Storage Project Application

Apply to implement, modify or expand a storage project related to hydrocarbon underground storage, salt cavern waste disposal, geothermal production and CO2 storage (non-EOR) in Saskatchewan.

1. Guidance

An operator must apply to and receive authorization from Saskatchewan's Ministry of Energy and Resources through the Integrated Resource Information System (IRIS), before licensing, recompleting or reclassifying a well associated with a specific storage project, as outlined in Section 17 of The Oil and Gas Conservation Act.

There are three application types in IRIS related to storage operations:

  • Storage Project – A storage project means a development for the storage of hydrocarbon in underground reservoirs and salt caverns, and the disposal of wastes in salt caverns.
  • Geothermal Project – A geothermal project means a development where geothermal energy is recovered through deep well(s). There are two main types of geothermal project; open-loop and closed-loop. An open-loop system includes: (1) withdrawing formation water for the purpose of extracting geothermal energy as part of an industrial process, and (2) disposing the cooling fluids into subsurface following the extraction of its heat content. In an closed-loop system, the source fluids are circulated in a sealed wellbore – heat exchange loop and there are no formation fluids to be withdrawn or fluids to be disposed. The geothermal project application is only applied to the subsurface activities.
  • CO2 Storage Project – A CO2 storage project means a development that is the long-term isolation of CO2 in subsurface geological formations, and is primarily applicable to saline aquifers and depleted hydrocarbon reservoirs. It does NOT preclude to storage associated with hydrocarbon recovery – CO2 Enhanced Oil Recovery (EOR), and does NOT include CO2 storage in unminable coal beds, basalt formations, shales, and salt caverns, and disposal of acid gas.

2. Eligibility

To apply for a storage project authorization, applicants must:

  • Have an IRIS account and the appropriate permissions assigned by your IRIS Security Administrator.
  • Complete the required public notices as outlined by the Directive PNG009: Public Notice Requirements.
    • It's the responsibility of the applicant to identify any potentially or directly affected parties outside of the minimum notification area and provide notification to these parties.
  • Meet the requirements outlined in Directive PNG008: Disposal and Injection Well Requirements Directive.
  • Specifically,
    • Storage Project: Meet the requirements according to the latest edition of the Canadian Standards Association (CSA)'s Standards:
      • CSA Z341.1 & 2: Storage of Hydrocarbons in Underground Formations
      • CSA Z341.4: Salt Cavern Waste Disposal
    • Geothermal Project: a project feasibility study is expected to be completed prior to the application submission.
    • CO2 Storage Project: if the proposed storage pool is a depleted hydrocarbon pool (including associated aquifer), and if incremental production is anticipated as a result of the proposed injection, consider applying for CO2-EOR rather than CO2 storage.

3. How To Apply

To apply for a specific storage project authorization:

  1. Ensure you meet all eligibility requirements.
  2. Complete the:
  3. Complete the Reclassification/Recompletion (part of a reservoir) Application Form with all the necessary attachments (as one document), if required. For more information, see Guideline PNG024: Reclassification and Recompletion.
  4. Compile the applicable supporting documentation:
    • Well list
    • Third-party Engineering Report (Confidential)
    • Seismic Data and Report (Confidential)
    • Public Notice Package/Consents
    • Other supporting documents (if applicable)
  5. Log in to IRIS and complete the appropriate application process for authorization and attach the required documents as separate files.

Once an application package is submitted through IRIS it cannot be modified by the applicant. Any subsequent changes or additions require resubmission.

5. Further Information

  • The applicant will be notified through IRIS whether the application for authorization is approved or denied.
  • The applicant has one year to use an authorization before it expires. An authorization number may be used multiple times if it’s issued approving multiple wells/operations. The authorization won't expire if it is used at least once within the one year period.
  • New wells approved as part of a storage project receive an authorization number that can be used to obtain a well licence through IRIS.
  • If injecting fluids in undisposed Crown Lands, a lease of space agreements must be executed with Crown on application in IRIS by providing the authorization number or well licence number. Refer to Non-Advertised Dispositions and Non-Advertised Dispositions Application for more information.
  • An approved project may require additional reporting. These requirements are detailed in the project authorization. Any submitted progress reports are held confidential indefinitely by the ministry.
