digital Data Submission (DDS) system to complete an online spacing application using the ERCB Electronic Application System (EAS). Using the EAS form, select an application purpose of New Spacing, Rescind Spacing, or Modify Spacing. For criteria around submitting spacing applications, see AER Directive 065.
While completing the form, a View Map button on the EAS form enables you to launch the Well Spacing Map. Use the Spacing Application tab of the Well Spacing Map to click areas on the map to add to your EAS application. These details are automatically added to your EAS application.

The Spacing Application tab is only available when you launch the Well Spacing Map using the EAS form.
To submit spacing applications
- Launch the DDS website, log on, and then select ERCB > Applications > Facilities/Resources Application > Submit Resources Application.
- Complete Resources Applications - Schedule 1 selecting an Application Type of either Spacing: Gas or Spacing: Oil and an Application Purpose of Modify Spacing, New Spacing, or Rescind Spacing.
- Click Go To Form and start the Directive 065 Spacing Application form.
Help is available from EAS by clicking the Help button in each section of various forms.

- In Section 3 Area of Application of the EAS form, click View Map as depicted below.
The Well Spacing Map launches.
- Either using the Navigation tab or the toolbar buttons, navigate to an area of interest.
Your map must be at a scale of 1:150,000. For details on navigating the Well Spacing Map, see Narrowing the map focus.
Note: It's a good idea to enable the Schedule 13A and 13B layer using the Layers tab of the Well Spacing map. If your desired area falls within one of the development entity areas, the standard well density is automatically increased and you may not need to complete a well spacing application. See AER Directive 065 for details.
- Click the Spacing Application tab.
- Complete the numbered steps on the Spacing Application tab as follows:
- Step 1 - Use the Navigation tab to narrow the map window to a distance of two townships by two ranges. See Narrowing the map focus for details.
- Step 2 - Select the Start Spacing Application check box to disable the Well Spacing map toolbar while you specify details to automatically add to your EAS Spacing application. You can't navigate the map and populate the EAS form at the same time.
The map is redrawn at a scale of 1:150,000.
Tip: To enable buttons in the map toolbar, click Enable Map Toolbar at the bottom of the Spacing Application tab. - Step 3 - Click either Formation or Field/Pool.
The appropriate drop-down list appears below the radio buttons.
Using the drop-down list box, select the name of the desired formation, or field/pool, and then click
to include it in your list.
To remove an item from your list select it in your list, and then click
.
For Field/Pool, if completing a New Spacing or a Modify Spacing application, only active fields in the current map extents and active pools in both the current map extents and relevant for the selected field appear in the drop-down list. If submitting a Rescind Spacing application, all approved fields regardless of map extents can be selected. - Step 4 - Click the size of area that will be selected each time you click the Well Spacing Map. Different sizes of areas can be combined in the same EAS application.
For LSD selection, the map scale zooms to 1:75,000. - Step 5 - Click an area(s) on the map to include in your EAS form.
If you click the wrong location on the map, clear it from your selections by clicking Removal by click on map (
) and then clicking the undesired selection on the map.
To remove all selected locations either click Clear all map areas (
), or click the Remove button that appears above the attribute table below the map.
Click Display Area of Application (
) to centre the selected parcel(s) in the map window. If your selections include locations at opposite sides of the map, the map may not move at all, so that at least a portion of all of the selections remain visible.
Note: You can't select more than 36 sections for an application, and all of your selections must be within a distance of two townships by two ranges.
As you click, your selections are added to the attribute table below the map and to your EAS form.
Note: If the township/range label appears on a section line that divides an area in which you're interested, zoom in so that the township/range label isn't covering a spacing boundary. In the following image, the township/range label obscures a spacing boundary.
- Step 6 (holdings and units only) - If ownership isn't common or locations aren't adjacent, click to add an additional holding, and then click the desired locations on the map.
Note: To remove a holding using Removal by click on map (
), the holding to remove must be displayed in the Current Holding drop-down list that appears in Step 6.
The map displays an incremented number on the area you just selected and a second attribute table appears below the map.
- After you select all of the areas to include in the application, click Return to EAS Form and complete the outstanding portions of the form.
The area selections you made using the Well Spacing Map automatically appear in the EAS form.
Applications are visible on the well spacing map within 10 minutes of being submitted or approved.
