Apply for Enhanced Oil Recovery Projects

Apply to implement, modify, or expand an Enhanced Oil Recovery (EOR) project in Saskatchewan.

Top

1. Guidance

An EOR project improves the recovery of oil by injecting a substance other than water into a hydrocarbon bearing formation. The main techniques used for EOR include thermal, chemical, gas, and microbial injection. 
  

As outlined in Section 54 of The Oil and Gas Conservation Regulations, 2012, an operator must apply for and receive approval from the Minister of the Economy before beginning any work on wells for the purpose of an EOR project. This applies to both pilot and full-scale EOR projects, as well as modifications and expansions. 

For Thermal Enhanced Oil Recovery (EOR) projects the submission of a Measurement Accounting and Reporting Plan (MARP) is required. Please see Guideline PNG042: Measurement Accounting and Reporting Plan for details regarding information required in the plan.

  • For new thermal EOR projects the submission of a MARP is required at the time of the submission of the EOR Application.
  • For existing thermal EOR projects that are being modified, the submission of a MARP submission will be required if the licensee changes an existing thermal EOR project, including new or additional wells and or surface facilities, when the licensee does not incorporate the same production, operating, measurement, and accounting processes approved under the original MARP. The revised MARP will be submitted as an addition to the EOR Modification application.
  • For existing thermal EOR projects that are not being modified and for project that do not have an approved MARP, ECON will not require the submission of a MARP.

2. Eligibility

An application for an EOR project can be made when:
  • The project is expected to provide incremental recovery.
  • The operator seeks to prove that the technology can be used under field conditions (proof of concept).
  • The process won’t negatively affect the reservoir. 
  • There are sufficient safety measures in place to mitigate any potential risk to people and the environment.
  • The project is contained within the proposed area so it won’t pose a risk to adjacent mineral stakeholders and operators.
  • There is a dedicated monitoring program in place to track the progress of the project.
  • The Ministry of the Economy is made aware of any issues with the project, and provided with yearly progress reports unless otherwise stated. 
The applicant must have an Integrated Resource Information System (IRIS) account and the appropriate permissions assigned by their IRIS Security Administrator to submit an EOR project application.

3. How To Apply

To apply for a new, expansion, or modification of an EOR project:

  1. Complete the Enhanced Oil Recovery Application Form and include all required attachments; see Form Instructions tab of the application.
  2. Complete the Public Notice Process, if required.
  3. Obtain written consent for the project from all Freehold mineral owners within the drainage area of the proposed injection well(s), if required.
  4. Complete the Reclassification/Recompletion (part of a reservoir) Application Form with all the necessary attachments, if required. For more information, see Guideline PNG024: Reclassification and Recompletion.
  5. Confirm that all the information is complete and accurate, and forms are dated and signed. Ensure all required attachments are included:
    • Enhanced Oil Recovery Application form
    • Reclassification/Recompletion (part of a reservoir) Application Form with all the necessary attachments
    • Maps
    • Production charts
    • Required log cross-section, cement log and casing log analysis
    • Well list
    • Well surveys
    • Confidential attachments:
      • Information can be attached as confidential as long as there is enough detail in the application to support the EOR project application
      • Confidential information includes: 
        • Third-party engineering reports;
        • Seismic mapping; and
        • Detailed breakdown of the composition of the injected substance. i.e. cyclic-solvent-CO2 composition
      • Other relevant information can be attached in an appendix
      • Completed Public Notice Process package, documented objections and required consents as a separate document if applicable
  6. Log in to IRIS and complete the appropriate process for authorization and attach the required documents.
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

EOR authorizations are valid for one year from the approval date.

Progress Reports

An approved EOR project may require additional reporting. These requirements are detailed in the project authorization. Any submitted progress reports are held confidential indefinitely by the Ministry.

Minimum requirements to be included in an EOR project or EOR pilot annual report include:
  • A general description of project development and operations for the appropriate time frame, including:
    • Total number of injection wells;
    • Total number of producing wells;
    • Total injection wells converted for the year; and
    • Any other significant changes to that were made.
  • A detailed production report for the project
  • An injection record for the project
  • A brief operating and capital cost record
  • An evaluation of the success of the project to date, including the percentage of oil recovery at present and the predicted ultimate recovery. Include an estimate of the swept area, and the sweep and displacement efficiencies if possible
  • Future plans for the project and an estimated timeline
Reports are due on March 31 each year unless otherwise stated in the project approval.
